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 d elay) use
[:SOURce]:PULSe:DELay[1]:HOLD PRATio.
Example To set and hold the phase delay:
D
elay = Phase 360 Period
×
:PHAS 180 DEG
:PULS:DEL:HOLD PRAT
Set OUTPUT phase to 180°
Hold OUTPUT phase constant with varying
period
