Total Harmonic Distortion (THD) - A percentage that is used to identify the
degree of the noise/unclean signal in a power source’s output waveform.
Transient - a momentary change (spike or dip) in a voltage or current waveform
that can affect the performance of the DUT.
Verification - comparison of measured results against a specification, usually the
manufacturer's published performance figures for the product (e.g. Error = -0.04V,
Spec = ±0.03V, result: "FAIL").
Voltage - The amount of force that is needed to move current from point to point.
Measured in volts.
