The spectrum analyzer chooses appropriate values for
these functions depending on the selected frequency
and span (or start and stop frequencies). These values
are set according to the coupled ratios stored under
VBW/RBW RATIO or RBW/SPAN RATIO. If no ratios
are stored, default ratios are used instead.
Front-panel key access:
AM DEMOD
Not available in normalized mode.
ON OFF
Turns AM demodulation ON or OFF. If no marker is
active and the frequency span is greater than 0 Hz,
pressing AM DEMOD ON OFF automatically places a
marker at the center of the trace and demodulates the
signal at that marker position. Activating AM
demodulation turns off FM demodulation, if it is on.
When the frequency span is greater than 0 Hz, a 10
kHz resolution bandwidth is used during
demodulation, regardless of the bandwidth annotated
on the screen. When the span is equal to 0 Hz, the
displayed bandwidth is used. In either case the video
bandwidth is not applied to the demodulation.
Front-panel key access:
Accesses a menu of demodulation functions, which are
AM/FM DEMOD
as follows: AM DEMOD ON OFF, FM DEMOD ON
OFF, MARKER NORMAL or MARKER DELTA, PEAK
SEARCH, and NEXT PEAK. When AM or FM
demodulation is activated, the demodulated signal is
output to the both the spectrum analyzer internal
speaker, and the earphone jack connector. The
earphone jack connector is located on the rear panel of
the spectrum analyzer.
Front-panel key access:
Accesses functions that allow you to specify a
AMPCOR MENU
correction to, or normalization of, the spectrum
analyzer measurement. The corrections are entered as
frequency-amplitude pairs and can be used to correct
for variations in the flatness of the measurement
system.
Front-panel key access:
Allows you to turn the amplitude correction function
AMPCOR ON OFF
on and off. Correction points can be used to specify a
correction to, or normalization of, the spectrum
analyzer measurement.
