Harmonics Setup
For both voltage and current harmonics, a number of different parameters can
be set. These setting are independent of the mode that is currently selected.
Sequence: All or odd harmonics only
Range: The maximum harmonic (up to 50)
Format: Display harmonics as absolute values or as a percentage of the
fundamental (1st) harmonic.
Distortion Setup
For both voltage and current harmonics, a number of different parameters can
be set. These setting are independent of the mode that is currently selected.
For following settings can be made for distortion.
Formula: Series or difference (default = series formula)
Sequence: Include all harmonics or only odd harmonics in the series
formula. (default = all harmonics)
Range: The maximum harmonic to be included in the series formula.
(default = 7)
DC (H0): Include or exclude DC in the series formula. (default =
exclude)
Reference: rms or 1st harmonic. (default = rms)
See section 6.4 for details of the actual equations used.
