Measurement Subsystem (Current)
This subsystem programs the current 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]
:CURRent
[:DC]? Returns dc component of the current
:AC? Returns ac rms current
:ACDC? Returns ac+dc rms current
:AMPLitude
:MAX? Returns peak current
:CREStfactor? Returns current crestfactor
:HARMonic
[:AMPLitude]? <n> Returns amplitude of the Nth harmonic of current
:PHASe? <n> Returns phase of the Nth harmonic of current
:THD? Returns % of total harmonic distortion of current
:NEUTral
[:DC]? Returns neutral dc current (3-phase only)
:AC? Returns neutral ac rms current (3-phase only)
:ACDC? Returns neutral ac+dc rms current (3-phase only)
:HARMonic
[:AMPLitude]? <n> Returns neutral current harmonic amplitude (3-phase only)
:PHASe? <n> Returns neutral current harmonic phase (3-phase only)
