Pre-characterization

The pre-characterization step is used to correct the frequency offset between the VSG and the vna's receivers.Therefore this step is only available if the RF source 1 is a VSG. It is not mandatory, it is only usefull for the LF measurement and some instrument are accurate enougth and don't need it.

The bench must be set as specified on the schematic. When performing the pre-characterization, a progress bar will appear.
