Syntax

[:SOURce[]][:MOD]:PWM[:DEViation][:WIDTh]

{|MINimum|MAXimum}
[:SOURce[]][:MOD]:PWM[:DEViation][:WIDTh]? [MINimum|MAXimum]

Explanation

 Width deviation represents the variation of the modulated waveform pulse

width relative to the original pulse width.

 When [:SOURce[]] or [] 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. The width deviation cannot exceed the current pulse width.

 If the “Duty Cycle” is currently selected in the pulse of the specified channel

(

[:SOURce[]]:PULSe:HOLD

), “Duty Dev” is displayed in the interface

when the PWM modulation function is enabled; if the “Pulse 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 100us, namely

0.0001s).

Example

:SOUR1:PWM 0.0001 /*Set the PWM width deviation of CH1 to 100us (namely

0.0001s)*/

:SOUR1:PWM? /*Query the PWM width deviation of CH1 and the query

returns 1.000000E-04*/
