Sine-Fit Estimation of Time-Base Distortion Based on Inner-Triggering

Abstract:

This paper describes a new sine-fit method for estimating the time-base distortion based on inner-triggering mechanism. In order to improve the efficiency of the iteration, the method uses sub-iterations to get the iterative initial value. Since the instrument based on inner-triggering mechanism was difficult to measure orthogonal signals, the method does not require two sets of mutually orthogonal sinusoidal calibration signal, but requires multiple sinusoidal calibration signals with different phases and frequencies. The experiments show that the method is used to estimate the time-base distortion based on sequential equivalent sampling.
