Command

:PHAS[12]

 

 

Long

[:SOURce]:PHASe[12][:ADJust]

Form

Set & Query

 

 

Parameter

Numeric

 

 

Parameter suffix

DEG or RAD. A parameter without a suffix is interpreted as RAD.

*RST value

0.0

 

 

Specified limits

0 to 360° constrained by delay and period limits.

Functional

Programming the pulse phase also executes [:SOURce]:PULSe:HOLD

coupling

PHASe so that the pulse phase is held constant when the signal frequency

 

is changed.

 

 

Description Use this command to set/read the relative phase-delay of the output signal. This is equivalent to setting an absolute or percentage pulse-delay with [:SOURce]:PULSe:DELay.

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

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

Example

:PULS:DEL1

500NS

Set OUTPUT 1 delay to 500ns

 

:PHAS2 180

DEG

Set OUTPUT 2 phase to 180°

 

:PULS:DEL1:HOLD TIM

Hold OUTPUT 1 delay constant with varying perio d

 

:PULS:DEL2:HOLD PRAT

Hold OUTPUT 2 phase constant with varying period

Command

:PULS:DCYC[12]

Long

[:SOURce]:PULSe:DCYCle[12]

Form

Set & Query

Parameter

Numeric

Parameter suffix

PCT

*RST value

10.0% (derived from Width and Period)
