Do you hear the relays working when you change the
signal level?
If yes, and that's probably the case, i definitely
suspect burned-out attenuator resistors/modules
(HIGHLY probably due to excessive reverse power
(Signal generator directly plugged to a transceiver
which has been accidently keyed)).
Hi,
I have a 3325A and the amplitude attenuators are not working. I
opened it up and it has sealed black relays, not the unsealed ones
mentioned in the maintenance manual. When I run the front panel self-
test everything passes. Any suggestions on what to do next?
Thanks for your help,
P
