Introduction

Teledyne LeCroy's WaveLink 13-25 GHz Differential Probes utilize the latest design techniques and

components to achieve very high bandwidth, exceptional system (probe with oscilloscope) rise

times, low electrical noise, and high impedance over a wide frequency range. This is possible

through the use of a high bandwidth traveling wave (distributed) amplifier with high gain and low

noise, interconnect lead and tip designs that provide high impedance over a broad range of

frequencies, which reduces loading on the device under test, and lead/tip construction that enables

a nearly ideal terminating resistor to be located as close to the circuit as possible for superior

performance.

The WaveLink Series of High Bandwidth Differential Probes also utilize digital filtering to optimize

the system frequency response. The design of the WaveLink probe amplifier is such that there is a

very wide bandwidth response that exceeds the oscilloscope bandwidth. At time of initial shipment,

each probe undergoes a rigorous calibration and performance verification process that results in a

stored response file on-board the probe. When the probe is connected to a Teledyne LeCroy

oscilloscope, the probe and oscilloscope responses are optimized to each other to provide a probe +

oscilloscope response identical to that of the raw oscilloscope channel. Teledyne LeCroy has

provided this capability since the introduction of the first WaveLink probes in 2003. All that is left for

the operator is to de-embed the probe loading from the circuit using Teledyne LeCroy's Virtual

Probe software option, if desired. Since the Teledyne LeCroy probe impedance is very high across

the passband, this may not even be necessary.

Teledyne LeCroy’s WaveLink 13-25 GHz Differential Amplifier Small Tip Modules utilize either a

Dxx05 or Dxx05-A amplifier. The two amplifier series differ only in the Input Dynamic Range

specification – Dxx05 permit a 1.6Vp-p absolute signal swing and Dxx05-A permit a 2.0Vp-p signal

swing with specifications guaranteed and 2.4Vp-p max operating window. Otherwise, the operation

of the unit is identical, and this Operator’s Manual is used for either series. The same tips and leads

are compatible with both amplifier series.

To learn more about this probe series, Contact Teledyne LeCroy for Support.

NOTE:

 A Certificate of Calibration is supplied with each probe indicating the system meets

the specifications with those components listed in the Certificate.

 Download the latest version of X-Stream software to run your WaveLink probe with

maximum performance.

Modular Advantage

These probes use a pioneering modular design first introduced by Teledyne LeCroy's initial WaveLink

product releases. The modular design consists of a Platform/Cable Assembly, Differential Amplifier

Small Tip Module with Solder-in Leads, or Positioner Tip (Browser).

You may order nearly any combination of Platform/Cable Assembly and Amplifier Module (supplied

with Interconnect Leads) depending on the oscilloscope you have and your requirements. At time of

shipment, Teledyne LeCroy serializes the individual components and calibrates them as a system. To

achieve maximum performance and warranted specifications, the components should be used

together, as serialized. If additional Interconnect Leads or other components are purchased, you

may return the serialized system to Teledyne LeCroy for re-calibration to ensure performance.

NOTE: While the amplifiers can be used with either platform/cable assembly, system bandwidth is

components to guarantee system performance. Typically, a customer purchases a single

Platform/Cable Assembly that matches the Amplifier Module bandwidth rating.

Modular Probe Components

Platform/Cable Assembly

This piece forms the foundation of the probe and provides an attachment for the probe amplifier to

the oscilloscope. There are two different platform/cable assemblies available depending on whether

you are connecting to ProLink inputs currently used on ≥4 GHz Teledyne LeCroy WaveMaster 8 Zi/Zi-

A models, or to 2.92mm inputs used for 25-36 GHz signals on Teledyne LeCroy WaveMaster 8 Zi-A,

LabMaster 9 Zi-A, and LabMaster 10 Zi models.

Platform/cable assembly provided with WL-PLINK-A-CASE

Operator's Manual

WL-HBW-A-OM-E Rev B

Platform/cable assembly provided with WL-2.92MM-CASE

The Platform/Cable Assembly performs the following important functions:

 It provides power to the probe amplifier from the oscilloscope.

 It communicates to the oscilloscope the identifying characteristics of the amplifier that is

connected to the probe so that the oscilloscope channel can be set to the correct probe

attenuation value automatically. Software prompts you to specify the type of tip connected

to the amplifier when this occurs.

 It transmits the amplifier output signal along a well-defined low loss transmission line into the

oscilloscope input, and terminates the probe appropriately at that point.

NOTE: Legacy WL-PLINK platform/cable assemblies are not compatible with the D1x05-A or D2x05-A

13+ GHz amplifier modules. Only the WL-PLINK-A or WL-2.92MM are compatible.

LPA-2.92 mm to ProLink Probe Adapter

This adapter provides a simple and effective method to convert a Teledyne LeCroy ProLink interface

to a Teledyne LeCroy 2.92mm interface.

Teledyne LeCroy's 2.92mm interface utilizes a 2.92mm connector for the signal, and a

LEMO connection for probe power and communication. This interface is used for >20 GHz and <=36

GHz inputs on Teledyne LeCroy oscilloscopes.

Teledyne LeCroy's ProLink interface utilizes a blind-mate adapter (BMA) connector for the signal and

6-pin connection for probe power and communication.

In order to better leverage the complete probe system amongst all possible input types, the LPA-

2.92 may be used to adapt a WL-2.92MM platform/cable assembly to a ProLink connection - saving

you from having to purchase of an additional type of Platform/Cable Assembly. This adapter is

included standard with the WL-2.92MM-CASE.

Differential Amplifier Small Tip Modules

This module contains the active amplifier circuitry and performs the important task of amplifying the

low-level signal at the probe tip for transmission to the oscilloscope via the Platform/Cable

Assembly.

For this 13-25 GHz probe series, Teledyne LeCroy utilizes advanced differential distributed (traveling

wave) amplifier architecture to achieve superior high frequency broadband performance. A

distributed amplifier uses a transmission line to provide inputs to a series of amplification stages.

Another parallel transmission line is used to sum the outputs of each amplification stage. The two

transmission lines are designed with specific delay and impedance characteristics to ensure that the

amplification stages are summed correctly. Since the amplifier gain stages add rather than multiply

(as in a typical cascade design), it is possible to achieve high gain over a wide frequency range with

very low inherent noise. This provides the added benefit of a lower probe attenuation, which

enables the oscilloscope to be operating in an input range which itself requires lower gain, and

hence will typically have lower noise. In addition, higher bandwidths can typically be achieved with

this amplifier architecture. Since a pure distributed amplifier provides insufficient low frequency

response, an additional amplifier is integrated into the assembly for this purpose.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

This amplifier architecture provides the following:

 Very low probe only noise (≤18 nV/√Hz). Much less than other, comparable bandwidth

probes.

 Excellent system (probe and oscilloscope) rise times. In fact, the probe, when connected to

WaveMaster 8 Zi-A, LabMaster 9 Zi-A, or LabMaster 10 Zi oscilloscopes of the same

bandwidth, causes no reduction in bandwidth or rise time compared to the oscilloscope with

a cable input.

Differential Amplifier Small Tip Module

The amplifier module is sold with a set of solder-in interconnect leads. See Solder-in Interconnect

Lead (on page 10).

Solder-in Interconnect Leads

The probe lead provides ability to access the signal on the device under test (DUT) without

disturbing the operation of the DUT. The solder-in probe lead provides the highest possible

performance at the expense of a non-movable installation. The design of the solder-in lead

minimizes customer circuit loading with the probe connected by providing high probe AC loading

and a wide frequency range where AC circuit loading is minimized.

