Phase Selectable
These queries return an array of harmonic phases of output voltage in degrees, referenced
to the positive zero crossing of the fundamental component. The fundamental component
will return a value relative to the fundamental voltage for phase A. Phase A will return a zero
value.
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:
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 the above frequencies are returned
as 0.
