Harmonic distortion meter
Most measurements of electrical quantities, such as voltage, current, resistance, or frequency, can be carried out on a multirneter or an oscillcope. Unfortunately, measuring (harmonic) distortion in a.f. amplifiers requires rather more sophisticated, and thus more expensive, equipment. However, the adaptor presented here makes it possible for the harmonic distortion be viewed and analysed on an oscilloscope.
