Pulse Width Modulation (PWM) Commands

PWM Overview

The following is an overview of the steps required to generate a PWM modulated waveform.

Enable PWM

Modulation

Configure Carrier

Select Modulation

Source

Select Shape

Select Modulating

Frequency

Set Duty Cycle/Pulse

Width

1. Turn on PWM modulation using the SOURce[1]: PWM:STATe

ON command.

2. Use the APPLy command to select a pulse waveform.

Alternatively, the FUNC, FREQ, AMPl, and DCOffs commands

can be used to create a pulse waveform with a designated

frequency, amplitude and offset.

3. Select an internal or external modulation source using the

SOURce[1]:PWM:SOUR command.

4. Use the SOURce[1]: PWM:INT:FUNC command to select a

sine, square, upramp, dnramp or triangle modulating

waveshape. For internal sources only.

5. Set the modulating frequency using the

SOURce[1]:PWM:INT:FREQ command. For internal sources

only.

6. Use the SOURce[1]:PWM:DUTY command to set the duty cycle

or Pulse Width.
