Phase Selectable
These queries return an array of harmonic phases of output current in degrees, referenced
to the positive zero crossing of the fundamental component. The fundamental component
will return a value relative to the fundamental voltage.
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: 16 kHz in single-phase mode and 6.510 kHz in three-phase mode.
MX/RS Series II: 16 kHz in either 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.
