TGxx11 Series
Function/Arbitrary/Pulse generators
TG5011 & TG2511
The TGxx11 Series represents the state-of-the-art in DDS based function generators.
The 50MHz TG5011 significantly outperforms other generators in its price range,
not just because of its frequency range, but because of its all round performance
and features.
The TG2511 incorporates a similar feature set at a still lower cost and represents
exceptional value for those with lower frequency requirements.
TTi manufactures a wide range of function, arbitrary and pulse generators from
lower frequency analog units to multi-channel variable clock arbitrary generators.

Features in detail
Higher Waveform Frequencies
The TG5011 out-performs other generators in its price
range by offering both sine and square waves up to
50MHz. The lower cost TG2511 operates to 25MHz.
Exceptional frequency precision
The frequency of these waveforms can be set with up to 14 digits or one
micro hertz of resolution.
The DDS based frequency generation system uses a TCXO timebase
oscillator with a stability of 1ppm.
Waveform Quality
The TG5011 and TG2511 generate high purity sine waves with low
harmonic distortion and low phase noise. Square waves have a rise time
of below 8ns (13ns on TG2511) and low overshoot. Variable symmetry
can be used up to 25MHz.
Triangle and Ramp
High quality triangle and variable symmetry ramp waveforms are
available up to 500kHz (TG5011) or 250kHz (TG2511).
These waveforms are also available at higher frequencies via the arbitrary
function but without symmetry adjustment and with reduced waveform
quality as the frequency increases.
VLF generation
The high resolution of the DDS system means that very low frequencies
can be set. For example, a frequency of around 1mHz could be set with a
resolution of 0.1% and a stability of 1ppm.
Full Pulse Generator capabilities
Both models incorporate a pulse generator mode which
provides wide range pulse width and delay independent
of period. Rise and fall times (edge speeds) are also
fully variable.
Wide-range repetition rate
On the TG5011, the pulse period can be set between 80ns and 2000 secs.
(0.5mHz to 12.5MHz) with a resolution of 14 digits or 1µHz. On the
TG2511, the minimum pulse period is 160ns (6.25MHz).
Fully variable pulse Width and Delay
Pulse width and pulse delay can be independently set to a resolution of
10ns. Minimum pulse width is 20ns and duty cycles can be as low as one
in two billion.
Note that display screens on this page are shown at around 80% of actual size.
Independently variable Rise and Fall
The generators offer very fast edge speeds of better than 8ns on the
TG5011 or 13ns on the TG2511, but the edges can be slowed down to
simulate slower pulses.
Rise and fall times are independently variable in the range 5ns to 40us
(10ns to 40us on the TG2511), or can be linked so that both edge speeds
are the same.
Trigger, Burst and Gate
As with all other waveforms, pulses can be triggered from an external
trigger input (or manual trigger, the internal trigger generator or a Bus
command).
Burst mode creates a burst of between one and a million pulses in
response to each active edge of the trigger.
Gated cause pulses to be generated only when the gate signal is true. The
gate source can be external or internal exactly as the trigger signal.
Arbitrary Waveforms
Both generators offer DDS generated arbitrary
waveforms capability. A number of standard waveforms
are included, and up to four user defined arbitrary
waveforms can be stored in the instrument at any one time.
14 bits, 128k words, 125MS/s
Waveforms have a vertical resolution of 14 bits (16,384 amplitude levels).
Waveforms can be created using between 2 and 131,072 points (128k).
The sampling rate is 125MHz and DDS techniques are used to provide any
repetition rate between 1uHz and 10MHz (TG5011) or 6MHz (TG2511)
with up to 14 digits of frequency resolution.
Internal and External Waveform Storage
Up to four user defined waveforms totalling up to 256k words can be
stored within the permanent internal memory of the instrument.
However, a front mounted USB port enables external Flash memory
storage of up to 1000 waveforms of any size.
This memory stick also provides a quick and convenient method for
transferring waveform files to and from a PC. It can also be used for
storing instrument set-ups.
Pre-built Complex Waveforms
Commonly used complex waveforms are provided both built-in to the
instrument and for loading into the user defined waveform space.
These include sin(x)/x, exponential rise and fall, logarithmic rise and fall,
gaussian, lorentz, haversine and cardiac waveforms.
Waveform Creation & Editing
Arbitrary waveforms can be created and edited using the simple tools
