Pulse width modulation. The carrier is pulse.
The source is external. Use the [Aux In/Out]
connector at the rear panel.
Choose the modulating waveform.
Set the modulating waveform frequency.
Frequency range: 1 mHz to 20 kHz (Internal source
only).
To Set Pulse Width/Duty Deviation
Width Deviation represents the variation of the modulated waveform pulse width relative to
the original pulse width. Press Width Dev to highlight the parameter, and use the numeric
keyboard or knob to input the desired value as shown in the Figure 36.
