When we use spectrum analyzer to measure antenna receive power for gain calculation, i find out that the spectrum analyzer can measure few kind of powers like channel power, average power and total power. So which kind of power should i choose? Ak-7}i

During the measurement with the spectrum analyzer, is it a must to see a peak in the receive power vs frequency plot? I found out that it still showing some power value even the screen does not show a peak. .. g4qdm{BL
