4.11 Power Measurement Subsystem
This subsystem programs the power measurement capability of the Lx\Ls Series. 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
MEASure:POWer?
FETCh:POWer?
Phase Selectable
These queries return the dc component of the power being sourced at the output terminals in
watts.
