The AUX MONITOR port on the HP 11848A Phase Noise Interface pro-
vides an output for monitoring the beatnote. Connecting an oscilloscope
to this output port allows the Phase Detector Constant to be estimated
from the peak amplitude of the beatnote. The peak voltage of the sine
wave equals the Phase Detector Constant in V/Rad.
