buffer is determined by SENSe:SWEep:OFFSet:POINts.

Parameters None

MEASure:ARRay:CURRent:NEUTral:HARMonic?
FETCh:ARRay:CURRent:NEUTral:HARMonic?
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 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:HARMonic:PHASe?
FETCh:ARRay:CURRent:NEUTral:HARMonic:PHASe?
These queries return an array of harmonic phases of output current of the neutral output terminal
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.

This command selects the waveform array data format to be used. The default mode is binary
(BIN) which uses an IEEE floating point data format in which each data sample is transferred as a
4 byte floating point binary data word. Alternatively, an ASCII format may be selected (ASCii) in
which each data sample is sent as 8 ASCII Hex values representing the 4 byte IEEE floating point
data. Note that the transfer mode only applies to MEAS:ARR:VOLT and MEAS:ARR:CURR
queries. All other measurement queries always return ASCII data. Note that at power on, the
default mode is always set to binary (BIN).
