{|MINimum|MAXimum}
[:SOURce[]][:MOD]:PWM[:DEViation]:DCYCle? [MINimum|MAXimum]
Description Set the PWM duty cycle deviation of the specified channel.
Query the PWM duty cycle deviation of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real Refer to the “Explanation” 20%
Explanation  Duty cycle deviation represents the variation (in %) of the modulated waveform
duty cycle relative to the original pulse duty cycle .
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
 The duty cycle deviation is limited by the minimum duty cycle and current edge
time. The duty cycle deviation cannot exceed the current pulse duty cycle.
 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 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 /*Set the PWM duty cycle deviation of CH1 to 15%*/
:SOUR1:PWM:DCYC? /*Query the PWM duty cycle deviation of CH1 and the
query returns 1.500000E+01*/
