5.24. To Generate the Modulated Waveform
Modulation function is only used for CH1. Press the Mod button, then press F1 to
select Mod to generate modulated waveform. The waveform generator can modulate
waveform using AM, FM, PM, FSK and PWM. To turn off the modulation, press the Mod
button.
5.25. AM (Amplitude Modulation)
The modulated waveform consists of two parts: the Carrier Waveform and the Modulating
Waveform. The Carrier Waveform can only be Sine. In AM, the amplitude of the Carrier
Waveform varies with the instantaneous voltage of the modulating waveform. The user
interface of the AM is shown as below.
