Abstract
A measurement setup is developed for accurate phase calibration of phasor measurement units (PMUs) and PMU calibrators. The measurement method is based on generating a reference signal with known phase with respect to a 1 pulse-per-second time reference using a stepped sine wave signal.

Measurement of Absolute Phase Error of Digitizers

TL;DR: In this article, the authors proposed a method for the measurement of digitizer absolute phase errors based on the characterization of generator phase response and measurement of the time delay between the sampling clock and a phase reference signal, taking into account the phase deviation introduced by generation system and the clock delay.
