Keysight Technologies M8040A 64 Gbaud BERT

Keysight Technologies has introduced the M8040A high-performance BERT for testing PAM-4 and NRZ devices. Engineers in validation labs and R&D who characterise receivers on the physical layer for the next generation of data centre interconnects will benefit from simplified test set-ups and repeatable results.

The highly integrated BERT supports PAM-4 signals up to 64 Gbaud and NRZ signals up to 64 Gbps. The pattern generator module provides built-in de-emphasis, jitter injection and an optional second channel. Engineers and designers can select PAM-4 and NRZ in the user interface, eliminating the need for external combiners, cabling and deskew to provide PAM-4 signals. The analyser module provides true PAM-4 error analysis in real time for long PRBS and QPRBS patterns. This allows for proofing even low bit error ratios and symbol error ratios with the required confidence.
