Abstract
Jitter is a very important parameter in wired digital communication. It is usually measured by SDH transmission analyzer. When the jitter of SDH transmission analyzer is calibrated, the Bessel function ratio method is used. However, the method is not suitable for large jitter amplitude output from SDH transmission analyzer such as 50UIpp above. This paper introduces the wide-band frequency modulation method to calibrate the jitter amplitude of SDH analyzer, and the uncertainty evaluation results are given at the end of this paper
