Harmonic Measurements

Description
►
The Harmonic function can be used to easily measure the amplitude of the
fundamental frequency and its harmonic frequencies up to the 10
The function can also measure the amplitude relative to the fundamental
(dBc) and the total harmonic distortion (THD).
Measurement ítems
►

Amplitude: Amplitude of each harmonic (dBm).

dBc: Amplitude of each harmonic relative to the fundamental.

THD: The square root of the sum of the amplitude of each harmonic
frequency squared, divided by the amplitude of the fundamental
frequency.
