Hi Brian,
Thanks a lot for your prompt answer. I have in mind is that, for example, if we assume that the full sequence of the 2^7-1 PRBS were to be represented by a 5-bit number, say 01110. After the first 5 bits has been generated by the PRBS generator, then the same sequence will be repeated. So, it will be 01110 01110 01110 and so on. So, it will become not a PRBS anymore, given that the bits are random only in the 5 bits. However, 10^-12 BER means that we need to input the error analyzer with more than 10^-12 bits and then check the error bits. But the PRBS length is much lower than the number of bits that 10^-12 BER used. So, I am confusing about this measurement. How does it imply clearly ...
