Command :PHAS[1]

Long

[:SOURce]:PHASe[1][:ADJust]

Form Set & Query

Parameter Numeric

Parameter suffix

DEG

or

RAD

. A parameter without a suffix is interpreted as

RAD

.

Functional

coupling

Programming the pulse phase also executes

[:SOURce]:PULSe:HOLD

PHASe

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

is changed.

Value coupling

*RST value 0.0

Specified limits 0 to 360

°

constrained by delay and period limits.

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[1]:HOLD PRATio

.

Example To set and hold the phase delay:

:PHAS 180 DEG

:PULS:DEL:HOLD PRAT

Set OUTPUT phase to 180
