4.6 Current Measurement Subsystem

This subsystem programs the current measurement capability of the AC/DC 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

[:AC]? Returns ac rms current

:DC? Returns dc component of the current

:AMPLitude

:MAX? Returns peak current

:RESet Reset the peak current measurements

: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

MEASure:CURRent[:AC]?

FETCh:CURRent[:AC]?

Phase Selectable

These queries return the ac component rms current being sourced at the output terminals if

the voltage mode is set for AC only, and will return the AC plus the DC component if the

voltage mode is set for ACDC.

Query Syntax MEASure[:SCALar]:CURRent[:AC]?

FETCh[:SCALar]:CURRent[:AC]?

Parameters None

Examples MEAS:CURR:AC? FETC:CURR?

Returned Parameters <NR2>
