4.12 Voltage Measurement Subsystem

This subsystem programs the voltage 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]

:VOLTage

[:DC]?

Returns the dc component of the voltage

:AC?

Returns ac rms voltage

:ACDC?

Returns ac+dc rms voltage

:HARMonic

[:AMPLitude]?

Returns amplitude of the Nth harmonic of voltage

:PHASe?

Returns phase of the Nth harmonic of voltage

:THD?

Returns % of total harmonic distortion of voltage

:THD:MODE RMS | FUND

Sets THD calculation to either RMS or Fundamental
mode.

MEASure:VOLTage?
FETCh:VOLTage?

Phase Selectable

These queries return the dc component of the output voltage being sourced at the output
terminals.
