Hi. Recently, i'm having trouble with the "phaselock lost" message, when i try to make a typical 2 port calibration. This seems to happen when the port 2 is involved, and seeing the s-parameters, if seems to happen about 45 ghz.
The message doesn't clear, so the problem it's there consistently. In the last months, we have been making un-calibrated measurements, with the frequency set to 45 ghz(using point sweep with external trigger), but we don´t save any parameter when shutting down the vna.
Any solution or diagnosis? I hope it wouldn't be some hardware problem .
Greetings
