The Series 3700A offers scalable, instrument grade switching

and multi-channel measurement solutions that are optimized for

automated testing of electronic products and components. The

Series 3700A includes four versions of the Model 3706A system

switch mainframe along with a growing family of plug-in switch

and control cards. When the Model 3706A mainframe is ordered

with the high performance multimeter, you receive a tightly

integrated switch and measurement system that can meet the

demanding application requirements in a functional test system

or provide the flexibility needed in stand-alone data acquisition

and measurement applications.

Maximizes System Control and Flexibility

To provide users with greater versatility when designing test

systems, the Series 3700A mainframes are equipped with many

standard features. For example, easy connectivity is supported

with three remote interfaces: LXI/Ethernet, General Purpose

Interface Bus (GPIB), and Universal Serial Bus (USB). Fourteen

digital I/O lines are also included, which are programmable

and can be used to control external devices such as component handlers or other instruments.

Additionally, system control can be greatly enhanced by using our Test Script Processor (TSP) tech-

nology. This technology provides “smart” instruments with the ability to perform distributed process-

ing and control at the instrument level versus a central PC.

High Quality Switching at a Value Price

The Series 3700A builds upon Keithley’s tradition of producing innovative, high quality, precise signal

switching. This series offers a growing family of high density and general purpose plug-in cards that

accommodates a broad range of signals at very competitive pricing. The Series 3700A supports applica-

tions as diverse as design validation, accelerated stress testing, data acquisition, and functional testing.

Model 3706A Mainframe

The Series 3700A includes the base Model 3706A system switch/multimeter mainframe with three

options for added flexibility. This mainframe contains six slots for plug-in cards in a compact 2U high

(3.5 inches/89mm) enclosure that easily accommodates the needs of medium to high channel count

applications. When fully loaded, a mainframe can support up to 576 two-wire multiplexer channels

or 2,688 one-pole matrix crosspoints for unrivaled density and economical per channel costs.

High Performance, 7½-digit Multimeter (DMM)

The high performance multimeter option provides up to 7½-digit measurements, offering 26-bit

resolution to support your ever-increasing test accuracy requirements. This flexible resolution sup-

plies a DC reading rate from >14,000 readings/second at 3½ digits to 60 readings/second at 7½ digits

to accommodate a greater span of applications.

The multimeter does not use a card slot, so

you maintain all six slots in your mainframe.

In addition, the multimeter is wired to the

mainframe’s analog backplane, ensuring a high

quality signal path from each card channel to

the multimeter.

The multimeter supports 13 built-in measure-

ment functions, including: DCV, ACV, DCI,

ACI, frequency, period, two-wire ohms, four-wire ohms, three-wire RTD temperature, four-wire RTD

temperature, thermocouple temperature, thermistor temperature, and continuity. In addition, the

multimeter offers extended low ohms (1

) and low current (10µA) ranges. In-rack calibration is

supported, which reduces both maintenance and calibration time.

TSP Distributed Control Increases Test

Speed and Lowers Test Cost

TSP technology enhances instrument control by allowing users the choice

of using standard PC control or of creating embedded test scripts that

are executed on microprocessors within the instrument. By using TSP

test scripts instead of a PC for instrument control, you avoid communica-

tion delays between the PC controller and instrument, which results in

improved test throughput. Test scripts can contain math and decision-

making rules that further reduce the interaction between a host PC

and the instrument.

This form of distributed control supports the autonomous operation of

individual instruments or groups of instruments and can possibly remove

the need for a high level PC controller, which lowers test and ownership

costs. This is the same proven TSP technology found in our innovative

Series 2600B System SourceMeter® SMU instruments.

TSP-Link Technology for Easy and Seamless

System Coordination and Expansion

If your channel density requirements grow or if you need to process more

signal types, use TSP-Link Technology to expand your system. The TSP-

Link master/slave connection offers easy system expansion between Series

3700A mainframes. You can also use TSP-Link Technology to connect to

other TSP-Link enabled instruments such as Series 2600B SourceMeter

SMU instruments. Everything connected with TSP-Link can be controlled

by the master unit, just as if they were all housed in the same chassis.

This high speed system expansion interface lets users avoid the complex

and time consuming task of expanding their remote interfaces to another

mainframe. There is no need to add external triggers and remote com-

munication cables to individual instruments, since all TSP-Link connected

devices can be controlled from a single master unit.

Test Script Builder Software Suite

Test Script Builder is a software tool that is provided with all Series 3700A

instruments to help users easily create, modify, debug, and store TSP test

scripts. It supplies a project/file manager window to store and organize test

scripts, a text-sensitive program editor to create and modify test TSP code,

and an immediate instrument control window to send Ethernet, GPIB, and

USB commands and to receive data from the instrument. The immediate

window also allows users to see the output of a given test script and sim-

plifies debugging.

LXI Core 2011 with LXI Clock Synchronization, LXI Timestamped Data,

Transportable Memory, USB 2.0 Device Port

All Model 3706A mainframes contain a USB device port for easy transfer

of readings, configurations, and test scripts to memory sticks. This port,

which is located on the front panel, provides you with easy access to and

portability of measurement results. Simply plug in a memory stick and,

with a few simple keystrokes, gain access to virtually unlimited memory

storage. Additional capabilities include: saving and recalling system con-

figurations and storage for TSP scripts.
