Customize your Keysight DAQ970A 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 DAQ970A 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 internal DMM, without the
need for external connections.
Use the chart below to help you pinpoint the modules that meet
your needs.
