RIGOL: Eye Diagram Analysis for Signal Integrity Evaluation

Posted on: January 1st, 2026 by Kane Brady

The eye diagram remains one of the most powerful visual tools for evaluating digital signal quality.

By overlaying thousands of signal transitions, an eye diagram provides a clear view of noise, jitter, inter-symbol interference, and overall signal integrity. This application note explains how eye diagrams are generated, how to interpret key measurements such as eye height and eye width, and how eye mask testing can be used to verify compliance with industry requirements.

The guide also covers practical configuration steps and measurement techniques for NRZ, PAM3, and PAM4 signals, making it a valuable resource for engineers working with high-speed communication systems.
