Abstract
A method and system for separating and determining the total jitter component of a signal under test includes a process for obtaining the time interval error (TIE) spectrum of the signal under test. The TIE spectrum contains multiple frequency bins. This method identifies the frequency bins in the TIE spectrum that contain deterministic jitter. This method includes a process for determining the total jitter component of the signal based on the frequency bins in the N-UI spectrum of the signal under test that correspond to the identified frequency bins in the TIE spectrum.