The solder-in lead supplied with the kit consists of two small, pre-installed and pre-trimmed

attenuating (damping) resistors connected to a flexible transmission line terminating in a connector

mating with the amplifier. Because resistors and resistor lengths are small, this solder-in lead

provides the maximum signal fidelity and minimum circuit loading at the highest frequencies. The

resistors are soldered directly into the connection points of the circuit under test, providing a

reliable, intermittence-free connection.

Five replacement damping resistors are provided with each solder-in lead. Resistors may be

replaced in the field if the tip is damaged. See Replacing Damping Resistors on the Solder-in

Interconnect Lead (on page 39) for more information.

NOTE:

 At initial product launch, there were two different solder-in leads - a D1x05-SI and a

D2005-SI. The D2005-SI was used with the 20 GHz and the D1x05-SI was used with

13 and 16 GHz amplifiers.

 Now, these solder-in leads have been replaced with a universal Dxx05-SI used for all

bandwidths (13-25 GHz). This lead can also be used as a replacement for the D1x05-

SI and D2005-SI.

Teledyne LeCroy's solder-in probe lead uses resistors at the tip that are precisely pre-cut to the

correct length. This design provides the following advantages:

 It locates the damping resistance of the probe tip as close to the DUT as possible.

 It eliminates the need for long lengths of wire between the DUT and the damping resistor,

which impacts loading and frequency response. The resistors may still be spaced as desired to

connect to a wide variety of circuits.

 It eliminates the need to precision cut and solder small lengths of wire to the end of the

solder-in lead, and then solder these wires to the DUT.

 The damping resistors are easily replaced in the field to provide maximum serviceability and

life of the solder-in probe lead.

WL-HBW-A-OM-E Rev B

Positioner Tip (Browser)

The Positioner Tip (Browser) provides the ability to access the signal on the DUT without

permanently attaching a lead or other device to the DUT. The positioner tip combines high

performance with quick access to a variety of probe points when it's used as a hand-held browser

(using the Wand attachment) or as a fast and convenient method to re-position a fixed test point

(using a positioner tool, like Teledyne LeCroy's Freehand Positioner, XYZ Positioner or EZ Probe .

The carbon composite resistive pogo pin tips are adjustable from 0 to 3.5 mm (0 to 0.14") and have

0.55 mm (0.022") of Z-Axis compliance. Because of its thin form factor and spring-loaded tips, it is

ideally suited for use with multiple probes in tight areas such as the back side of boards with ball-

grid array packaged ICs.

The Positioner Tip supplied with the kit consists of two small, pre-installed carbon-composite

resistive pogo-pin tips with crowned metal caps for solid connection to the circuit. The carbon

composite resistive tips place the tip resistance as close to the circuit as possible. In addition, the

nature of the material and design minimizes skin effect at higher frequencies, a common problem

with a single conductive tip. The Positioner Tip provides the maximum signal fidelity and minimum

circuit loading at the highest frequencies.

Care should be taken when using the Positioner Tip. While the carbon composite material in the tip

is very strong, the high bandwidth nature of the probe means the diameter must be very small.

Avoid lateral motion against the circuit trace with the tip, and do not exceed the pogo pin Z-Axis

compliance.

NOTE: Some mechanical positioners (such as the EZ Probe) might have the capability to exert

excessive Z-Axis compliance during setup, so be extra careful with these types of mechanical

positioners.

Two replacement resistive tips are provided with the Positioner Tip. These tips may be replaced in

the field if the tip is damaged. See Correctly Replacing Carbon Composite Resistive Pogo-Pin Tips in

Dxx05-PT (on page 42) for more information.

Probe Operation

Overview

Teledyne LeCroy WaveLink probes are factory calibrated and performance verified on shipment.

During factory calibration and performance verification, each probe amplifier has a response file

created and stored on-board. When the probe is connected to your Teledyne LeCroy oscilloscope,

the response file is read by your oscilloscope and a combined optimized probe + oscilloscope

response is created for your particular oscilloscope and channel to which the probe is connected.

The response is identical to that of the oscilloscope channel.

All that is left for the operator is to de-embed the probe loading from the circuit using Teledyne

LeCroy’s Virtual Probe software option, if desired. Since the Teledyne LeCroy probe impedance is

very high across the passband, this may not even be necessary.

NOTE: With your probe set up and system turned on, allow for a 15-minute warm-up of your probe

prior to use. A properly warmed-up probe ensures optimal measurements.

System Calibration

By design, the D1305-A, D1605-A, D2005-A, and D2505-A amplifier modules and interconnect leads

deliver the specified performance when interchanged on a WL-PLINK-A or WL-2.92MM

platform/cable assembly, or when an LPA-2.92-PLINK probe adapter is used.

Each configured probe is shipped with a Certificate of Calibration indicating that the system

performance was validated and found to meet or exceed the warranted specifications with those

models and accessories listed in the Certificate.

As only this configuration was validated, the certificate is only valid for the configuration indicated.

This is why all modular probe components are serialized, calibrated, and tested as a system before

being shipped from the Teledyne LeCroy factory, to ensure guaranteed performance.

A serial number is affixed to each module and the operator must ensure serial numbers on all

modules match.

NOTE: If you do not verify that serial numbers on the modules match, performance is not

guaranteed. If an incorrect, uncalibrated combination of amplifier modules and platform/cable

assemblies is connected together, a warning will be displayed on the oscilloscope screen.

The interconnect tips are designed to keep response within a narrow range so they are

interchangeable, and interconnect leads manufactured at the same time have nearly identical

performance. Likewise, if a damping resistor on the solder-in lead is replaced using the procedure

Operator's Manual

WL-HBW-A-OM-E Rev B

for Replacing Damping Resistors on the Solder-in Interconnect Lead (on page 39), performance is

still guaranteed. If an interconnect lead tip is damaged beyond field repair and requires factory

replacement, Teledyne LeCroy recommends you return the probe platform/cable assembly and

amplifier module to the factory for a complete calibration and test to ensure guaranteed

performance. This is because there may be small differences in performance of interconnect leads

supplied at different times.

If a positioner tip (PT) is purchased at time of original shipment of the other probe components, this

is also calibrated and serialized with the other components. If it is purchased at a later date and you

have provided Teledyne LeCroy with the original probe serial number the tip is used with, Teledyne

LeCroy calibrates the positioner tip to your existing components and supplies a file on a

USB memory stick for installation on your oscilloscope. Follow the instructions provided with the file

and memory stick in order to load this file and ensure proper calibrated performance with your

existing probe components.

Finally, if the carbon composite resistive pogo-pins need to be changed on your PT tip, see Correctly

Replacing Carbon Composite Resistive Pogo-Pin Tips in Dxx05-PT (on page 42) for more

information.

De-Embedding Probes

Teledyne LeCroy probes are calibrated at the factory using a Vector Network Analyzer (VNA) to

measure a system (probe plus test fixture) frequency response. The test fixture is de-embedded

from the measurement using Teledyne LeCroy's Eye Doctor tools so the remaining frequency

response is due to the combination of the test signal and the probe loading on the test circuit. The

system frequency response is then calculated for these remaining circuit elements.

Since the WaveLink probe impedance is high, the effect of probe loading is greatly reduced and the

impact on circuit measurement is much lower than when using a probe with lower impedance.

However,if you wish to de-embed the effect of probe loading on your circuit, you can also use

Teledyne LeCroy’s Virtual Probe option. This option allows you to select the probe tip from a list of

supported tips. Your selection applies a corresponding s-parameter file that is derived from the

equivalent circuit model of the tip.

