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.
