Analyzer Functions - HP 8590 E-Series User Manual

Analyzer Functions

determines the percent of amplitude modulation of the largest displayed
signal and its two sidebands. The sidebands are assumed to be entirely from
ON OFF
amplitude modulation. If there are differences in the sideband amplitude, the
larger value is used. The measurement runs continuously, re-executing at the
end of each sweep.
All three signal must be displayed. The frequency spacing of the sideband
signals must be the same within the span accuracy of the measurement.
All of the signals must be greater than the PEAK EXCURSION above the
THRESHOLD. The amplitude scale may be either linear or logarithmic.

turns off the spectrum analyzer phase locking. The counter is turned off so
ON OFF frequency correction is no longer done at the start of each sweep. Turning the
phase locking off increases measurement speed, but it decreases frequency
accuracy. This is a service diagnostic function and is for service use.