WL-HBW-A-OM-E Rev B

Handling the Probe

The WaveLink series probe is a precision test instrument. Exercise care when handling and storing

the probe. Always handle the probe by the platform/cable assembly. Avoid putting excessive strain

on any cable or interconnect lead or exposing the probe cables to sharp bends.

ESD Sensitive: The tips of the probe are sensitive to Electrostatic Discharge (ESD). Avoid

causing damage to the probe by always following anti-static procedures (wear wrist strap,

etc.) when using or handling the probe.

Solder-in Tips: Prevent damage to the solder-in tips by carefully storing them in the

plastic protective storage case when not in use.

Positioner Tip: The PT tips are very small and are fragile. When not in use, store in the

provided case.

Connecting the Platform/Cable Assembly, Amplifier

Module, and Interconnect Lead

Follow these instructions to properly connect the main probe components.

Connecting an Amplifier Module to a Platform/Cable Assembly

Attach an Amplifier Module to the Platform/Cable Assembly by aligning the connectors of the

module with the receptacles in the platform/cable assembly and pressing the two together. Be sure

to finger-tighten the assembly by rotating the threaded collar onto the module.

Connecting the Amplifier Module to the Platform/Cable Assembly

Operator's Manual

WL-HBW-A-OM-E Rev B

Do not use pliers or any other tools to tighten the collar. Remove the Amplifier Module by

loosening the threaded collar from the module and pulling the two assemblies apart.

By design, the amplifier module works with the WL-PLINK-A or WL-2.92MM

platform/cable assembly and either the Dxx05-SI Lead or Dxx05-PT Tip .

Connecting an Amplifier Module to an Interconnect Lead

Connecting a solder-in interconnect lead to an amplifier module. The positioner tip and other leads connect

in the same manner.

Align the flat side of the lead with the flat side of the amplifier module and press together.

mechanically mate with any module, they are only compatible with a Dxx05 or

Dxx05-A. No damage results; however, performance may be reduced when switching

leads between modules, and the response is not calibrated. Be sure to only use leads

with serial numbers that match with the differential amplifier module.

 Different colors indicate different bandwidths and/or product classes. Avoid

accidental interchanging by matching the color coding of the interconnect lead tip

housing with the color of the corresponding amplifier module.

Connecting the Probe to a Teledyne LeCroy Oscilloscope

The WL-PLINK-A platform/cable assembly has been designed for use with the ProLink interface of

Teledyne LeCroy's LabMaster 9 Zi-A, WaveMaster 8 Zi/Zi-A, SDA/DDA 8 Zi/Zi-A, WavePro 7 Zi/Zi-A,

SDA/DDA 7 Zi/Zi-A, and other models that use the ProLink interface. The WL-2.92MM is for use with

the 2.92mm interface of the LabMaster 10 Zi, LabMaster 9 Zi-A, and WaveMaster/SDA/DDA 8 Zi/Zi-A

models.

Connecting a WL-PLINK-A to an Oscilloscope

Attach the WL-PLINK-A platform/cable assembly to the ProLink interface by aligning the connector

with the input connector and pushing the interface toward the instrument.

A click is heard when the probe interface latches to the test instrument. The probe also uses

thumbscrews to secure the interface to the instrument. Do not overtighten the thumbscrews.

Remove the platform/cable assembly from the instrument by unscrewing the thumbscrews and

moving the interface up and down while pulling gently until a click is heard. This click indicates the

platform/cable assembly is detached from the instrument.

Connecting a WL-2.92MM to an Oscilloscope

The WL-2.92MM Platform/Cable Assembly connection consists of a LEMO connector for power and

communication and a 2.92mm signal input connector. Make corresponding connections (LEMO,

2.92mm, via included cable) to the corresponding connections on supported oscilloscopes.

Connecting a WL-2.92MM to an Oscilloscope using the

LPA-2.92mm to ProLink Adapter

Some Teledyne LeCroy oscilloscopes utilize both ProLink and 2.92 mm inputs. In this case, a single

WL-2.92MM Platform/Cable Assembly can be used for all types of high bandwidth inputs. Use the

LPA-2.92mm to ProLink Adapter to connect the WL-2.92MM to a ProLink communication, power

and signal interface.

Connecting the Probe to the Test Circuit

For all amplifier modules and interconnect leads, positive voltages applied to the + input relative to

the – input deflects the oscilloscope trace towards the top of the screen.

Exercise care when connecting the probe to the test circuit to maintain the high frequency capability

of the probe in measurement applications. Increasing the parasitic capacitance or inductance in the

input path may introduce a ring, or slow the rise time of fast-rising signals. Any extension of the

signal path with extra wire leads, etc. adversely affects the probe's performance.

A ground connection is generally not required here. Refer to Probe Grounding (on page 27) for

more details.

Solder-in Interconnect Lead

The Solder-in Lead for the amplifier module is supplied with two pre-installed resistors, which are

intended to be soldered to the runs or pad test points on the board under test. Because the resistors

and the leads are small, this interconnect lead provides the maximum signal fidelity at the highest

frequency response.

Follow these instructions to ensure optimal response for your SI Lead.

Operator's Manual

WL-HBW-A-OM-E Rev B

SI LEAD ATTACHMENT WITH PROPER STRESS RELIEF

Using a small soldering iron tip, attach the free wires of the resistors to the appropriate test points

by carefully following the directions in the following sections.

The resistors are small in order to maintain high-frequency performance. However, they

are not sturdy enough to bear the weight of the probe module. It should be supported by

other means.

A positioning tool, such as the Platform/Cable Assembly Mounting Clamp, the Probe Tip Retaining

Clip, or EZ Probe positioner can be used to support the probe.

NOTE: The tip clip helps secure and reinforce the SI resistive tips. Best practice is to consistently

position the tip at the correct angle to the device under test which it is connected. Refer to Proper SI

Lead Positioning for more information. The solder-in lead provides better signal fidelity

performance with high frequency signals if it is elevated in this manner. The tip clip also helps to

secure and reinforce the SI resistive tips, and can position the resistor leads when soldering the

resistors to the test points.

SI LEAD BENDING AND SOLDERING PROCEDURE

Properly bending the SI Lead tips results in a more consistent response. Upon first receiving your

SI Lead, the tips are not likely to be positioned for optimal performance when soldered to your

trace.

The goal is to get the resistor bodies to be parallel and the tips bent to sit on the test board traces.

1. Bend the resistor bodies to position them parallel.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

2. Bend the tips in toward the center. Make the bend as close to the resistor body as possible.

Bend them to about 60° from straight.

3. At this point, the leads can be bent out from their midpoints (making them parallel to each

other).

4. Perform a final check to ensure proper lead spacing and compare them to the trace spacing

on the PCB.

Operator's Manual

WL-HBW-A-OM-E Rev B

PROPER SI LEAD POSITIONING

When wires are attached to a probe's tips or leads to make probing of the circuit under test easier

to perform, additional inductance and/or capacitance is added to the input, lowering the resonance

frequency of a series resonance circuit, which may cause oscillations with frequencies within the

passband of the probe. These effects, or excessive ringing, degrade the performance of the probe,

resulting in incorrect presentation of the input signal, reduced bandwidth, and changes in loading

impedance.

Measuring with SI Interconnect Lead

NOTE:

 The entire SI tip should be positioned with the resistor side upright facing (away from the

PCB plane).

 Keep a 45 degree angle between the SI tip ends and the PCB plane.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

Positioner Tip (Browser)

The Dxx05-PT Positioner Tip (Browser) has a very small form factor with very low mass. It is a good

all-around browsing or mounted solution for probing in areas with a high concentration of test

points or limited free space to fit a probe.

