Example
Operating the spectrum analyzer in zero span. The modulation waveform of an AM signal can be displayed in the
time domain.
In the frequency domain, we can accurately deter-

To demodulate the AM, increase the resolution band-
width to include both sidebands with the IF passband.
Position the signal at the reference level and select a
linear voltage display
