4.3.6 Fixed TX gain principle
The SAILOR XTR Ka uses a TX IF gain concept. After calibration it provides a fixed average
gain from the TX-port of the BDU to the input of the BUC. Advantages of the fixed TX IF
gain principle are:
• Average TX IF gain independent of antenna cable length
1
• Compatibility with the TX Power control feature
When installing the SAILOR XTR Ka you make a cable calibration. At that point every
installation adjusts to the same average TX IF gain regardless of the ADU cable length.
Additionally the SAILOR XTR Ka system also compensates for variations of the cable
characteristics or loss over frequency.
Figure 4-27: Service - Line up
The ship must not move during the line-up procedure.