Various attachments and extenders are supplied with the Positioner Tip, allowing it to be easily held

while browsing or connected to a mounting device.

Wand

Tripod

EZ-Probe Mount

Using these attachments, the tip can be positioned in many different ways to make probing possible

in tight geometries.

Rotating the thumbwheel adjusts the tip spacing from 0 to 3.5 mm (0 to 0.14") in a direction

perpendicular to the thumbwheel rotation. There is a positive stop on the thumbwheel to prevent it

from being rotated too far in either direction.

The tip is a pogo-pin assembly and is spring-mounted to accommodate 0.55mm of Z-Axis

compliance. This aids in applications where more than one Dxx05-PT tip is required to make

measurements in a crowded area and the tips need to be mounted at an angle to the board under

test.

Avoid applying excessive lateral pressure on the tip as breakage may result. Do not use the tip to

scrape the circuit. If the tip does break, it may be replaced in the socket. If the socket also breaks, a

Operator's Manual

WL-HBW-A-OM-E Rev B

new socket can be soldered onto the tip.See Replacing Spring-Loaded Tips and Tip Sockets on the

Positioner Tip (on page 1) for instructions on replacing tips and sockets.

Probe Grounding

In most cases, when the common mode portion of the signal consists mainly of lower frequencies,

the probe does not need to be connected to the ground of the circuit under test. This minimizes the

effects of ground loop currents. Any signal corruption caused by not having the probe connected to

ground of the signal under test is common to both inputs and is rejected by the differential

operation of the probe.

However, in an environment with high RF ambient noise, it may be better to connect the probe

ground lead to a good RF ground near the point where the signal is being measured. Find out if a

ground lead is necessary by making a measurement with and without a ground lead. Use the one

that provides the least signal corruption.

Capacitive coupling from AC mains may cause truly floating devices (like battery operated devices)

to exceed the common mode range. In such cases it is recommended to connect the probe ground

to the device under test.

 Circuits powered from laboratory bench power supplies normally have floating

outputs.

 Floating circuitry may exceed the common mode input voltage, causing damage to

the probe. Always use a ground lead when testing floating circuits.

Positioning of the Input Leads

Normally the performance of the Solder In Lead and Positioner Tip Browser is not affected by the

position of the amplifier module. They can be mounted straight upright or on an angle. However,

when it is necessary to mount the module parallel to the board, the maximum performance is

obtained when the + sign (printed near the positive input on both the SI Lead and the PT Tip) is

upward facing.

NOTE: The flexible cable connecting the input tip to the amplifier module is reasonably insensitive to

placement, but can be affected by large signal emitters on the device under test, so avoid placing it

near these types of signals

AutoColor ID and Power Control Indicators

The AutoColor ID LED, built into the platform/cable assembly, indicates various states of the probe-

oscilloscope combination:

AutoColor ID

When the probe is connected to a Teledyne LeCroy X-Stream oscilloscope, the LED illuminates in the

default color of the channel to which the probe is connected.

Platform/Cable Assembly Compatibility

When the probe tip module is compatible with the platform/cable assembly to which it is

connected, the green LED illuminates for about one second after the probe is connected to the

oscilloscope.

Conversely, when the probe tip module is incompatible with the platform/cable assembly, the red

LED illuminates—for example, when a Dxx05 amplifier is connected to a WL-PLINK instead of a WL-

PLINK-A.

Operator's Manual

WL-HBW-A-OM-E Rev B

AutoZero

WaveLink probes incorporate an AutoZero function to remove any DC offset from the probe. This

function is available when the probe is used with Teledyne LeCroy's X-Stream oscilloscopes, and

must be invoked by the user.

After several minutes of warm-up, or when the probe is exposed to a large shift in ambient

temperature, some DC offset may occur, and an AutoZero cycle should be initiated.

Start an AutoZero cycle by removing the probe from the circuit under test and touching the on-

screen AutoZero button to remove output offset drift.

Accessory Use

A variety of accessories are provided with the probe and platform/cable assembly. These

accessories help keep the probe tip in place and provide deskew capabilities or are simply common

replacement parts.

Positioning Tools

Freehand Probe Holder

The FreeHand Probe Holder (PACC-MS001) is provided as a standard accessory with the WL-PLINK-

A-CASE and WL-2.92MM-CASE. It is designed to keep most of the weight on the probe tip preventing

loss of contact with the circuit under test. The FreeHand Probe Holder is a stable, quick and easy-to-

set-up probe positioner, improving your ability to concentrate on the measurement by not having to

hold the probe.

EZ Probe Positioner

The EZ Probe Positioner is available as an optional accessory. It provides stable, accurate positioning

in the X-Y-Z Axes.

The unique 3:1 motion reduction joystick allows simple, precise positioning of the attached probe in

both the horizontal and vertical measuring plane. The probe has a fully-articulating arm, providing

30 cm (12 inch) reach in virtually any direction.

The XYZ joystick has separate friction controls allowing independent X-Y plane or Z-Axis movement

and is especially useful when combined with the Positioner Browser Probe Tip.

The EZ-Probe Positioner comes with a vacuum mounted base to keep the probe in place in any test

environment. However, the solid base is heavy enough that the positioner can be used without the

vacuum.

Long Interconnect Extender

The Long Interconnect Extender (provided with Dxx05-PT-KIT) is used to connect the probe to the

EZ-Microtech Positioner Arm. Attach the probe by first removing the screws holding the top plate to

the V-shaped probe holder. Rest the long interconnect extender in the V-shaped groove, and fasten

the top plate to the holder, using the removed screws (as follows). Then, insert the Dxx05-PT onto

the long interconnect extender.

Positioner Tip mounted to EZ Probe Positioner and Long Interconnect Extender

NOTE:

 Do not overtighten the screws.

 There is no fine adjust on the EZ probe. It is easy to exceed the Z-Axis compliance rating of

the PT. Use care when positioning the PT with the EZ probe.

Once the probe has been attached, loosen the knob on the EZ positioner arm and position the probe

close to the test point. Tighten the knob and use the joystick to fine position the probe.

Dxx0-PT-XYZ-Positioner

This positioner is a small, lightweight device that can be affixed to the printed circuit assembly using

the included adhesive pads. The black adhesive pads are for more permanent attachment, whereas

the white adhesive pads leave less residue when removed. The wide variety of short, long, swivel,

and right angle interconnect parts can be connected to the top assembly, which can then be moved

up and down along the Z-Axis to increase or release pressure on the probe points. The bottom

assembly contains a tightening wheel which can be loosened to allow minor X-Y Axis adjustments,

and then tightened to fix the exact probing position.

WL-HBW-A-OM-E Rev B

FASTENING THE CLIP TO THE BOARD

Fasten the clip to the board by removing the small piece of protection paper from one side of the

adhesive pad and mount the pad to the underside of the clip. If necessary, use alcohol to clean the

section of the board where the clip is mounted to remove any grease or flux residue.

Connecting the SI Module Using the Tip Retaining Clip

Remove the protective paper from the other side of the adhesive pad and mount the clip to the

desired location on the board. Apply pressure to the clip for at least several seconds to assure

proper adhesion (shown previous)

The adhesive pad with the tab is still visible and stays attached to the adhesive pad. The tab is used

to remove the clip from the board.

NOTE: Maximum strength of the adhesive pad is obtained after about 30 minutes.

MOVING AND POSITIONING

Always apply pressure to the pad (as follows) to prevent any shifting while bending the arms and/or

moving the probe adapter portion of the clip (typically done while positioning or attaching the

probe).

NOTE: This is especially important if moving and positioning before the adhesive pads have properly

cured.

