Relay Cycle Counts
The Agilent 3499A/B/C can read and track the relay cycle counts on some
plug-in modules. This feature can be very useful in switching systems to
track relay failures and predict system maintenance requirements.
This feature is supported in 3488 Mode by the Agilent N2260A,
N2261A, N2262A, N2264A, N2265A, N2266A, N2267A, N2268A,
N2270A, and N2280A/81A modules.
The cycle counts of the tree relays (s98 & s99) on an N2260A or
N2266A can also be queried.
Front-Panel Operation: Press View, use the knob to select “RELAY
CYCLES”, and press Enter. Turn the knob to select the relay channel
of interest. The display shows the channel cycle count.
Remote Interface Operation: This feature is only available from the
front panel in 3488 mode.
