thank you alot

hi love kumar
i found it and try it and nothing different happens.

hello Ranjeet,
the problem is very clear and its :
the RF spectrum analyzer and electrical carrier analyzer did not give the same value for signal power as the pic show.

hello love kumar .,
thank you for your interested , but what is the pan option ? and where can i find and use it ?
Regards.

[ferasParticipant]

hello Fayiqz,
thank you for your interested
actually i used electrical power meter and its result was more closer to the electrical carrier analyzer results
but the question is how can we get the same results and why this happened
thank you again for your helping

[ferasParticipant]

any help please

dear damian , hello
can you please answer me on mu post https://optiwave.com/forums/topic/use-of-the-matlab-component-optical-system/#post-28929
i am really need a clear answer if you can

i installed it and it is run a 30-days trial optisystem 14 64-bit , and run well .

hi mohamed,
actually alistu is right in every word he typed hhhh
thank you all
Regards.

[ferasParticipant]

hello,
i am using optisystem 13 32-bit to design OFDM radio over fiber system that carried LTE signal over fiber optic channel and i am facing aproblem in getting a big BER value ( 0.33 ) and low Q factor but clear constellation diagram , even when run the simulation without any fiber channel (( only modulate and demodulate )) it still give me the same BER value without any change , i hope you to give me the reason why that happened and how can i get the right BER that depending to the channel .
thank you very much
