Abstract
A method and apparatus for generating a probability density function eye are provided. The method preferably includes the steps of acquiring an input waveform, performing a clock data recovery in accordance with the input waveform to determine one or more expected transition times and defining a plurality of unit intervals of the input waveform in accordance with the one or more expected transition times. One or more values of one or more data points may then be determined in accordance with the input waveform in accordance with the one or more expected transition times, and a category for each unit interval in accordance with its state and its position within the input waveform may also be determined. One or more histograms may then be generated for the determined one or more values for each category of unit intervals.
