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]? Returns amplitude of the Nth harmonic of current
:PHASe? 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.
