    Posting my question again: maybe I did not explain my problem clearly? I was sure that out in this site's huge readership someone would be able to give me an answer to a possible reverse RF accident. Here goes...I accidentally transmitted an unmodulated UHF signal (30 watts) into the RF output jack of my HP8640B. This is a common, stupid, mistake and there is an option (OPT3) diode that will provide some protection against it. I do not have that option. My gen still works, the attenuator seems to be OK. How can I be sure that some damage has not been done to the output calibration? Does anyone out there have any experience with this sig gen and this problem?
