Command :PULS:DCYC[1]
Long
[:SOURce]:PULSe:DCYCle[1]
Form Set & Query
Parameter Numeric
Value coupling
*RST value 10.0% (derived from width and period)
Specified limits 0.001% to 99.9%, depends on width, transition & period.
Description Use this command to program the duty cycle of the pulse signal. If you
want to set an absolute pulse width use
[:SOURce]:PULSe:WIDTh[1]
.
If you want the pulse duty cycle to remain constant when the pulse
period is varied (rather than the absolute pulse width use)
:SOURce]:PULSe:HOLD[1] DCYCle
Example To set and hold the duty cycle:
Command :PULS:DEL[1]
Long
[:SOURce]:PULSe:DELay[1]
Form Set & Query
Parameter Numeric
Parameter suffix

with engineering prefixes. You can change the default unit using
[:SOURce]:PULSe:DELay[1]:UNIT.
