Hello Khadija Omran…
BER has been throughly in one of the prevoius posts in the forum…here is the link attached…

BER analyzer

For more information on BER analysis kindly refer

Hello Khadija Omran,
Actually, we calculate Minimum BER in optisystem using BER Analyzer which is found in electrical part of visualizer component library.
It is easy to find to Min. BER and Q-factor.
Here i upload an osd file
When you will double click on BER analyser, you will get value of Min. BER, Q-factor. You can get structure of eye diagram by just get tick on Show eye diagram tab in BER analyser window.

thank 🙂
I applied all of this but did not show BER
my system in this link
https://drive.google.com/open?id=0B9H50S0Lc2YPYm1EQ0lJV2Jiajg

Is it a way to link the BER Analyzer correct?
why did not show !!

Hello Khadija Omran,
I think i am right and i have attached the BER analyzer in right sense and i have got the results in BER analyzer.
I am uploading the jpeg image of screenshot of the results.

Thank you
Did not show any result .. Only Eye diagram but the min BER and Q factor zero

Hello khadija,
As rightly suggested by everyone how to visualize the results like in bit error rate ( BER ) and quality factor. Now the problem being that you are not able to get anything on the visualizer for BER and quality factor , well i suggest you to kindly upload the .osd file of your system design so that someone could help you.

.osd file grater than 20 MB Maximum file size allowed

my system in above link

[Aabid BabaParticipant]

Hello khadija,
Thanks for sharing the link but unfortunately it is some drop box and it needs to go for registration which is not convenient. It would have been more convenient if you would have been able to upload the .osd file here only. But i see your file is 24 MB file and you can’t exceed the file size. I suggest you to copy your all blocks and design a new file which could be smaller in size.

Hello khadija omran

As far as i know .osd file can never be that big. And sorry i am having problems opening whatever you have uploaded.
