Question
If we have a negative back off in computing link budget for satellite communication. what does that mean?

Can the earth station transmit at a power level below saturation?


Thanks and Regards

Answer
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 we should arrive at positive margin. And based on the Satellite parameters, this margin will allow us to strict compliance of standards without loss of service.
