Re-Sampling S-Parameters for Serial Data Link Analysis

摘要

A device and method of re-sampling a plurality of S-parameters for serial data link analysis is dislosed. The method includes storing a plurality of S-parameters sets, each S-parameter set being associated with a subsystem and having associated impulse responses and a time interval. An increased time interval is determine based on the time interval associated with each S-parameter set. The impulse responses are zero filled in each S-parameter set to maintain any wrapped ripples and increase the time interval. A plurality of resampled S-parameter sets are generated with a finger frequency resolution to cover the increased time interval.
