Hi Jaap,
I'm back on the 2712 diagnosis...
I tested all the relays in the RF Attenuator block...and they were good, but upon reassembly the issue still exists: it does indeed show input, but the level is some 24 dB down, frequency dependent. I had thought the Calibrator signal was proper, but the unit fails just about all the Amplitude Normalizations, so the problem likely exists with the calibration signal as well. Since the RF Attenuator relays are OK, the issue must be afterwards, in the 1st Converter, LO or some other block I do not have test equipment to check, I only have a 350 MHz scope...
Barring any further ideas from the group, is there anyone in the US Southeast who repairs these older Tek gear?
Thanks for the help,
Howard Hoyt
