The M8050A is a high-performance BERT solution for validating next-generation chip deployments of up to 120 Giga Baud (GBd) for 1.6T (or one trillion bits per second) market with unachieved signal integrity, says the company. It is designed to help overcome the higher loss and distortion challenges faced by digital development and senior validation engineers when moving from 112 Gbps per lane to 224 Gbps per lane.

The M8050A’s high signal integrity enables more test margin, allowing users to move to next generation 1.6T designs while maintaining the flexibility needed to quickly adopt the M8050A to new requirements in the future.

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

The M8050A BERT delivers application-specific integrated circuit (ASIC) technology designed by Keysight to optimize the design to the requirements of the instrument. Key user benefits include:

  • A deep level of 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.
  • Saves 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 as an acquisition-based Error-Analyzer 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.
  • Keysight’s industry experts, coupled with a proven automation framework, deliver test consulting for the latest and emerging markets with close connection to standards bodies.

Simplified, time-efficient testing is essential when developing next-generation computer, consumer, or communication devices, says the company. Its M8000 Series is a highly integrated bit error ratio (BER) test solution for physical layer characterization, validation, and compliance testing. For more, see the company’s 1.6T solutions.