built into the instrument. However, complex waveforms require an
external PC based editor.
Both instruments are supplied with Waveform Manager Plus for Windows®
which provides the most comprehensive set of waveform tools available
including a mathematical expression editor, freehand drawing, waveform
libraries, and import of waveforms using the Clip Board.
More information is provided on Page 5 of this brochure.
Standard, Pulse and Arbitrary Waveforms
Features in detail
USB Flash Drive Interface
Both instruments incorporate a front mounted USB
socket for connection of flash memory disk drives which
can store up to 1,000 waveforms and 1,000 setups.
Unlimited Waveform Storage
These drives can be used both to store waveforms permanently and to
transfer waveforms from or to a PC.
Arbitrary waveform storage within the instrument is limited to four
waveforms. Each flash drive can store up to 1000 waveforms which can
be accessed using the instruments file handling utilities.
Storage of Instrument Set-ups
Up to nine complete set-ups of the instrument can be stored within its
own non-volatile memory. Up to 1000 further set-ups can be stored on
each flash drive.
Digital Modulation, Internal & External
Both generators offer a comprehensive set of digitally
based modulations.
The internal modulation source can use any of the
standard or arbitrary waveforms currently within
the generator (including noise) thus removing the need for an external
modulation source. A modulating frequency between 1µHz and 20kHz
can be specified.
An external modulation input enables any external waveform source to
be used when required. The external bandwidth is DC to 20kHz.
AM, FM and PM
Sine, square, ramp or arbitrary waveforms can be modulated using
amplitude, frequency or phase modulation.
Amplitude depth is variable from 0.0% to 120.0%, frequency deviation
from zero to Fmax/2, and phase deviation from -360.0 to +360.0 degrees.
PWM
Pulse width modulation is available for the pulse function using any
standard or arbitrary waveform including noise. Pulse width deviation is
variable between 0% and 100%.
FSK
Frequency shift keying between any two frequencies is available for sine,
square, ramp or arbitrary waveforms using the internal trigger generator
or an external trigger signal.
The internal trigger generator is variable between 2mHz and 1MHz with
nine digit resolution.
Sweep and Burst
Sweep, Burst and Gated modes of operation are
available using either an external trigger signal or the
internal trigger generator.
Wide range Frequency Sweep
Phase continuous sweep is available for all standard and arbitrary
waveforms except for pulse. The sweep range is from 1µHz through
to the maximum for the chosen carrier waveform. Start and stop
frequencies can be set independently.
The sweep can be linear or logarithmic, triggered or continuous with
a period between 1ms and 500s. The sweep trigger can be manual or
internal from the trigger generator or external from the trigger socket or
from a remote interface command.
A marker is provided that outputs an edge synchronous with any
frequency point within the sweep.
Triggered Burst
In Burst mode, each active edge of the trigger will produce one burst of
the waveform.
The number of cycles in a burst can be set between 1 and 1,048,575 (or
infinite). The burst starts and ends at a waveform phase angle settable
between -360.0 to +360.0 degrees.
Trigger signal
The trigger signal can be manual from the front panel key, internal from
the internal trigger generator, external from the trigger-in socket, or
remote via a bus command.
The trigger-in socket has a nominal TTL threshold and can be set to +ve
edge or -ve edge triggering. The minimum trigger pulse width is 50ns.
The internal trigger generator is variable between 2mHz and 1MHz with 9
digit resolution.
Gated
In Gated mode the waveform runs only when the gate signal is true. The
start point of the waveform is settable from -360.0 to +360.0 degrees
and a the last cycle is completed after the gate signal goes false.
All of the options available for triggering are available for gating. The
trigger-in socket can be set as high or low for true.
Noise Generation
Both models can generate gaussian white noise to
a -3dB bandwidth of 20MHz. The noise generation
algorithm achieves a high crest factor (peak to rms
ratio) of 5.27.
Adding Noise to a waveform
Noise can be added to any waveform except pulse. The amount of noise
added can be specified as 0% to 50% of the amplitude of the carrier
waveform.
Modulating with Noise
Noise can be used as the modulating waveform for AM, FM, PM or
PWM modulations using any of the carrier waveforms allowable for that
modulation type.

