10.47 Calibration – Tx Port 1
This page is used for calibrating the Coupler coupling loss settings and the Channel BTx Power levels.
Note: Only channels that have a frequency programmed, and which have been enabled will be displayed.
Tx Port Losses:
Forward Coupling:
The combined value of the Coupler forward coupling loss and the connecting cable insertion loss for this Tx Port. This value is
used to calculate the reported power level for channels on this Port.
Reverse Coupling:
The combined value of the Coupler forward coupling loss and the connecting cable insertion loss for this Tx Port. This value is
used to calculate the reflected power level for channels on this port and contributes to the reported VSWR figure.
Antenna Feeder:
The loss of the Antenna Feeder cable for this Port. This value is used to compensate the calculated Fwd and Rev Power levels
so that the reported VSWR figure represents the VSWR value as seen at the Antenna. The value entered in this field should
represent the insertion loss in one direction of the feeder only (i.e. from the Coupler “to” the antenna).
