MEASure:CURRent:HARMonic:PHASe?
FETCh:CURRent:HARMonic:PHASe?
Phase Selectable
These queries return the phase angle of the Nth harmonic of output current, 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 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.