Features in detail
Locking to Other Sources
Both the models include external reference and phase
locking as standard, unlike some competitor products
for which they are an expensive option.
External Frequency Reference
The generators use a high quality TCXO crystal as the internal frequency
reference providing 1ppm accuracy and stability.
If a higher accuracy or stability is required, an external 10MHz reference
signal (from an off-air standard for example) can be applied to the Ref.
Clock input.
Phase Locking Two Generators (or more)
Two generators can be synchronised together to provide outputs at the
same frequency (or at harmonics) and with a phase difference.
The amplitude and phase of these outputs can also be modulated
providing the capability to perform QAM and QPSK respectively.
Any waveform other than pulse can be used, and the phase difference
is adjustable between -360.0 and +360.0 to a resolution of 0.1 degrees.
Skew is better than 5ns.
It is also possible to synchronise more than two generators but the
resulting precision is not specified.
Full Remote Control
All functions of the generators can be controlled from
the digital interfaces. Arbitrary waveform data can also
be loaded using these interfaces.
An IVI driver for Windows is supplied. This provides support for common
applications such as LabView*, LabWindows* and HP-VEE*.
The LAN interface uses a standard 10/100 base-T
Ethernet hardware connection with ICMP and TCP/IP
Protocol for connection to a Local Area Network or
direct connection to a single PC.
This interface supports LXI and is the most appropriate for larger system
use because of its scalable nature.
The LAN interface is compliant with LXI (LAN eXten-
sions for Instrumentation) class C.
LXI is the next-generation, LAN-based modular
architecture standard for automated test systems
managed by the LXI Consortium, and is expected to become the successor
to GPIB in many systems.
USB provides a simple and convenient means of
connection to a PC and is particularly appropriate for
small system use. USB has effectively replaced
RS232 in many applications.
The interface uses a standard USB 2.0 hardware connection and is
implemented as virtual-COM port. A Windows* USB driver is provided.
As well as the rear mounted USB device interface connector, a front
mounted USB Host interface connector allows USB Flash memory to be
connected.
G versions of the products are fitted with a GPIB
(IEEE-488) interface. They retain both the other
interfaces, giving them even greater flexibility.

HPVEE (now Agilent VEE) is a trademark of Agilent Technologies.
* USB interface is supported for Windows 2000, XP, Vista and Windows 7.

High Waveform Quality
The high waveform quality with its low aberrations is
available over a wide amplitude range of 20mV to 20V
pk-pk emf (10mV to 10V into 50 W).
DC offset is provided independently of waveform attenuation so, for
example, a waveform amplitude of millivolts can be combined with a dc
level of volts.
Intelligent Amplitude Display
Amplitudes can be displayed as peak to peak or as RMS values, with the
rms being correctly calculated for the waveform shape. RMS values can
alternatively be specified in dBm.
If preferred values can be entered in terms of high level and low level
instead of amplitude and offset.
The amplitudes are shown relative to the selected load impedance which
is 50 W (or High-Z) by default, but can be selected as any impedance
between 1 W and 10 kW.
Multi-function Sync Output
The Sync output provides a logic level signal that
can perform a number of functions intended for
synchronisation with external equipment:
Normal Waveform Sync Modulation Sync
Burst Sync Sweep Sync (with sweep marker)
Trigger Signal Out Phase Lock (for 2nd generator)
The signal type can be selected manually or automatically dependent
upon the function in use.
Rear Panel Inputs and Outputs
In addition to the digital bus interfaces, the rear panel carries four I/O
sockets:
External Modulation Input - for AM, FM, PM and PWM external modulation.
Trigger Input - for external triggering of Burst, Gated or Sweep waveforms.
Reference Clock Input - for use with an external frequency reference or phase
locking of two generators.
Reference Clock Output - a buffered version of whichever clock (internal or
external) that the generator is using.
Waveform Manager Plus
Waveform Manager Plus is a Windows* based
application for creation, editing and management of
arbitrary waveforms using a PC
It incorporates a complete suite of tools for waveform
creation and editing including standard waveforms, mathematical
expressions and freehand drawing. Virtually any waveform can be created
using combinations of these tools.
Mathematical Expression Editor
The sophisticated mathematical expression editor allows geometric,
logarithmic and pulse functions to be combined to create exact
representations of complex signals.
Different expressions can be used for different sections of a waveform
and can be combined with imported waveforms or drawn waveforms
where mathematical representation is not possible.
Import of Other Waveforms
The program offers direct import from .csv files, the most commonly used
format for graphical description. Additionally a Clipboard import function
supports any waveform that can be described by a set of Y-axis data
points regardless of their format.
Any instrument or waveform generating program that can create a list of
Y values can therefore be accommodated. This is a highly flexible method
which can be used to create arbitrary generator waveforms from signals
captured by instruments such as oscilloscopes and network analysers, or
from software such as MathCad.

