DCD + ISI Histogram View
This view shows the DCD+ISI Histogram. It allows you to distinguish rising and falling edges and see the
effects of Data Dependent Jitter.
DCD + ISI vs. Span View
This view shows the DCD+ISI vs. Span of Unit Intervals. This allows you to see how the DCD+ISI
changes over a range of unit intervals. Zooming in on a vertical line reveals 3 lines. This represents the
histogram of that edge the center line is the Mean, the left and right show the Peak to Peak. The "raw"
line shows measured DCD+ISI. The "HPF" shows the result of applying the HPF filter.
1-Sigma vs. Span View
The 1-sigma vs. span view shows how the 1-sigma values change over an accumulation of unit intervals.
This view allows the user to see jitter modulation. It shows the 1-sigma values for many histograms.
This plot shows jitter components that are NOT correlated to the data and relates to Random and
Periodic jitter
