start the data transfer. Valid offset values are from 0 thorugh 15. If both parameters are omitted,
all 16 blocks are transferred starting from offset 0 (first block).
Query Syntax MEASure:ARRay:CURRent[:DC]? [,]
FETCh:ARRay:CURRent[:DC]? [,]
Parameters Optional block and offset parameters ,. Where the first value
is the number of 256 sample blocks to transfer and the second value
is the first block (offset) to start with. Number of blocks is from 1 to 16,
offset is from 0 to 15.

Phase Selectable
These queries return an array of harmonic amplitudes of output current 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 16 kHz. Thus, the maximum harmonic that can
be measured is dependent on the output frequency. Any harmonics that represent frequencies
greater than 16 kHz are returned as 0.

MEASure:ARRay:CURRent:HARMonic:PHASe?
FETCh:ARRay:CURRent:HARMonic:PHASe?
Phase Selectable
These queries return an array of harmonic phases of output current in degrees, referenced to the
positive zero crossing of the fundamental component. The first value returned is the dc
component (always returned as 0 degrees phase), 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 16 kHz. Thus, the
maximum harmonic that can be measured is dependent on the output frequency. Any harmonics
that represent frequencies greater than 16 kHz are returned as 0.

MEASure:ARRay:CURRent:NEUTral?
FETCh:ARRay:CURRent:NEUTral?
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 acquisition trigger occurs. The acquisition sampling time interval is set by
