A recovered TX UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is
created using all edges of the 250 consecutive UI in the center of the 3500 UI used for calculating the
TX UI.
NOTE
It is recommended that the recovered TX UI is calculated using all edges in
the 3500 consecutive UI interval with a fit algorithm using a minimization
merit function (for example, least squares and median deviation fits).
