Hi Alaa,
I am not sure I understand your question.
there are some examples showing how to use Electrical constellation visualizer and BER Analyzer, (one of them is attached).
Also, you can find other examples for the eye diagram viewer (one titled “Eye Diagram Analyzer.osd” from the examples in OptiSystem)
I encourage you to check the help of each component to determine the input signal types (bits, electrical, or optical) and how it works.
Hope that helps you.
if you have specific question please let us know to try to help
thanks
Mohamed
