Harmonic distortion (f)

The Harmonic distortion (f) measurement largely corresponds to a Harmonic distortion measurement being performed consecutively for several frequencies.

Accordingly the frequency values to be evaluated need to be selected in the Frequency steps setup.

Separate from the Harmonic distortion menu Harmonic distortion (f) holds its own settings for analysing frequency dependent distortions. The configuration needs to be done under Dist./Distortion Setup before measuring. Definition and handling are equivalent to the Distortion Info window. The parameters chosen under Select are displayed in separate curves corresponding to the channels.

The plot displays the distortion measurement of an overdriven Robo3 input showing the THD(f) in blue and underneath the harmonics K2 to K5 in relation to the excitation signal.
