Jitter/Noise Component
The Jitter/Noise panel allows you to input or import jitter and noise parameters. JNEye provides extensive
transmitter jitter and noise modeling and configuration capabilities.
The following figure shows the jitter decomposition diagram and the breakdown of jitter components.

In JNEye when Pre-emphasis is selected as Manual or Auto with Manual Starting Point
(2)
“0” = non-inverted which is positive tap selections in JNEye; “1” = inverted which is negative tap
selections in JNEye.
