Is there a standard setup for measuring the return loss(source impedance) of an RF source while it's transmitting?
Someone recommended A VNA sweep at frequencies close to the TX frequency, but I am not convinced because I have seen different results for freq.s lower/higher than the Tx.
And personally I don't think that the return loss of the side bands are necessarily always the same as the Tx frequency!
Any recommendations?
