UI Distrib view
Unit Interval distribution plot. This shows all measurement data taken of the serial data signal during the
DCD+ISI measurement segment of the acquire run. The Unit Interval number is directly measured by the
system and shows rising and falling edges. This plot does not relate directly to any number in the
Summary view, but does give an idea of the quality of data that was acquired. The edge location in the
pattern can be determined from this plot and compared to the DCD+ISI vs. Edge view. A zoomed in view
of this plot will show three lines at each edge position; these lines indicate the average location of each
edge and the pk-pk size of all measurements taken of each edge.
