Series 3700A
System Switch/Multimeter
and Plug-In Cards
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 res-
olution to support your ever-increasing test accuracy requirements. This flexible resolution supplies
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.
Single Channel Reading Rates
The multimeter does not use a card slot, so
DCV/

you maintain all six slots in your mainframe.

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
W
) and low current (10µA) ranges. In-rack calibration is
supported, which reduces both maintenance and calibration time.

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.
System switch with high performance multimeter
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.

scripts in the

window.

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 config-
urations and storage for TSP scripts.

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 communi-
cation 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.

mainframe support point-and-click control for opening and closing switch-
es. A scan list builder is provided to guide users through the requirements
of a scan list (such as trigger and looping definitions) for more advanced
applications. When the mainframe is ordered with the multimeter, addi-
tional Web pages are included for measurement configuration and viewing,
including a graphing toolkit.