Features in detail
High Resolution LCD
The 3.6” diagonal panel uses 256 x 112 pixels and
provides a large amount of simultaneous information.
System connection information is shown on the top line. Below that is a
general status screen showing five major parameters. These parameters
change depending upon the function being used.
Below the status information is the main editing line which shows the
parameter currently under control.
Representative Waveform Display
The area the to right of the status section shows a representation of the
current waveform.
This is more than just a fixed display for each waveform, it is calculated
from the waveform parameters and gives a live indication when values
such as symmetry, rise time or pulse width are changed.
Even user defined arbitrary waveforms are shown (subject to the
limitations of the display resolution).
Modulation waveforms and representations of the modulated carrier are
shown simultaneously. Burst count waveforms are also shown graphically.
Soft Key Control
Six soft keys below the display provide access and control of the
parameters for each function.
All numeric parameters can be set directly from the numeric keypad, or
can be changed using the spin wheel.
Period entry can be chosen instead of frequency, and amplitude and offset
can be changed to Hi and Lo levels.
Frequencies can be entered in any units from uHz to MHz, periods from ns
to seconds, and amplitudes in mV or V, rms or pk-pk, or in dBm
The currently selected waveform and major functions are also indicated
by illumination of the respective keys.
Mechanical Drawings
Bench-top Operation
The generators are highly compact and use a minimum
of bench space.
Protective mouldings guard against knock damage and a multi-position
stand angles the instrument conveniently as well as providing a carry
handle.
Rack Mounting
For system applications the generators can be rack mounted.
With the protective mouldings and handle removed the size is half rack
width by 2U high.
A 2U rack mounting kit is available suitable for one or two instruments.
Display, Control, Bench/Rack Mounting
Rear panel mounts the digital interfaces and the rear I/O connectors.

Sync Out
Multifunction output user definable or automatically selected to be any of the following:
Carrier Waveform Sync: The function varies with waveform type as follows:
Sine/Ramp/Pulse - A square wave with 50% duty cycle at the waveform frequency.
Square - A square wave with same duty cycle as the main output at the waveform frequency.
Arbs - A square wave with 50% duty cycle at the waveform frequency. The sync is a TTL high when
the first point of the waveform is output. Noise - No sync associated with noise.
Modulation Sync: The function varies with modulation type as follows:

waveform when modulation source is internal, or a square wave referenced to the carrier waveform
when modulation source is external. No sync is associated with noise as the modulation source.
FSK - A square wave referenced to the trigger rate. The sync is a TTL high when hop frequency is
the output frequency and TTL low when carrier frequency is the output frequency for positive slope
and vice versa for negative slope.
Burst Sync: A square wave that is a TTL high when the burst begins and a TTL low
when burst is completed.
Trigger: Selects the current trigger signal. Useful for synchronizing burst or
gated signals.

PHASE SYNC (Phase Synchronising Two Generators)
Two generators can be synchronised together to provide outputs at the same frequency (or
harmonics) and with a phase difference.
The amplitude and phase of these outputs can also be modulated providing the capability to
perform QAM and QPSK respectively.
It is also possible to synchronise more than two generators but the precision is not
guaranteed.
