FM Top Y
– Determines the Y axis frequency (1 kHz to 1 GHz) of the FM
demodulation waveform is displayed (Default = 100 kHz).
FM Top Y
– Determines the Y axis frequency (1 kHz to 1 GHz) of the FM
demodulation waveform is displayed (Default = 100 kHz).
PM Top Y
– Determines the Y axis phase (0 to 100 radians) of the PM
demodulation waveform is displayed (Default = 5).

Demod SwpT
– Sets the X-axis to display the demodulation sweep time for
the demodulated waveform (minimum = 50 μs; maximum = 50 ms).
Peak OFF ON
– This adds peak positive and peak negative metrics to the
main metrics measurement. For example, in FM peak ON will include peak
positive (Peak +) and negative (Peak -) frequency deviation metrics to
appear. Peak ON will also enable peak traces on the demodulation
waveform and audio frequency spectrum (Default = OFF).
Demod Type
– Sets the demodulation type.

Demod View Time
Average Type
– Selects the way the demodulated signal values are
averaged. Choices are Power (#PAvg annotation is displayed), Log (#LgAv
annotation is displayed), Voltage (#VAvg annotation is displayed). Auto is
the default and when selected the FieldFox chooses the type of averaging
that is used based on the current settings.
Average Count
– Determines the amount of averaging used (1 to 10K;
Default = 10).
Demod Filters
