MEASure:VOLTage:HARMonic?
FETCh:VOLTage:HARMonic?
Phase Selectable
These queries return the rms amplitude of the Nth harmonic of output voltage. 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 queried up to the fundamental
measurement bandwidth of the measurement system:
10.4 microseconds for single-phase mode and 31.2 microseconds for three-phase mode.
Thus, the maximum harmonic that can be measured is dependent on the output frequency. Any
harmonics that represent frequencies greater than above frequencies are returned as 0.

MEASure:VOLTage:HARMonic:PHASe?
FETCh:VOLTage:HARMonic:PHASe?
Phase Selectable
These queries return the phase angle of the Nth harmonic of output voltage, referenced to the positive
zero crossing of the fundamental component.
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 queried
