Tuner Calibration

Symptoms / Solutions:

Starting the tuner calibration using an R&S ZNB, the VNA correction is turned off and not used. The tuner continues to calibrate with the VNA in uncorrected.

This problem can be corrected by upgrading the R&S ZNB firmware to 2.80 or newer. Once updating the firmware, FDCS should correctly setup the VNA to calibrate with correction on.
