60 UTG1000A Series

The shape of PSK modulation waveform checked through oscilloscope is shown as following:

4.1.7 Pulse Width Modulation (PWM)

In pulse width modulation, modulated waveform is usually composed of carrier wave and modulation shape, and
the pulse width of carrier wave will change as modulation shape amplitude changes.
