On my 8566B, I found that I have little or no output from the 100Mhz cal signal as well.? I haven't lifted the unit out of the rack yet, but to be clear, I have a blinking PL1 Unlock, PL2 Unlock and REF Unlock as well as the missing 100Mhz.? Actually, the 100Mhz seems to be there but won't drive a 50ohm load at all.
I'll check the voltages today.? By the way, I hope I need something specialized to fix this beast as I always enjoy a purchasing opportunity.? I have 2 x 8568Bs, lots of scopes and voltmeters, signal generators, etc.? What else could I need?
Any input?
Thanks
