[:SOURce[<n>]][:MOD]:PWM:STATe
Syntax [:SOURce[<n>]][:MOD]:PWM:STATe {ON|1|OFF|0}
[:SOURce[<n>]][:MOD]:PWM:STATe?
Description Turn on or off the PWM modulation function of the specified channel.
Query the on/off status of the PWM modulation function of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
{ON|1|OFF|0} Bool ON|1|OFF|0 OFF
Explanation  PWM (Pulse Width Modulation): the carrier pulse width changes with the
transient voltage of the modulating waveform.
 The PWM carrier waveform can only be pulse and the PWM function can only be
turned on when the current waveform of the specified channel is pulse. The
different settings of various parameters (such as the frequency, amplitude, DC
offset, pulse width and duty cycle) of the carrier waveform will influence the
PWM modulated waveform.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
 If the sweep function ( [:SOURce[<n>]]:SWEep:STATe ) or burst function
( [:SOURce[<n>]]:BURSt[:STATe] ) is currently enabled, it will be disabled
automatically when the modulation function is turned on.
Return Format The query returns ON or OFF.
Example Assume that the current waveform of CH1 is pulse,
:SOUR1:PWM:STAT ON /*Turn on the PWM modulation function of CH1*/
:SOUR1:PWM:STAT? /*Query the on/off status of the PWM modulation function
of CH1 and the query returns ON*/
