The URL of the remote spectrum monitor is entered along with the center frequency of the FM signal. The bin width of the FM deviation measurement can also be adjusted as needed.
The AM/FM demodulation option also enables the user to remotely capture AM/FM signals and listen to the signals via their PC/laptop. The AM/FM signals can also be saved as WAV files to be played at a later date.
Play AM or FM Demodulated Signals
These buttons demodulate the I/Q data and create an audio sound file. Playing a demodulated signal is useful if the demodulated signal is known. By listening to a demodulated signal, you can pin point the location of the interferer signal.
