PWM
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. In PWM, the width of the Carrier Waveform (Pulse) varies with
the instantaneous voltage of the modulating waveform. The parameters for PWM are
as shown in figure 2-46.
PWM can only be used for pulse modulation, press Mod, enter the modulation
interface, you may discover that the function key PWM is cryptic when you choose the
modulation type, but it will appear when you pressMod in the Pulse interface.
