When I want to do Complete Levels Calibration, the selection under Execute->Levels Calibration, below selection is greyed out and do not permit to select, what do I set wrong?
This is because you do not select Spectrum Analyzer in the config -> Instrument Config, make sure you select Spectrum Analyzer under impairments package menu.
The reason is when we do the full calibration of PLTS system, we will use Spectrum Analyzer to do all the signal level measurements.
