2016-10-22 direct/inverted spectrum:

The spectrum generated at transmitter after modulation depends on the LO frequency to generate carrier. It can be higher than the Uplink frequency or lower.   In one case the carrier frequency generates

2016-10-21 Two carrier operation:

Satellite operations for single carrier or multi carrier are not allowed by satellite owner to take it to saturation, both at input and output with IBO AND OBO specifications. The user earth station compulsorily

2016-10-17 Two carrier operation:

No. The power output is corresponding to power input. Gain does not change with input.

2016-09-23 Data Loss / bandwidth limitation:

You are correct. Try with roll of factor. And check your data rate measurement, the band width setting does not change data rates at receiver, but distortion at low C/N results in that type of results

2016-06-15 Backoff in Satellite Communication:

I am sure what you are calling 'back off' is not correct. It can be if we have negative margin from the link budget..etc. we should do link calculations and adjust the Power and antenna gains such that