Probe Deskew Fixtures

The Probe Deskew Fixture (PCF200) is provided as a standard accessory with WaveLink series

Platform/Cable Assemblies.

For WaveLink probes designed to accommodate all WaveLink tips (not at full bandwidth), the fixture

may be used as a convenient way to deskew several probes/oscilloscope channels. This can be

accomplished in the following ways:

 Connect a fast edge to one or both inputs. Connect the probe tip(s) to the appropriate

connection point. Solder-in probe tips and browser tips may be inserted under the

clamping mechanism. Display the probe signals on the oscilloscope screen and use the

channel deskew adjust to align them to a common point.

 Connect the WavePro/SDA/DDA 7 Zi/Zi-A, WaveMaster/SDA/DDA 8 Zi/Zi-A, or

LabMaster 9 Zi-A fast edge output to one of the inputs. Set the oscilloscope to trigger on

the internal Fast Edge source.Set the trigger delay to zero. Now, on the vertical dialog,

use the Probe Cal - Cable Deskew button to align one signal/channel at a time to the

specified zero delay trigger point (center of screen). Repeat for as many probes as you

have connected, each time aligning them to the common point.

NOTE: The Probe Deskew fixture has an inherent rise time limitation of ~70ps. Deskew of very high

frequency signals using WaveLink High Bandwidth Differential Probes may require a faster rise time

than this fixture can provide. In this case, utilize one of your signals as a reference point, and then

deskew all additional signals to the reference signal.

TF-DSQ Fixture Accessory

A TF-DSQ fixture is available as a Teledyne LeCroy accessory. The product is used in conjunction with

the oscilloscope software to perform probe deskew and DC calibration. A manual explaining the

operation of the TF-DSQ is available for download from teledynelecroy.com.

Care and Maintenance

Cleaning

The exterior of the probe and cable should be cleaned, using a soft cloth moistened with water. The

use of abrasive agents, strong detergents, or other solvents may damage the exterior of the probe.

The probe case is not sealed and should never be immersed in any fluid.

Replacing Damping Resistors on the Solder-in

Interconnect Lead

The external damping resistors locate the tip resistance as close to the device under test as possible,

which minimizes tip inductance and capacitance and provides very favorable loading characteristics.

However, these resistors are subject to mechanical stress and may periodically need to be replaced

even if proper stress-relief precautions are taken. Replacement damping resistors are included with

the probe, and replacement of these resistors is simple. Resistors are pre-cut to the right lead

lengths, so all that is required is removal and attachment of the new resistor.

Follow these steps to correctly remove the damaged damping resistors and to solder a new resistor

to your tip. It is assumed that the person performing the resistor replacement is familiar with fine

pitch soldering techniques.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

1. Remove the old resistor tip and any remaining solder from the long solder pad using a fine tip

soldering iron taking care not to de-solder the SMT resistors.

2. Use a soldering iron to pre-tin the pad. Wash the area with isopropyl alcohol to remove any

residual flux.

3. Align the damping resistor lead with the end of the tin pad and solder in place running the

lead along the pad and over the via. Avoid using excessive amounts of solder. Use the

photographs in this topic as a reference for the proper amount of solder.

Correctly Replacing Carbon Composite Resistive

Pogo-Pin Tips in Dxx05-PT

Keep the following in mind regarding Pogo Pin tips replacement, care, and use:

 The Pogo-Pin Tip pair must have a matched resistive value. If one breaks, and the

replacement has a different resistive value (likely if they are from different lots), then the pair

must be replaced . See Setting Matched Replacement Pogo-Pin Tip Ω Values Using the

Dxx05-PT Pogo-Pin Replacement Software Utility section for details.

 Don't remove your Pogo Pin tips from the socket for non-use or storage. Only remove them

when replacement is necessary.

 Never use probe tips as scraping tools.

 New carbon fiber tip technology enables low-loading, high-bandwidth measurements. Do not

over compress.

 When applying probe to test points only use light pressure. Take care not to apply pressure

exceeding throw of precision pogos.

Occasionally check the overall resistance of the center conductor on the small solder mount push-on

(SSMP) to the tip itself. The side to side resistance should be within 30 Ω of each other.

Setting Matched Replacement Pogo-Pin Tip Ω Values Using the

Dxx05-PT Pogo-Pin Replacement USB Stick Software Utility

The carbon-composite pogo-pin tips in the Dxx05-PT Positioner Tip browser are a resistively

matched set. Proper performance of this tip requires the resistive values of the pogo-pins are of a

known, matched value.

At original shipment of a Dxx05-PT Positioner Tip browser, two carbon-composite pogo-pins are pre-

installed in the positioner tip and two additional spare pogo-pins are also provided. These spare

pogo-pins are resistively matched with the pre-installed pogo-pins, so if these specific spares are

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

used to replace a broken pogo-pin, no additional activity is necessary (other than mechanical

replacement).

However, if spare pogo-pin tips are separately ordered, their resistive values are possibly

unmatched to the originals. Therefore, Teledyne LeCroy supplies a USB memory stick containing a

Dxx05-PT Pogo-Pin Replacement software utility along with the spare pogo-pins.

So, when the spare tips originally supplied with the Dxx05-PT are consumed, pogo-pins should only

be mechanically replaced with pogo-pin tips having matched values, and the Dxx05-PT Pogo-Pin

Replacement software utility must be run after replacement.

NOTE:

 Tips from different lots or vials (a vial, Dxx05-PT-TIPS, is included with your Dxx05-

PT) should not be intermixed with tips from other lots or vials.

 The Dxx05-PT Pogo-Pin Replacement Software Utility is provided on a USB Stick with

a newly-purchased Dxx05-PT Positioner Tip Browser. The utility is also available for

download at teledynelecroy.com.

Connect your USB Stick to your instrument and view the contents. Copy the Utility Program to the

desktop of your oscilloscope, and then double-click/run the program.

2. Now, start the oscilloscope application by touching the desktop shortcut.

3. Connect the Platform/Cable Assembly of your Positioner Tip Browser to the upper-row

Channel 1 oscilloscope input using the LPA-2.92 mm to ProLink Probe Adapter.

Confirm your Probe dialog is shown as part of the Channel 1 dialog.

4. Provide the PT Tip Resistance value. The label on the vial containing your replacement pins

shows this resistance value.

5. Click the Program Probe button to proceed with your tip reprogramming. When the Status

message shows DONE!, the reprogramming procedure has finished.

Functional Test

Functional Test Overview

The functional test can be used to verify the basic operation of the WaveLink Differential Probe

functions, using a Teledyne LeCroy X-Stream oscilloscope. Refer to the oscilloscope's online help for

proper use of the touch screen and controls.

Test Setup

Use the following steps to set up the basic tests:

1. Connect an amplifier module to a platform/cable assembly (for example, a D1605-A to a WL-

PLINK-A), and then connect an interconnect lead to the amplifier module. Then connect the

platform/cable assembly to channel 1 of the oscilloscope. The instant the probe is connected

to the oscilloscope, the AutoColor ID LEDs should illuminate GREEN for less than 1 second

indicating the probe is compatible with the oscilloscope.

2. After the green LED indication, the Probe AutoColor ID indicators illuminate in the color of the

channel to which the probe is connected. Verify the probe AutoColor ID indicates the proper

corresponding channel color by disconnecting the probe and reconnecting to the other

channels. Reconnect the probe to Channel 1.

3. Turn on the channel corresponding to the connected probe.

4. Touch the probe-connected channel's trace label. The Cx Vertical Adjust dialog is shown.

Verify the probe model. The D1605, is shown (previous).

