Fig. 4-19 Second Harmonic Amplitude
i) Calculate the harmonic distortion.
Change the distortion percentage of the second harmonic to fundamental wave as shown in Fig. 4-17. The unit can
be changed again to volt in order to read the voltage ratio of two signals.
j) Measure other harmonics.
Repeat Step (i) to (j) to other harmonics to be measured. Calculate the distortion percentage of each harmonic.
Total signal harmonic distortion percentage is also subject to frequent test. In order to test such parameter,
amplitude of each harmonic should be tested with linear unit (such as volt) rather than relative unit dBc. Press
[Amplitude], [Units] and [Volt] to set the amplitude unit as volt. The measured signal amplitude can be applied in the
following equation to calculate the total harmonic distortion:
