Eye Diagram Analysis

Overlay multiple symbol periods to evaluate ISI and noise margin

Real-World Applications

Advanced oscilloscope measurement functions. In high-speed circuit design (DDR memory, PCIE, SATA interfaces, optical modules), engineers must observe eye diagrams to evaluate signal quality, jitter, and noise margins to determine if wiring is acceptable.

Experiment Steps

1. Eye Opening: Vertical opening reflects noise margin
2. Timing Margin: Horizontal opening reflects timing margin
3. ISI: Roll-off factor affects eye closure
