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

Remarks
 Duty cycle deviation represents the variation of the modulated waveform duty cycle from the original
pulse duty cycle, expressed in %.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 Duty cycle deviation is limited by the minimum duty cycle and current edge time setting. The duty cycle
deviation cannot exceed the current pulse duty cycle.
 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 duty cycle deviation in scientific notation, with 7 effective digits. For example,
1.500000E+01 (the PWM duty cycle deviation is 15%).
Example
:SOUR1:PWM:DCYC 15 /*Sets the PWM duty cycle deviation of CH1 to 15%.*/
:SOUR1:PWM:DCYC? /*Queries the PWM duty cycle deviation of CH1 and the query returns
1.500000E+01.*/

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.

 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.
