Hi Alistu’
thanks for your reply, as you can see I use also BER test set, the BRE is almost the same in BER analyser and BER test set. so the problem is in how BER analyser is calculating the Q factor.
I notice that in the result of BER test set has the ability to add something, is that mean we can add a function that use the result of the BER test set to produce another thing such as Q factor, or what is that mean?
