Hello Friends, I have two HP 3456A's that have the same "-3" fault in the "test" mode. Both DVM's started exhibiting this same fault about the same time. I've troubleshot one of the DVM's to a failure in the Isolation Logic "Transmitter." I have no waveform at the output of A3T1. Before I continue with troubleshooting I thought I'd ask a question of the group. Is there a common mode failure of these DVM? Is there something in particular or area that I should be looking at/for? It's probably coincidental that they would both fail at about the same time with the same -3 fault. Your input is greatly appreciated. Best regards,
