白皮书
The biggest problem in the analysis of jitter by separating a signal’s timing noise into its sub-components is the variation of measurements performed by different jitter test-sets on a given signal. Since the variation can span several hundred percent, it is important to understand which measurement is correct and why some measurements fail. To understand the strengths of different test techniques, learn how to compare very different techniques, and to learn how to specify a jitter analyzer’s accuracy and sensitivity, we built a transmitter capable of injecting arbitrary combinations of accurately calibrated levels of different types of jitter. We required that the applied jitter signals be consistent with the standard industry-wide conventions that all jitter analysis test equipment assume; for example, the random jitter signal was required to faithfully follow a Gaussian distribution over at least fourteen standard deviations.
