To execute jitter injection, click on Jitter button and check Enable.
When Jitter Injection is turned ON, check mark appears on the Jitter button. The Stimulus Type (under Eye/Mask tab) is automatically changed to "Statistical".
See also Bit Pattern Type.
There are two types of jitter injection available to choose from:
Random Jitter - follows the Gaussian distribution and is represented by the rms value of the Random Jitter distribution.
Periodic Jitter - represented by peak-to-peak value.
In general, Deterministic Jitter and Random Jitter totals up to Total Jitter (TJ). Deterministic Jitter is bounded by a finite magnitude. It can be broken into jitter which is correlated to the data sequence and jitter that occurs independent of data. Periodic Jitter is data independent.
Jitter Unit: You can select from Unit Interval (UI) or Second. Second = Unit Interval / Data Rate
Display Limit: This is a probability density limit. Normally, it is not necessary to change this from default setting. This function allows you to execute a fine tuning of skirt of eye diagram. This applied to eye mask result. So that, you can have the same result on the mask test by adjusting this value. This is not applied to the eye result.
