The Tune & Listen feature can be used to identify an interfering AM or FM
signal. Also, AM/FM Metrics displays the demodulated signal and the audio
frequency spectrum.
The demodulated AM or FM signal can be heard through the internal speaker
or through headphones using the 3.5 mm jack located on the FieldFox side
panel.
The Analog Demod spectrum is displayed alongside the SA displayed trace.
