Demod
Sets the demodulation type to AM or FM; or disable the demodulation function. The
default is Off.
Remarks:
⚫ After AM (or FM) demodulation is enabled, the system will enable a marker
automatically. Place it at the center frequency and perform AM (or FM)
demodulation at this frequency point.
⚫ RSA3000 provides an earphone jack, and the demodulated signal can be output
in audio frequency (AF) mode through the earphone. The frequency and
intensity of AF denotes the frequency and amplitude of the signal respectively.
Demod Setup
1. Earphone
Sets the status of the earphone. When it is on, the demodulated signal can be
heard through the earphone during the demodulation. By default, it is Off.
2. Volume
