
The harmonic analysis function can be implemented on the 4 channels

Display of the measurements made:

RMS level of the signal

total harmonic distortion with respect to the RMS value of the fundamental (THD).

RMS level of the harmonic selected

ratio in % of the RMS value of the selected harmonic to the RMS value of the fundamental

frequency of the selected harmonic

phase of the selected harmonic/fundamental
