4.20 Source Subsystem - Phase
This subsystem programs the output phases of the AC source. When phase commands are used
to program single-phase units, the only discernible effect in using the phase commands is to
cause an instantaneous shift in the output waveform phase.
Subsystem Syntax
[SOURce:]
PHASe
[:IMMediate] Sets the output phase
:MODE Sets the phase mode (FIX|STEP|PULS|LIST)
:TRIGgered Sets the triggered phase (step or pulse mode only)
PHASe
Phase Selectable
This commands sets the phase of the output voltage waveform relative to an internal reference.
The phase angle is programmed in degrees. Positive phase angles are used to program the
leading phase, and negative phase angles are used to program the lagging phase.
The PHASe command is not influenced by INSTrument:COUPle ALL. It applies only to the current
output phase selected by INSTrument:NSELect.
Command Syntax [SOURce:]PHASe[IMMediate]
Parameters -360º through +360º
*RST Value phase ø1 = 0°, phase ø2 = 240°, phase ø3 = 120°
Examples PHAS 45 PHASE MAX

PHASe:MODE
Phase Selectable
This command determines how the output phase is controlled during a triggered output transient.
The choices are:
FIXed The output phase is unaffected by a triggered output transient.
STEP The output phase is programmed to the value set by PHASe:TRIGgered
when a triggered transient occurs.
PULSe The output phase is changed to the value set by PHASe:TRIGgered for a
duration determined by the pulse commands.
LIST The waveform shape is controlled by the phase list when a triggered
transient occurs.
