Bit Error Rate Testing

The iScope BER Testing can be performed to evaluate the performance of FEC or test the BER of any communication channel such as SERDES or wireless, forward error correction (FEC) bit error rate (BER) testing is performed by modulating data pattern with Additive White Gaussian Noise (AWGN), and feeding it into the system, then calculating the BER based on the number errors the system corrected. There are two mechanisms in the iScope to perform BER test, either using the SW utility provided with the iScope SW, or using a Plug-In hardware accelerated noise generator. The HW accelerated noise generator, is used when it is required to perform tests at extremely low BER (down to BER 10-15).
