The benefits of jitter decomposition：
1. Jitter performance plays a crucial role in the bit error rate of a high-
speed digital communication system. Through a limited sample, the
jitter measurement value can be used to estimate the TJ at any bit error
rate if the RJ estimation is correct.
2. Jitter decomposition is a key tool to accurately derive each type of jitter
as well as total jitter in a system and identify the root causes of jitter
quickly.
Touch Jitter Decomposition to enter the jitter decomposition configuration menu.
A. Set the pattern mode between Auto and
Manual. In the Manual mode, the pattern length
in bits, which represents the repetition period of
the data sequence, can be set as user input. In
the Auto mode, the pattern length is
automatically detected
B. Pattern length. When Pattern Mode = Auto, this
area is read-only. The pattern length is a
necessary parameter to calculate DCD and
DDJ
C.
Enable/Disable the Bathtub plot. The "bottom"
of the bathtub expresses the degree of eye
opening under the target bit error rate.
The result of jitter decomposition will be shown in the measure area. Users can
