Agilent quality
We know you can’t afford instrument downtime due
to hardware failures and unscheduled maintenance.
That’s why our engineers designed reliability into the
34970A/34972A: A rugged enclosure, state-of-the-art
surface mount construction throughout, reduced parts
counts, and rigorous and thorough testing on all aspects
of the product.
Take the guesswork out of relay maintenance
The 34970A/34972A uses our proprietary relay mainte-
nance system to help you to predict relay end-of-life and
avoid costly production line downtime. It automatically
counts every individual switch closure and stores it in
nonvolatile memory on each module. You can query the
total number of cycles on any individual channel so you can
schedule maintenance and avoid erratic end-of-life failures.
