Data Acquisition & Switching
removed, so you can use the
34970A to collect data at a remote
location for later uploading to a
PC. The system configuration is also
held in non-volatile memory, so in
the event of a power failure the unit
automatically resumes scanning
when power is returned. And for
PC-based testing, Agilent BenchLink
Data Logger software is included
to simplify your test configurations,
data analysis and data management.
Automated Testing
For automated test and benchtop
automation applications, the
34970A’s three slots and choice of
eight plug-in switch and control
modules allow easy customization.
The 6

/

-digit internal DMM brings
you the power and performance
of a world-class standalone DMM,
but in a fraction of the space and
at a fraction of the cost. Software
drivers that support Agilent VEE
and National Instruments LabVIEW
TM
are available to make an easy inte-
gration of the 34970A into your test
system. Standard RS-232 and GPIB
interfaces and SCPI programming
language make integration even
easier. Our proprietary relay
maintenance system automatically
counts and stores every individual
switch closure to help you predict
relay end-of-life and avoid costly
production line downtime.
Module Overview
Up to three modules, in any combi-
nation, can be inserted into a single
mainframe. The 34970A’s internal
DMM connections are accessible
only through the 34901A, 34902A,
and 34908A multiplexers.
