Before starting measurements and calibration, set up the following VNA parameters:
•Set up default parameters.
•Select the traces and assign measured S-parameters to them.
•Set up the frequency range and the number of frequency points.
•Set up the output power level at no more than -5 dBm.
•Set up the IF bandwidth.
These parameters are set up in the VNA software. The setting procedure is described in detail in the VNA Operating Manual.
