MEASure:ARRay:CURRent:NEUTral?
FETCh:ARRay:CURRent:NEUTral?
Agilent 6834B Only
These queries return an array containing the instantaneous output current of the neutral output terminal in
amperes.
The output voltage and current are digitized whenever a measure command is given or whenever an
acquire trigger occurs. If digitization is caused by a measure command, the time interval between samples
is determined by the output frequency. For frequencies greater than 45Hz, the time interval is 25
microseconds. If digitization is caused by an acquire trigger, the time interval is set by
SENSe:SWEep:TINTerval, and the position of the trigger relative to the beginning of the data buffer is
determined by SENSe:SWEep:OFFSet:POINts.

MEASure:ARRay:CURRent:NEUTral:HARMonic?
FETCh:ARRay:CURRent:NEUTral:HARMonic?
Agilent 6834B Only
These queries return an array of harmonic amplitudes of output current of the neutral output terminal in
rms amperes.
The first value returned is the dc component, the second value is the fundamental frequency, and so on
up to the 50th harmonic. Harmonic orders can be measured up to the fundamental measurement
bandwidth of the measurement system, which is 12.6kHz. Thus, the maximum harmonic that can be
measured is dependent on the output frequency. Any harmonics that represent frequencies greater than
12.6kHz are returned as 0.
