Measurements for Eye Diagrams
Timing Jitter
The timing jitter of an eye diagram is a measurement of the variance in
time locations of the crossing point. Horizontal time histograms are
constructed, and the histogram having the smallest variance determines
the crossing point. The standard deviation of this histogram determines the
RMS timing jitter and the extreme points (largest and smallest time values)
in the histogram determine the peak-to-peak timing jitter.
Timing jitter is applied to the magnitude of the signal.
