Harmonics Bar View: This function displays the frequency spectrum of the output
voltage or current waveform derived through FFT (fast Fourier
transform) analysis. The frequency spectrum is displayed in
graphical format, ranging from DC through the 49
th
harmonic, with
up to 25 harmonic components shown per screen; refer to Figure
5-237. Individual harmonics could be selected (shown with a
triangle along the horizontal axis) to display their parameter data
using the Right and Left arrow buttons, touch-screen, or encoder.
The upper right side presents the data for the selected harmonic:
harmonic number, frequency, percentage of fundamental, and
phase angle). Refer to Section 6.2.2 for additional information on
the harmonics graphical view.
