Hello,
there is a feature in OptiSystem where you can create images for eye diagrams or any other plots of the visualizers. You need to access the project browser, then select the desired image and right click on it to create the frames or video. you may define a parameter in the Matlab component and sweep that parameter.
please let me know if the issue is not resolved through email (ahmad.atieh@optiwave.com).
Regards,
Ahmad
