How to make Analog Demodulation (Metrics) Settings
The following softkeys are available when one of the Analog Demodulation
metrics measurements is pressed. See also, “How to select Tune & Listen” on
page 164.
If AM DSB, choose from:
— AM Top Y
– Determines the Y axis percentage (0% to ±100%) of the AM
demodulation waveform is displayed (Default = 100%).
If AM SSB, choose from:
— SSB Top Y
– Determines the Y axis voltage (0 nV to ±100mV) of the AM
SSB demodulation waveform is displayed (Default = 100 mV).
If FM, choose from:
— FM Top Y
– Determines the Y axis frequency (1 kHz to 1 GHz) of the FM
demodulation waveform is displayed (Default = 100 kHz).
If FM Stereo / RDS, choose from:
— FM Top Y
– Determines the Y axis frequency (1 kHz to 1 GHz) of the FM
demodulation waveform is displayed (Default = 100 kHz).
If PM, choose from:
— PM Top Y
– Determines the Y axis phase (0 to 100 radians) of the PM
demodulation waveform is displayed (Default = 5).
For either AM DSB, AM SSB, FM, FM Stereo / RDS, or PM, choose from:
Refer to Figure 9-5 on page 175, Figure 9-6 on page 176, and Figure 9-7 on
page 176, and Figure 9-8 on page 177.
— 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.
Choose from AM
, AM SSB, FM, FM Stereo / RDS, and PM.
—Then, press More
– opens a menu of softkeys: Average Type, Average
Count, and Demod View Time Freq.
