Set the HP E1440A frequency to 50 kHz and the amplitude to
9.99 mV(p-p).
OUTPUT Vxi;":FREQ SE4;:VOLT:AMPL 9.99MV1'
Set the spectrum analyzer controls to display the fundamental
and at least three harmonics. (It may be necessary to decrease
the video bandwidth to separate the harmonics from the noise
floor.) Verify that all harmonics are at least
60 dB below the
fundamental.
