AM Modulation
The modulated waveform consists of two parts: the carrier and the modulating waveform. In
AM, the amplitude of the carrier varies proportionally with the instantaneous voltage of the
modulating waveform.
Press Mod → Type → AM, the parameters of AM modulation are shown in Figure 28.

Note: Noise and DC waveforms cannot be modulated.
