ML4079E 8 Channel | 56 GBd PAM4 & NRZ | 800G BERT 8 x 56 GBd NRZ/PAM4 BERT | SSPRQ, PRBS13Q & PRBS31Q | TX and RX Equalizers | Real FEC analysis | Gearbox cables testing The early adoption of 800G brings new considerations for companies on the cutting edge. The exponential increase in data transfer speeds has resulted in higher Bit Error Rates, and a keen understanding of system functionality is crucial. Bit Error Rate Testers (BERTs) have therefore become a cornerstone of physical layer testing. From testing fiber optic and copper wire digital data transmission lines to testing signal integrity of transceivers, these instruments ensure the validity of the devices at the heart of data centers all over the world. The ML4079E is an 800G BERT tailored to the needs of those looking to transition to an 800G environment with minimal hassle. This BERT supports the newly emerging 8x100 Gbps fiber-optic technology and the increasingly crucial real hardware FEC analysis to understand how your DUT will behave in a real data center environment. The ML4079E features signal to noise ratio (SNR) and histogram measurements, and allows the user to implement transmitter and receiver equalizers. The ML4079E can also be used to optimize link performance to be able to minimize the ever-more important power consumption of high-speed connections. The ML4079E can be combined with the ML407-PAM jitter clock source for jitter tolerance testing.

ML4079E8 x 56 GBd PAM4 BERT Introduction The ML4079E is a full featured 800G BERT that can be configured as eight channels of 23-29 and 46-58 GBaud PAM4 or 23 - 29 and 46 - 58 Gbps NRZ. • Real hardware FEC. Pre- and post-FEC BER/SER, and FEC margin available on channels individually as well as on 100G, 400G, 800G blocks Available patterns: The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ, PRBS31Q, etc. Additionally, the user may program the TX to output a user-defined pattern. The ML4079E supports real hardware FEC, with th e following FEC modes:...
