Customize Your 34970A With Plug-In Modules; Modules-At-A-Glance Selection Guide - Agilent Technologies 34970A Manual

Customize your Agilent 34970A 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 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 inte-
grated design minimize the space required for
relay drive and interface circuitry. High density
on-module connectors save both board and con-
nector 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 internal DMM, without the need for external
connections.

modules that meet your needs.
