Pulse-delay, PHAS2 180DEG | Agilent Technologies 660MHz guide

Programming Reference

SCPI Instrument Command List

Description Use this command to set/read the pulse-delay. Delay is the time between the start of the pulse period and the start of the leading-edge of the pulse.

If you want the pulse-delay to remain constant when the pulse period is

varied (rather than the phase-delay) use

[:SOURce]:PULSe:DELay[12]:HOLD TIME.

Example	:PULS:DEL1 500NS	Set OUTPUT1 delay to 500 ns
	:PHAS2 180 DEG	Set OUTPUT 2 phase to 180°
	:PULS:DEL1:HOLD TIME	Hold OUTPUT 1 delay constant with
		varying period
	:PULS:DEL2:HOLD PRAT	Hold OUTPUT 2 phase constant with
		varying period

Command	:PULS:DEL[12]:HOLD
Long	[:SOURce]:PULSe:DELay[12]:HOLD
Form	Set & Query
Parameter	TIME PRATio
*RST value	TIME
Description	Use this command to set/read the coupling between the pulse period and
	the pulse-delay:
	TIME	The absolute pulse-delay is held fixed when the pulse period is
		varied (Pulse phase varies).
	PRATio	The pulse phase-delay (delay as ratio of period) is held fixed
		when the pulse period is varied. (Pulse-delay varies).
Example	:PULS:DEL1 500ns	Set OUTPUT 1 delay to 500ns
	:PHAS2 180DEG	Set OUTPUT 2 phase to 180°
	:PULS:DEL1:HOLD TIME	Hold OUTPUT 1 delay constant with varying period
	:PULS:DEL2:HOLD PRAT	Hold OUTPUT 2 phase constant with varying period
