MEASure:ARRay:CURRent:HARMonic?
FETCh:ARRay:CURRent:HARMonic?
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 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.

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 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.
