How is total harmonic distortion measured?
Harmonic distortion may be measured by applying a spectrally clean sine wave voltage signal to the input of the amplifier under test (may require a band pass or low pass filter if the excitation RF source has high harmonic output content).
What is THD in meter?
Total harmonic distortion, or THD, is one way to gauge power supply quality. It indicates how much of a harmonic component the voltage and current waveforms contain, and it serves as an indicator of the extent of the waveform distortion that is caused as a result.
Which instrument measures harmonic distortion?
Harmonic distortion meters are instruments that measure harmonic distortion or phase position. Harmonic distortion is a common problem in: power systems. electronic ballasts.
Can you measure THD with oscilloscope?
The oscilloscope allows the waveforms to be viewed in the time domain and the spectrum allows the harmonics to be displayed and THD to be automatically measured.
