Source Subsystem (Phase)
This subsystem programs the output phases of the . 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] <n> Sets the output phase
:MODE <mode> Sets the phase mode (FIX | STEP | PULS | LIST)
:TRIGgered <n> Sets the triggered phase (step or pulse mode only)
PHASe
Phase Selectable
This command 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.
