Signal Quality
Visualize signal quality, timing, and noise margins
Eye Height: Vertical opening at center. Larger = better noise margin.
Eye Width: Horizontal opening. Larger = more timing margin for sampling.
Crossing Points: Should be at consistent level (zero for balanced). Spread indicates jitter.
Closure: ISI, noise, and jitter cause eye to "close". Fully closed = unusable signal.
Optimal Sample: Center of the eye where opening is maximum.
