[:SOURce[<n>]][:MOD]:PWM[:DEViation][:WIDTh]
Syntax
[:SOURce[<n>]][:MOD]:PWM[:DEViation][:WIDTh] {<deviation>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PWM[:DEViation][:WIDTh]? [MINimum|MAXimum]
Description
Sets the PWM width deviation of the specified channel.
Queries the PWM width deviation of the specified channel.

200 μs
Remarks
Width deviation represents the variation of the modulated waveform pulse width from the original
pulse width.
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
The width deviation is limited by the minimum pulse width and current edge time setting. The width
deviation cannot exceed the current pulse width.
If "Duty" is currently selected in the pulse of the specified channel, "Duty Dev" is displayed in the
interface when the PWM modulation function is enabled; if "Width" is currently selected in the pulse of
the specified channel, "Width Dev" is displayed in the interface when the PWM modulation function is
enabled.
Return Format
The query returns the PWM width deviation in scientific notation, with 7 effective digits. For example,
1.000000E-04 (the PWM width deviation is 100 us, (i.g. 0.0001 s)).
Example
:SOUR1:PWM 0.0001 /*Sets the PWM width deviation is 100 μs, (i.g. 0.0001 s).*/
:SOUR1:PWM? /*Queries the PWM width deviation of CH1 and the query returns
1.000000E-04.*/
[:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency
Syntax
[:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency? [MINimum|MAXimum]
Description
Sets the PWM modulation frequency of the specified channel.
Queries the PWM modulation frequency of the specified channel.

Remarks
This command is only applicable to the internal modulation source
[:SOURce[<n>]][:MOD]:PWM:SOURce
).
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
