Using the high-end serial data analyser, such as Lecory SDA6000, the
analyser can analyze the data jitter, and give a report about which freq.
contribute most to jitter.

if you only want to estimate the jitter, you can only check the eye-diagram.

Subject: [SI-LIST] How to analyze jitter of data


> Dear all:
> Recently, I meet one problem about optic fiber. Two PCB could not
correctly communicate. The measured result showed that the jtter of the
optical signal is too large. Now I am measuring the spectrum electrical
input of the optic module.

> If the signal is clock-like, I could analyze the jitter by checking the
sideband. Currently, the signal is of data. How to analyze the spectrum in
order to find out what is the reason for jitter?
