Customize your Agilent 34970A/34972A with
plug-in modules
A complete selection of plug-in modules gives you high
quality measurement, switching, and control capabilities to
choose from. Modules include both low-frequency and RF
multiplexers, a matrix switch, a general-purpose switch, and
a multifunction module that includes digital input/output,
analog output, and totalizer capabilities. You can mix and
match modules to get just the functionality you need right
now—then change or add more channels later as your
application grows.
Modules for the 34970A/34972A are designed to make your
testing easier, faster, and more reliable. Here’s how:
Higher throughput
Our unique architecture incorporates a high-performance
microprocessor on each module, off loading the mainframe
processor and minimizing backplane communications for
faster throughput.

More channels in less space
Surface mount construction and a highly integrated design
minimize the space required for relay drive and interface
circuitry. High density on-module connectors save both
board and connector space normally required by a terminal
block. We use the latest technology to squeeze the most
out of the remaining board space, giving you up to
40 single-ended channels in roughly the same space
used by many data acquisition system terminal blocks.
Convenient connections
On-module screw-terminal connectors make wiring more
convenient. Built-in strain relief cable routing and cable tie
points keep your wiring secure and safe from accidental
tugs and pulls. An internal analog bus routes signals from
any of the low frequency multiplexers directly to the inter-
nal DMM, without the need for external connections.

meet your needs.
