Pulse Width Modulation (PWM)
This section discusses PWM, which stands for pulse-width modulation. PWM is only available for the Pulse
waveform, and the pulse width varies according to the modulating signal. The amount by which the pulse width
varies is called the width deviation, and it can be specified as a percentage of the waveform period (that is, duty
cycle) or in units of time. For example, if you specify a pulse with 20% duty cycle and then enable PWM with a 5%
deviation, the duty cycle varies from 15% to 25% under control of the modulating signal.
To Select PWM
You cannot enable PWM when sweep or burst is enabled.
To avoid multiple waveform changes, enable modulation after configuring the other modulation parameters.
Front Panel Operations
1. Press [Waveform] > Pulse.
2. Press [Modulate] > Type AM > Type PWM.
3. Press Modulate ON | OFF > Modulate ON | OFF.
The waveform is output using the present carrier and modulating waveform settings.
SCPI Command
[SOURce[1|2]:]PWM:STATe {ON|1|OFF|0}
Modulating Waveform Shape
The modulating waveform shape (internal source) may be:
