The source is external. Use the [Aux In/Out]
connector at the rear panel.
Set the frequency at which the output phase shifts
between the carrier phase and 180° (internal
modulation only): 1 mHz to 20 kHz.
Set the modulating polarity
PWM (Pulse Width Modulation)
In PWM (Pulse Width Modulation), the pulse width of the pulse varies with the instantaneous
voltage of the modulating waveform. The carrier can only be a pulse waveform.
Press Waveforms → Pulse → Mod the parameters of PWM modulation are shown in Figure 35.

Note: The methods of setting the parameters of PSK are similar to AM.
