As far as I know, there are no graphs for BER vs Q, Q vs Attenuation, BER vs Attenuation in the sample “Receiver Sensitivity BER – Q factor.osd”. However, if you use our new “BER test set”, you could get graphs for BER vs Attenuation. By the way, this sample is quite old. We usually measure BER vs OSNR, not attenuation. We have a new “set OSNR” component for the next release!
