Figure 6-78. Combined Effects of Amplitude and Phase Modulation
Using the demodulation capabilities of the analyzer, it is possible to view the amplitude or
the phase component of the modulation separately. The window menu includes the following

Forward transform range. In the forward transform (from CW time to the frequency domain),
range is dellned as the frequency span that can be displayed before aliasing occurs, and is
similar to range as defined for time domain measurements In the range formula, substitute
time span for frequency span.
