TOTAL HARMONIC DISTORTION (THD) is the ratio, expressed in dBc, of the rms total of the first six harmonic

levels at the output to the level of the fundamental at the output. THD is calculated as:

(2)

6 harmonic frequencies.

SECOND HARMONIC DISTORTION (2ND HARM) is the difference expressed in dB, between the RMS power in

the input frequency at the output and the power in its 2nd harmonic level at the output.

THIRD HARMONIC DISTORTION (3RD HARM) is the difference, expressed in dB, between the RMS power in

the input frequency at the output and the power in its 3rd harmonic level at the output.