5. Touch the D1605 indicator tab to show the D1605-A probe dialog as follows:

Channel trace descriptor label and Probe dialog contains data corresponding with

your attached probe.

6. Touch the Power On checkbox to verify the AutoColor ID LEDs on the probe is OFF (and

probe power is OFF). Turn the power back ON by clicking the checkbox again.

7. Touch the Led On checkbox to verify the probe's AutoColor ID LEDs turn off (probe power is

still ON). Turn LEDs back ON.

NOTE: TTL is processed internally (and the Aux Output dialog shows a TTL checkbox) for the

following oscilloscope models: WaveMaster 5000, 6000, SDA 4000, 5000, and 6000.

11. Set the amplitude to 1 Volt, Frequency to 1.00 kHz.

12. Verify the screen indicates the proper settings in the Aux Output fields.

13. Set the probe sensitivity to 200 mV/div.

Connect the + tip of the interconnect lead module to the center connector of the calibrator

output signal, and the – lead to the shell (ground) of the connector. If necessary, readjust the

tip spacing.

WL-HBW-A-OM-E Rev B

14. Verify the screen shows a square wave (you may need to adjust the channel offset). Refer to

the following screen-shot. If no square wave is shown, the + channel of the probe may be

faulty.

16. Make desired adjustments to your oscilloscope settings and obtain a stable display.

17. Adjust the tips so both touch or are almost touching.

18. Connect both tips to the calibrator output signal.

19. Verify a straight line is shown centered on the screen. There should be no vertical deflection,

to indicate good CMRR.

20. One of the channels may be at fault if a square wave or part of a square wave is shown.

This concludes the functional tests of the WaveLink High Bandwidth Differential Probe.

Performance Verification

Performance Verification Overview

This procedure can be used to verify some of the warranted characteristics of the WaveLink

Differential Probe.

The recommended calibration interval for differential probes is one year. Test results can be

recorded on a photocopy of Performance Verification Test Record (on page 70) provided at the end

of this manual.

Performance Verification can be completed without removing the probe covers or exposing the user

to hazardous voltages. No adjustments are provided.

In the unlikely event a probe fails performance verification, it can be sent back to the local service

center or the factory. For information on returning the probe, refer to the Returning a Product for

Calibration or Service (on page 46) or Returning a Product to a Different Country (on page 48)

topics as needed.

This procedure tests the WL-PLINK-A or WL-2.92MM with a D1305-A, D1605-A, D2005-A, or D2505-

A. All probe setups are tested at the factory for the following warranted specifications:

 Output Zero

 Low frequency attenuation accuracy at low and high voltage range

 Rise time

The rise time specification has dependency on characteristics of the platform/cable assembly.

Therefore, traceable calibration requires verification with a specific platform/cable assembly

denoted by serial number. The rise time and attenuation accuracy parameters of probe tip modules

utilizing detachable tips have similar dependencies on the individual interconnect lead, which is

serialized. This applies to the D1305-A, D1605-A, D2005-A, and D2505-A amplifier modules:

 The rise time specification for the D1305-A and D1605-A are valid with either the WL-PLINK-

A or WL-2.92MM platform/cable assembly provided that they were calibrated together at the

factory at time of shipment.

 The rise time for the D2005-A and D2505-A is valid with the WL-2.92MM platform/cable

assembly that was provided at time of factory shipment. Due to the high BW and short rise

time of the probe system, very specialized test equipment and procedures are required for

performance verification of the rise time, and return to a factory service center is required.

Operator's Manual

WL-HBW-A-OM-E Rev B

Output zero and attenuation accuracy can be measured in the field and verified with any

platform/cable assembly.

If the probe package includes multiple probe interconnect leads, the best practice is to complete the

entire procedure for each probe interconnect lead. If more than one interconnect lead is being

verified, copy and fill out a separate test record for each platform/cable assembly, amplifier module,

and interconnect lead.

If the probe package includes probe interconnect leads that are not serialized to the amplifier

module and platform/cable assembly, then performance may not be verifiable.

NOTE: It is recommended that the Functional Check be performed prior to the Performance

Verification Procedure to assure all other non-warranted functions perform as specified. See Quick

Functional Check (on page 68) for more information.

Required Test Equipment

The following table lists the test equipment and accessories, or their equivalents, required for

performance verification of the WaveLink Series of High Bandwidth Differential Probes.

The procedure has been developed to minimize the number of parameters requiring calibration in

the test instrumentation. Only the parameters listed in boldface in the Minimum Requirements

column must be calibrated to the accuracy indicated.

Because the input and output connector types may vary on different brands and models of test

instruments, additional adapters or cables may be required.

Operator's Manual

WL-HBW-A-OM-E Rev B

Preliminary Procedure

WaveMaster 8 Zi /Zi-A oscilloscopes contain ProBus, ProLink, and 2.92mm (on ≥20 GHz models)

inputs, which conveniently allows this test to be performed on the oscilloscope that is used with the

probe. However, other Teledyne LeCroy oscilloscopes with ProBus , ProLink, or 2.92mm inputs may

also be used, since these inputs are only providing power to the probe during testing. The following

instructions are for using a ProLink interface connection for the verification of a WL-PLINK-A. For

verification of a WL-2.92MM, the WL-2.92MM and LPA-2.92 may be substituted instead for the WL-

PLINK-A and ProLink CF01, respectively.

1. Connect the WL-PLINK-A to the input of ProLink-CF01 Calibration Fixture.

2. Remove the captive screws from the ProLink-CF01, allowing the WL-PLINK-A Calibration

Fixture connectivity.

NOTE: There are no captive screws to remove on the WL-2.92MM.

3. When testing using a WL-PLINK-A, connect the output of the ProLink-CF01 Calibration Fixture

to a free channel of the WaveMaster 8 Zi or 8 Zi-A oscilloscope.

4. Allow at least 20 minutes warm-up time for the WaveLink high bandwidth probe and test

equipment before performing the Verification Procedure.

5. Turn on the other test equipment and allow them to warm up for the manufacturer's

recommended timeframe.

6. While the instruments are reaching operating temperature, print a copy of Performance

Verification Test Record (on page 70), and fill in the necessary data.

Most of the warranted characteristics of the WaveLink Differential Probe are valid at any

temperature within the Environmental Characteristics portion of the Specification. See

teledynelecroy.com for specification details. However, some of the other test equipment used to

verify the performance may have environmental limitations required to meet the accuracy

requirements needed for the procedure. Be sure that the ambient conditions meet the

requirements of all the test instruments used in the procedure.

As specified, the low frequency attenuation accuracy is valid at a reduced temperature range from

20 to 30° C; verification, therefore, must be done at an ambient temperature within that range.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

Verification Procedure

This verification procedure describes the tests, using a probe with an SI interconnect lead attached.

Note that the interconnect lead does not need to be attached for this procedure.

The setup and procedure for testing Output Zero and Attenuation Accuracy is the same for WL-

PLINK-A as for WL-2.92mm, except for a different oscilloscope input connection.

Output Zero

1. Connect the appropriate calibration fixture to the output of the probe to be tested (shown in

the following figure).

NOTE: The output zero is not affected by the input leads, so any interconnect lead may be

used for this test.

2. Provide power to the probe by connecting the ProLink-CF01 to any ProLink input of a

WaveMaster 8 Zi /Zi-A oscilloscope. If connecting to a 2.92mm input, use the appropriate

devices, as described in the Preliminary Procedure (on page 61).

3. No signal input connection to the oscilloscope is required for the Output Zero test.

4. For the WL-PLINK-A, connect a BNC-to-SMA adapter to the SMA output connector of the

ProLink-CF01 Calibration Fixture. Then, connect the BNC end to a BNC Tee (shown in the

following figure).

