Hi, I want to measure the gain and phase difference of a 1.5 GHz signal to a reference signal.


To have a better measure accuracy, should I choose the power level of the reference signal as -30 dBm or as close to the receiving signal as possible? the receiving signal is about -7 dBm.


Does it follow the same rules for both gain and phase measurement?


Look forward your reply. Thank you very much.
