Dear Aseel,
you should be able to get all related metric information from BERT analyzer. Please check the graphs/results in the project browser or right click on the BERT component and choose Component view or Component results to view the different available results and graphs. The component will graph the BER versus the length of the fiber (parameter that you sweep). This feature works with single swept parameter not more.
please email me your project as a zip file to ahmad.atieh@optiwave.com if you need more information.
Regards,
Ahmad
