Channel Scanner Mode (Option)

The Channel Scanner Mode provides the measurement of the signal power of multiple channels. The signal power is displayed as a bar graph or as a table, and the signal power of up to 20 channels can be measured. There are three measurement modes depending on how the channels are set up: channel scanner, frequency scanner and list scanner, all of which allow the bandwidth and number of channels to be set.

AM/FM/PM Analyzer Mode (Option)

RF spectrum: similar to the spectrum analyzer mode, the spectrum plot of the modulated Signal is displayed and the occupied bandwidth can be measured.

Audio Spectrum: displays the spectrum of the demodulated audio signal.

Audio Waveform: displays the waveform of the demodulated audio signal in the time domain.

Parameter analysis function: Carrier power, Demodulation rate, carrier frequency offset, modulation depth (AM), modulation frequency offset (FM), SINAD, modulation distortion, total harmonic distortion and other parameters of the modulated signal can be measured and analyzed.
