Hi all,

I manage to make the BER value match the formula [BER= 0.5*erfc(Q/sqrt(2))] by changing algorithm parameter in the BER analyser from Measured to Gaussian, but when I change algorithm to Gaussian I noticed that the BER from BER analyser is much smaller than the BER test set and the Q factor is match the value with the BER in the BER analyser as it is in the attached file.
and if the algorithm is set as Measured, then both BERs are the same but the Q factor is too high and does not match the formula.

do you know what is the algorithm that BER test set use?, because it is looks like the BER test set is following Measured algorithm.
