[:SOURce[<n>]]:FUNCtion:PULSe:DCYCle
Syntax [:SOURce[<n>]]:FUNCtion:PULSe:DCYCle {<percent>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:PULSe:DCYCle? [MINimum|MAXimum]
Description Set the pulse duty cycle of the specified channel.
Query the pulse duty cycle of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<percent> Discrete 0.001% to 99.999% 50%
Explanation  The pulse duty cycle is defined as the percentage that the pulse width
( [:SOURce[<n>]]:FUNCtion:PULSe:WIDTh ) takes up in the pulse period
( [:SOURce[<n>]]:FUNCtion:PULSe:PERiod ).
 The range of the pulse duty cycle is limited by the “minimum pulse width” and
“pulse period” (for the ranges of the “minimum pulse width” and “pulse period”,
please refer to the “Signal Characteristics” of the “Specifications” in DG1000Z
User’s Guide ). The actual range of the pulse duty cycle is

—— pulse period.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the pulse duty cycle in scientific notation with 7 effective digits, for
example, 4.500000E+01 (the pulse duty cycle is 45%).
Example :SOUR1:FUNC:PULS:DCYC 45 /*Set the pulse duty cycle of CH1 to 45%*/
:SOUR1:FUNC:PULS:DCYC? /*Query the pulse duty cycle of CH1 and the query
returns 4.500000E+01*/
