AM detector
Diode voltage
monitor output
Measure the monitor output voltage on the AM detector with an
oscilloscope or voltmeter. Locate the diode detector's DC voltage along the
bottom of the AM sensitivity graph
calibration line and over, the equivalent phase detector constant can then
be read from the left side of the graph. The measured data will be plotted as
single-sideband AM noise in dBc/Hz.
Measure noise data and interpret the results.
