Oset Calibration
The unavoidable frequency-dependent deviations of the linearity of the di-
rectional coupler used for internal power measurement can be minimized
for each bandpass range.
The adjustment should be carried out at an output power of 1 kW.
Use your preferred reference wattmeter for the adjustment.
Selection of the bandpass range is done automatically during transmission.
The detected band is highlighted.
