Keysight Technologies推出了120千兆字节（GBD）高性能误码比率测试（BERT）系统，用于验证下一代芯片部署，可在最高1.6Tbit / s。

Digital development and senior validation engineers are challenged with higher loss and distortions when moving from 112 Gbps per lane to 224 Gbps per lane. The M8050A is designed to overcome these challenges with high signal integrity enabling more test margin. This allows customers to move to next generation 1.6T designs while maintaining the flexibility needed to quickly adopt the M8050A to new requirements in the future.

The M8050A BERT uses application-specific integrated circuit (ASIC) technology designed by Keysight to optimise the design to the requirements of the instrument. This higher integration simplifies setup and delivers reliable verification of designs at all speed grades with the combination of 120 GBd Pattern Generator, coupled with high signal integrity.

This can save time and investment by providing flexibility with license upgradeable hardware when test requirements change. Software extensions within the M8070B BERT system software open the application space to support upcoming technologies with full connection to automation software.

Keysight’s Infiniium 80 GHz UXR oscilloscope can be used as an acquisition-based Error-Analyser in combination with M8050A, provides a comprehensive bit error ratio tester up to 120 GBd that supports non return to zero (NRZ) and pulse amplitude modulation (PAM) 4, as well as PAM 6/8, which is likely required in 1.6T environment.

“从完全automated dark factories, closed loop digital twins to the metaverse, today’s applications and services generate vast amounts of artificial intelligence workloads. New electrical and optical designs are required to handle these workloads and make progress towards sustainability, achieving climate goals,” said Dr. Joachim Peerlings, vice president and general manager of Keysight’s Network and Data Centre business. “We are pleased with Keysight’s continuous efforts to deliver first-to-market solutions that support our customers in achieving these goals.”