For the WL-2.92MM, connect a BNC to 2.92MM adapter to the 2.92mm output connector of

the LPA-2.92 Calibration Fixture.

5. Connect the Precision 50 Ω Terminator, using another BNC cable, to the free end of the BNC

Tee.

6. Set the DMM to DC volts.

7. Connect the Precision 50 Ω Terminator to the DMM input.

8. After a warm-up time of at least 20 minutes, measure the output voltage and record the

result on the Performance Verification Test Record (on page 70) as Output Voltage

(step 1).

Operator's Manual

WL-HBW-A-OM-E Rev B

Output Zero Voltage

9. Initiate an AutoZero.

10. Wait an additional 15 minutes, then record the DMM reading to 1 mV resolution on the

Performance Verification Test Record (on page 70) as Output Voltage after AutoZero

(step 2).

11. Take the difference of the two readings recorded steps 8 and 10 (previous) and multiply by

the Effective gain value shown in the channel attributes when the probe is attached. See

Operation with a Teledyne LeCroy Oscilloscope (on page 19) for more information.

12. On the Performance Verification Test Record (on page 70), record the result as Output

Zero (step 3).

13. Verify the absolute value of Output Zero is less than 10 mV.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

DC Frequency Attenuation Accuracy

NOTE: The low-frequency attenuation accuracy needs to be verified with each interconnect lead.

Because each interconnect lead has its own serial number, it should be recorded with the serial

number of the probe tip module on the Performance Verification Test Record (on page 70).

1. Connect the male end of a BNC Tee to the Sine Wave Generator output (refer to the

following figure for setup). Set the generator's output voltage to 0 Volts.

2. Connect one end of a BNC cable to the BNC Tee and the other end to a Female BNC-to-Male

SMA adapter.

3. Connect the male side of the BNC-to-SMA adapter to a female end of the Probe Deskew

Fixture. Refer to the following figures to determine which side of the Deskew Fixture to use

for the probe tip module and interconnect lead to be tested.

4. Connect another BNC cable to the free end of the BNC Tee and the other end of the cable to

the Female BNC-to-Dual Banana Plug Adapter.

5. Connect the Banana Plug Adapter to the DMM input, verifying that the ground side of the

adapter is connected to the low side of the DMM.

6. Attach a ProLink-CF01 Calibration Fixture to the WL-PLINK-A, or a LPA-2.92 Calibration Fixture

to the WL-2.92MM.

7. Remove the captive screws from the ProLink-CF01 allowing the WL-PLINK-A Calibration

Fixture connectivity.

NOTE: This step is not necessary with the LPA-2.92.

8. Connect the Calibration Fixture to Channel 1 of the oscilloscope. If using the LPA-2.92

Calibration Fixture, connect it to Channel 2. In either case, make sure that the appropriate

input (either A or B) is selected in the oscilloscope channel dialog box.

9. Connect a BNC-to-SMA adapter to the SMA output connector of the ProLink-CF01 Calibration

Fixture, and the BNC end to a BNC Tee (as shown in the following figure). If using the LPA-2.92

Calibration Fixture, connect a BNC to 2.92mm adapter to the 2.92mm output connector of

the LPA-2.92.

Operator's Manual

WL-HBW-A-OM-E Rev B

10. To obtain 1 MΩ input impedance on a WL-PLINK-A or WL-2.92MM, connect the male side of

the BNC Tee to a free ProBus input of a WaveMaster 8 Zi /Zi-A oscilloscope. Make sure the

connected channel has the correct B input selected in the oscilloscope channel dialog box.

11. This input is used to observe the probe's output signal in order to verify adequate Deskew

Fixture contact.

WL-PLINK-A or WL-2.92MM with an SI Lead Measuring Input Voltage

13. Connect the Precision 50 Ω Terminator via another BNC cable to the free end of the BNC Tee.

14. Leave the unused end of the Precision Terminator floating for the time being.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

15. Select the channel to which the BNC tee is connected and set the channel's sensitivity to 0.1

V/DIV. Verify that the input coupling is set to DC and the input resistance to 1 MΩ. Do not

terminate the BNC Tee adapter into 50 Ω.

NOTE: The following step and figure show how to connect the interconnect lead to the deskew

fixture.

Connecting SI Interconnect Leads to the Fixture

SI to Deskew Fixture Connection

1. The SI leads should be connected with the ends of the damping resistors placed under the

clip. Be sure to press down on the plastic tab to lift the clip and slide the wires under the clip,

verifying the + side is located over the center strip and the – side over the ground plane on

either side of the center strip. Release the tab. Set the DMM to read AC.

2. Set the sine wave generator to about 70 Hz and the output 0.8 Vp-p (0.282 Vrms), as indicated

on the DMM.

3. If necessary, adjust the SI tip in the fixture so the tips make good contact to get the proper

amplitude (about 4 divisions) on the oscilloscope.

4. With good probe tip contacts verified, record the DMM reading to 1 mV resolution on the

Performance Verification Test Record (on page 70) as Probe Input Voltage (step 4).

5. Unplug the BNC to Banana Plug Adapter from the DMM and connect the Precision 50 Ω

Terminator to the DMM input (shown as follows).

Operator's Manual

WL-HBW-A-OM-E Rev B

6. After the DMM has stabilized, record the reading to 1 mV resolution on the Performance

Verification Test Record (on page 70) as Probe Output Voltage (step 5).

7. Take the probe's attenuation into account by multiplying the reading recorded 3 steps prior

(for Probe Input Voltage) by the Effective gain value shown in the channel attributes when

the probe is attached. See Operation with a Teledyne LeCroy Oscilloscope (on page 19)

for more information.

8. On the Performance Verification Test Record (on page 70), record the result as

Corrected Output Voltage (step 6).

9. Divide the Output Voltage (obtained 2 steps prior) by the Input Voltage (obtained 4 steps

prior). Subtract the ratio from 1.0 and multiply the result by 100% for the error percentage.

10. On the Performance Verification Test Record (on page 70), record the result to two

decimal places (±0.xx %) as Probe Attenuation Error (step 7).

11. Ensure the calculated Probe Attenuation Error is less than ±2%.

This concludes the Performance Verification Procedure.

Quick Functional Check

This test is a simple, interim check to ensure your WaveLink High Bandwidth Differential Probe is

generally functioning and hasn't experienced any significant performance changes. This test should

be run after potentially damaging stresses are applied to the probe and check if the probe is still

functional. It can be used for any WaveLink Model (D1305-A, D1605-A, D2005-A, D2505-A, etc.); the

Description

Minimum Requirements and/or Test Equipment

Examples

WaveLink High Bandwidth Differential

Probe

With ground lead and grabber (484010043 and 594200003).

Oscilloscope

WaveMaster, DDA, or SDA 8 Zi / Zi-A model or better.

Probe Deskew Fixture

Part number PCF-200.

50Ω SMA(m) Termination

42402730003 (Mini-Circuits ANNE-50+ or equivalent).

Use the same setup as for the Verification Procedure (on page 62).

1. Connect the WaveLink High Bandwidth Differential Probe to the oscilloscope input channel.

Make sure the probe is recognized by the oscilloscope and the platform LED channel color

matches.

2. Connect the Probe Deskew Fixture (part number PCF-200) to the Fast Edge output of the

oscilloscope. Connect the 50Ω termination to the SMA(f) output of the deskew fixture.

