MEASure:CURRent:NEUTral:HARMonic?
FETCh:CURRent:NEUTral:HARMonic?
These queries return the rms amplitude of the Nth harmonic of current in the neutral output
terminal of a three-phase AC source. The parameter is the desired harmonic number. Queries
sent with a value of 0 return the dc component. A value of 1 returns the fundamental output
frequency. 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.
