17.Calculate the difference between the amplitude of marked signal
For example, if the fundamental amplitude for a fundamental
frequency of 10 MHz is +1.2 dBm and the marker amplitude is
40.8 dBm, the difference is 42 dBc.
Record this difference as the non-harmonic response amplitude for the
appropriate spectrum analyzer center frequency and microwave
spectrum analyzer start and stop frequency settings in
Non-Harmonic Amplitude
