An estimate of the jitter of test generators using time-measuring apparatus

摘要

A method of estimating the jitter of test pulse generators using time-measuring apparatus (event timers) is considered. It is shown that the covariance of results of simultaneous measurements of the period by two measuring instruments gives an estimate of the jitter of the period of the test sequence. An experimental estimate of a jitter of 0.66 psec with an error of 8 fsec is obtained. The method enables generators of test pulse trains with small jitter to be checked and enables the results to be used further to test precision time measuring instruments.
