Measurement Subsystem (Power)
This subsystem programs the power measurement capability of the ac source. Two measurement
commands are available: MEASure and FETCh. MEASure triggers the acquisition of new measurement
data before returning a reading. FETCh returns a reading computed from previously acquired data.
Individual outputs of a three-phase source are specified by the setting of INSTrument:NSELect.
Subsystem Syntax
MEASure | FETCh
[:SCALar]
:POWer
[:DC]? Returns the dc component of power
:AC
[:REAL]? Returns real power
:APParent? Returns VA
:REACtive? Returns VAR
:PFACtor? Returns power factor
:TOTal? Returns real 3-phase total power
