SCPI Instrument Command List

Specified limits 0.1 99.9%, depends on Width & Period.

Value coupling

	Width =	Duty Cycle	⋅	Period
		100

Description Use this command to program the dutycycle of the pulse signal. If you want to set an absolute pulse-width use [:SOURce]:PULSe:WIDTh[12].

If you want the pulse dutycycle to remain constant when the pulse period is varied (rather than the absolute pulse width use)

[:SOURce]:PULSe:HOLD[12] DCYCle

Example	:PULS:DCYC1	25PCT	Set OUTPUT 1 dutycycle to 25%
	:PULS:HOLD1	DCYC	Hold dutycycle constant with varying period

Command	:PULS:DEL[12]
Long	[:SOURce]:PULSe:DELay[12]
Form	Set & Query
Parameter	Numeric
Parameter suffix	S with engineering prefixes. You can change the default unit using
	[:SOURce]:PULSe:DELay[12]:UNIT.
*RST value	0.0
Specified limits	0 to 3.00 µs

Value coupling
Phase =		Delay		⋅	360
