hello everyone , i need to plot Qfactor Vs Launched power the problem is when the BER goes to 0 at a specific launched power, how can i plot the Q factor curve at this point given that BER = 0 , the Q factor equal to infinity ?

Dear Oussama,
Usually the Q factor is platter versus an increasing range of launched power (LP). therefore, for smaller LP you should get higher BER and very low BER or equal to 0 when LP is high. If your units are in db and dbm, then you should be fine. One more thing smaller BER indicates larger Q value and better link performance. Hope this will help.
