FFT View
This view shows an FFT of the Periodic jitter. It allows you to help diagnose and determine the
frequencies at which Periodic jitter may be a problem. Periodic jitter is often due to crosstalk from clock
or data lines, or power supply noise.
Bathtub Curve View
The Bathtub curve shows the predicted Total jitter at a specific Bit Error Rate. Bit Error Rate is displayed
on the vertical axis and one UI is displayed on the horizontal axis. As jitter increases, the two lines will
move closer to each other. Random jitter affects the slope of the lines. A small change in RJ has a
larger effect on TJ than the same change in deterministic jitter. Deterministic jitter adds a constant
offset and will often appear as a "shelf" on one or both of the lines
