Having repaired the PSU section of my 2710, I'm now trying to deal with the other issues it has. I'm seeing the error message 'Cannot count VCO, IF'; I've checked the counter signals going into the microprocessor board and have measured the following:
J180 - 100MHz at -14dBm, bursts of approx 1us long, repeating every 12us.
J190 - 10 MHz at 0dBm
J195 - 100MHz at -8dBm changing to -4dBm regularly
Can anyone confirm whether or not these signals are what would be expected at the input to the counter, in particular the signal at P180?
