DATA ACQUISITION SYSTEMS SELECTION
DATA ACQUISITION SYSTEMS
Keithley Data Acquisition Systems combine precision measurement, switching, and control into a single, tightly
integrated enclosure. They offer affordable alternatives to separate DMMs and switch systems, dataloggers/
recorders, plug-in card data acquisition equipment, and VXI/PXI systems.

CHOOSING YOUR DATA ACQUISITION SYSTEM
Designing the switching for an automated test system demands an understanding of the signals to be switched
and the tests to be performed. The following is a quick look at basic key decision points in the design of a
switching system.
1
Switch Coniguration
Multiplex switching can be used to connect one instrument
to multiple devices or multiple instruments to a single
device. Multiplex switching permits multiple simultaneous
connections and sequential or non-sequential switch
closures. A matrix switch coniguration is the most versatile
because it can connect multiple inputs to multiple outputs.
The isolated, or independent, switch coniguration consists
of individual relays, often with multiple poles, with no
connections between relays. For scanner (or multiplex)
cards, the channel is used as a switched input in measuring
circuits or as a switched output in sourcing circuits. For
switch cards, each channel’s signal paths are independent
of other channels.
2
Relay Types
Three key relay types are used. Electromechanical relays
offer the widest power range and a good life and speed at
a relatively low cost. Reed relays cost more but offer less
contact wear and bounce for a better life and speed than
electromechanical. Solid-state relays cost still more, but
offer the best life and speed with no contact wear or bounce.
3
Systemization
Connection types found on switch cards include both screw
terminals and mass-terminated connectors. At the instrument
level, TSP-Link master/slave connection offers easy system
expansion between Series 3700A mainframes and Series
2600B SourceMeter instruments.

modules in the 2750 mainframe
or up to two in the 2700 and 2701
mainframes.
2700 Series
The Series 2700 System Switch/Multimeter combines precision
measurement, switching, and control in a single, tightly integrated
enclosure for either rack-mount or bench-top applications used by data
loggers. The 2700 Series offers two- and ive-slot models, as well as an
Ethernet-based model for high speed and long distance communication.
Screw terminals use oversize
connectors for easier, mistake-free
wiring. Removable terminals available
for some models.
