Built-in relay cycle counter
to facilitate test system maintenance
In a high-speed automatic test equipment (ATE)
system, unplanned downtime can be fatal to a high-
yield production line. To help test engineers perform
preventative maintenance by predicting relay end-of-
life, there are built-in relay cycle counters on the 5
high-density switching modules, thereby avoiding
costly production line downtime. The relay cycle
counter automatically counts every individual relay
closure and stores the number in the on-board non-
volatile memory. A simple "DIAG: CYC? Chan. xx "
command recalls the total number of cycles for
individual relays, making scheduled preventative
maintenance possible.
Compatibility with HP 3488A
The HP 3499 family is both hardware and software
compatible to the world's most popular switch/control
unit -the HP 3488A. All 13 of the HP 3488A modules
will work in the HP 3499A/B mainframes. The HP
3499A/B can be operated with SCPI (Standard
Commands for Programmable Instruments) or the HP
3488A command sets. Upgrading from an HP 3488A to
an HP 3499A doubles your channel capacity and lowers
your cost per channel with no additional cost in
modules.
Take the guesswork
out of relay maintenance
The HP 3499A/B use our proprietary
relay maintenance systems to help you
predict relay end-of-life and avoid costly
production line down time. It
automatically counts every individual
switch closure and stores it in non-
volatile memory on each module. You can
query the total number of cycles on any
individual channel so you can schedule
maintenance and avoid random end-of-
life failures.
