Phase Noise Modeling Using AWR VSS Software

Phase noise is one way to quantify timing noise in a signal, which is typically used in analog signals.  Phase noise in the frequency domain appears as jitter in the time domain.  With digital signals, jitter is the primary metric used to understand signal integrity and stability.  When dealing with digital signals, it is best to use jitter to quantify signal quality. Jitter has additional sources beyond random fluctuations in phase due to the edge rate of digital signals.

This presentation explains how to use the Visual System Simulation time-domain engine to measure phase noise.
