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:
MX Series I: 25.6 microseconds for single-phase mode and 76.8 microseconds for three-
phase mode.
MX/RS Series II: 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.
