Now we're ready to zoom in on a portion of the the distortion product spectrum. Go back to Page 1 of
the page control, and in the bandwidth control of the FFT analyzer select 500 Hz.In the "Center
Frequency" field select 1 kHz. We're narrowing the bandwidth by a factor of 64, still using 1k FFT lines,
and centering the new bandwidth on the notched out fundamental. Go back to Page 2, autoscale the
spectrum, which should now look like this:
