Hello,
Thanks for reaching out to us.
Your question is not clear to me but if you want to understand about the BER Analyzer graph plots and it’s operation, I suggest you to have a look at the BER Analyzer OptiSystem Help. You can read it by double clicking the BER Analyzer in the component library at: Default/Visualizer Library/Electrical/
Hope this helps?
Let me know if you have any further questions at support@optiwave.com.
Warm Regards,
Saurabh Bedi.