3. Connect the SI Probe tip to the PCF-200 fixture verifying that the positive lead is connected to

the fixture trace, and the other lead is connected to the fixture ground. Connect the ground

lead to the fixture ground (reference the previous figure in the Connecting SI Interconnect

Leads to the Fixture topic for details).

4. Set the channel on the oscilloscope to:

 100 mV/div

 0V offset

 10 ns/div

 Sinx/x averaging 16 sweeps

 Measure the amplitude and rise time of the signal

5. Check that the amplitude is about equal to 350 mV (within 20 mV) and the rise time is less

than 60 ps. The first time you test a probe, you can save the trace to memory for test

comparisons at a later date.

6. You might also want to save the screen to a file.

NOTE: The fast edge doesn't have a very flat response, and the deskew fixture is not designed for

such high bandwidth, so the aberrations seen here are mostly determined by the source and not the

probe.

Probe Input Impedance and Loading

Attaching any probe to a test circuit adds some loading to the circuit under test. In most applications

the high impedance of the probe, compared to the impedance of the circuit under test, imparts

insignificant load to the test circuit. However, at very high frequencies the capacitive reactance of

the Probe Tip Module or Interconnect Lead may load the circuit enough to affect the measurement.

These probes are designed to minimize these effects at high frequencies. The SI Interconnect Lead

tip uses a construction in which the tip termination consists of a damping resistor with very short

lead length (to minimize inductance) that is soldered to the circuit. These damping resistors connect

to a special distributed resistor on the lead. The distributed resistors compensate for the inherent

transmission loss of the probe system. The result is very broad frequency response with relatively

high impedance. Refer to the figures in this topic for equivalent input circuit information.

These circuits represent the aggregate load placed on the test circuit, but not the actual input circuit

of the probe. For critical applications, you can enter the information of your module or lead into

SPICE or some other simulator to accurately represent the probe loading.

NOTE: To avoid degrading the high frequency performance of the probe do not extend the input

leads on the solder-in interconnect lead tip.

Differential Mode and Common Mode

Differential probes sense the voltage difference which appears between the + input and – input.

This voltage is referred to as the Differential Mode or Normal Mode voltage. The voltage component

which is referenced to earth and is identical on both inputs is rejected by the amplifier. This voltage

is referred to as the Common Mode voltage and can be expressed as:

Differential Mode Range and Common Mode Range

Differential Mode range is the maximum signal that can be applied between the + and - inputs

without overloading the amplifier/amplifier, which otherwise would result in clipping or distorting of

the waveform measured by the oscilloscope.

The Common Mode Range is the maximum voltage with respect to earth ground that can be applied

to either input. Exceeding the common mode range can result in unpredictable measurements.

Because the Common Mode signal is normally rejected, and not displayed on the oscilloscope, the

user needs to be careful to avoid accidentally exceeding the common mode range.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

Because the input signal of a differential amplifier is not referenced to ground, the concept of Vpeak

versus Vpeak-peak may be confusing.

With a ground referenced signal, Vpeak is the maximum instantaneous voltage amplitude the signal

will have with respect to ground. In a differential system, there is no ground reference. Therefore,

the Differential Mode Range refers to the maximum instantaneous amplitude of the signal

difference between the positive input and the negative input. Since most amplifiers have

symmetrical bipolar inputs, the value is generally expressed as an absolute value, and can have

either polarity.

For example, an amplifier with a differential mode rating of ±1 V can have a maximum voltage

difference appearing at any instant in time of 1 V between the inputs. The polarity could be either

positive or negative. However, this does not imply that the number can be doubled to 2 volts. For

clarity, consider the following table of absolute voltages applied to the inputs of a WaveLink D1605

differential amplifier that has a differential mode range or ±800 mV and a common mode range of

±4 V:

Some amplitude is specified as peak to peak. The differential amplifier peak-to-peak range is twice

the peak differential mode range specification (at any instant in time) as the maximum voltage

amplitude signal is one-half of the peak-to-peak value.

In a balanced differential system, the signal on each output is an inverted copy of the other input.

For example, an LVDS system may have a pair of outputs, each of which has a voltage swing of 0 to

+370 mV. A logic 1 would be represented when the + output is at +370 mV, while the - output is at 0

V. A logic zero is the opposite polarity: the + output at 0 V and the - output at +370 mV. Note that

Operator's Manual

WL-HBW-A-OM-E Rev B

even though both outputs swing 370 mV, the maximum difference voltage between them at any

instant is still within ±370 mV. So, this signal could be measured with a differential amplifier that has

a differential mode range of ±400 mV.

Common Mode Rejection Ratio

The ideal differential probe/amplifier would sense and amplify only the differential mode voltage

component and reject the entire common mode voltage component. Real differential amplifiers are

not perfect, and a small portion of the common mode voltage component appears at the output.

Common Mode Rejection Ratio (CMRR) is the measure of how much the amplifier rejects the

common mode voltage component. CMRR is equal to the differential mode gain (or normal gain)

divided by the common mode gain. Common mode gain is equal to the output voltage divided by

the input voltage when both inputs are driven by only the common mode signal. CMRR can be

expressed as a ratio (e.g., 10,000:1) or implicitly in dB (e.g., 80 dB). Higher numbers indicate greater

rejection (better performance).

The first order term determining the CMRR is the relative gain matching between the + and – input

paths. Obtain high CMRR values by precisely matching the input attenuators in a differential

amplifier. The matching includes the DC attenuation and the capacitance which determines the AC

attenuation. As the frequency of the common mode component increases, the effects of stray

parasitic capacitance and inductance in determining the AC component become more pronounced.

The CMRR becomes smaller as the frequency increases. Therefore, the CMRR is usually specified in a

graph of CMRR versus common mode frequency.

The common mode frequency in these graphs is assumed to be sinusoidal. In real life applications,

the common mode signal is seldom a pure sine wave. Signals with pulse wave shapes contain

frequency components much higher than the repetition rate may suggest. This makes it very difficult

to predict actual performance in the application for CMRR-versus-frequency graphs. The practical

application of these graphs is to compare the relative common mode rejection performance

between different probes and amplifiers.

WaveLink Series Differential Probe (13-25 GHz)

WL-HBW-A-OM-E Rev B

Offset

The offset for the WaveLink High Bandwidth Series probes (D1305-A, D1605-A, D2005-A, and D2505-

A) is in the probe amplifier. Thus, these probes have full offset capability over their entire V/Div

range.

When the WaveLink series probe is used with a Teledyne LeCroy WaveMaster 8 Zi / Zi-A or similar

oscilloscope equipped with ProLink or 2.92mm interface, the probe offset is controlled with the

channel OFFSET knob.

Sometimes it may be desirable to display a waveform as a reference signal where a large display

amplitude may not be necessary. Perhaps a timing reference when amplitude details are not

needed. In such a case, the oscilloscope's zoom function can be used to reduce the displayed height

of the reference signal. (Refer to your oscilloscope's online help for operation of the zoom function.)

Dynamic Range

WaveLink High Bandwidth D1305-A, D1605-A, D2005-A, and D2505-A probes have no gain or

attenuation control. However, WL-PLINK-A and WL-2.92MM do provide gain and attenuation

controls.

The system attenuation is fixed at approximately 3.5 to 4.5, depending on model. The actual gain

value for each probe is indicated in the probe dialog box, which is displayed when the probe is

connected to the scope.

The WaveLink series probes are always DC coupled (no AC coupling is provided). Therefore, care

must be exercised to avoid exceeding the common mode range. Because the common mode signal

is rejected by the probe and is not displayed, changes in the amplitude of the common mode

component are not apparent to the user. Exceeding the common mode range may introduce

distortion to the probe's output signal.
