Rigol DSG5000-AMD - Analog Modulation Option for the DSG5000 Series
Amplitude Modulation (AM)
For amplitude modulation (AM), the amplitude of the RF carrier waveform varies with the the modulating signal linearly.
Frequency Modulation (FM)
For frequency modulation (FM), the frequency of the RF carrier waveform varies with the modulating signals.
Phase Modulation (PM)
Phase modulation (PM) indicates that the phase of the RF carrier waveform varies with the modulating signal.
