I think the analyzer have a PLL unlock problem, cause from time

the receiver as well as the RF-generator dont work and you can
see a strange noise on the spectrum-scope.
This problem is solved. It was an cold solder point of an
transistor in the RF-Unit.
I'm looking for the calibration manual anyway.
