Carrier Wave Waveform
PWM carrier wave waveform can only be pulse wave. After PWM modulation, press carrier parametersoftkey to
enter carrier wave waveform selection interface, then it can be seen that Pulse Wave label is selected
automatically.
Carrier Wave Frequency Setting
Settable range of pulse wave frequency is from 500uH to 25MHz, and the default frequency is 1kHz. Press
Parameter→ Frequency softkey to change frequency, then enter required numerical value, and select unit.
Carrier Wave Duty Cycle Setting
Settable range of pulse wave duty cycle is 0.01%~99.99%, and the default duty cycle is 50%. Press Parameter→
Frequencysoftkey to change, then enter required numerical value, and select unit.
Modulation Source Selection
The device can select internal modulation source or external modulation source. If need to change, press
