SCPI Instrument Command List

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 absolu te 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 S with engineering prefixes. You can change the default unit using

[:SOURce]:PULSe:DELay[1]:UNIT.

Value coupling

*RST value 0.0

Width = Duty Cycle100 ×Period

:PULS:DCYC 25PCT

:PULS:HOLD DCYC

Set OUTPUT duty cycle to 25%

Hold duty cycle constant with varying period

Phase = Delay

Period ×360

Delay% = Delay

Period ×100
