The ML4079EN is an 800G BERT ready to support the newly emerging 8 x 100 Gbps technology cycle. Most importantly it supports real hardware FEC analysis to be able to understand the DUT behavior in a system environment. Other features include signal-to-noise ratio (SNR) and histogram measurements, as well as transmitter and receiver equalizers. ML4079EN has uniquely integrated jitter and noise injection to support IEEE JTOL and ITOL measurements.
