Agilent/Keysight M8062A

The Keysight M8062A is a 32 Gb/s BERT front-end module that extends the M8020A Bit Error Ratio Tester for high-speed serial link characterization. This 2-slot AXIe module delivers integrated generator and analyzer capabilities up to 32.4 Gb/s, supporting NRZ line coding with full jitter injection, de-emphasis, ISI generation, and analyzer equalization. Engineers use the M8062A for R&D validation of 100G class links, Thunderbolt 3, SAS 24G, data center interfaces, and long-haul communication standards.
