Ah ok, I was looking at the UWB receiver. In this case I would set the BER Analyzer to use the Measured algorithm, because the eye diagram won’t give you an accurate BER estimation. The reason being the binary sequence has been regenerated at the output, since you can’t really view the eye diagram of an OFDM signal.
If you look at the eye diagram you will notice that it is a “perfect” eye diagram with no deviation and no noise. In this case the BER estimation will not reflect reality.
Cheers
