Generating Eye Diagrams In Vectorstar Vnas

The eye diagram of the optical module is very poor

The key parameters used to judge whether an eye diagram is normal include eye height, eye width, jitter, and extinction ratio. For beginners, this might sound confusing—but don't worry. You will also get practical selection criteria, common failure modes, and a head-to-head decision matrix for choosing test setups. The eye diagram test is an indispensable methodology for evaluating the signal integrity and performance of high-speed digital communication systems, particularly in the domain of optical transceivers. The diagram is generated by overlaying multiple traces of a signal on an oscilloscope.
