Keysight Technologies, announced the launch of the UALink 1.0 (Ultra Accelerator Link) transmitter test solution, a dedicated compliance test tool designed for UALink devices. This cutting-edge test application enables high-speed validation within advanced computing and AI interconnect systems, automating critical electrical measurements to ensure signal integrity and compliance with the UALink 1.0 standard at 200 Gb/s link speeds.
Introduced in 2024 by the UALink Consortium, UALink 1.0 is an open standard engineered to meet the increasing bandwidth, scalability, and reliability demands of modern data centers. As AI workloads, cloud services, and smart devices continue to expand, traditional interconnect technologies like PCIe® and Ethernet are struggling to keep pace. UALink 1.0 represents a significant advancement, enabling rapid deployment of scale-up and scale-out silicon for AI communications in next-generation data center infrastructure.
Keysight’s UALink 1.0 transmitter test solution streamlines compliance testing by automating complex procedures. Tasks that previously required hours of manual work can now be completed in minutes using a Keysight UXR Real-Time Oscilloscope paired with the UALink 1.0 transmitter application.

Key Benefits of the UALink 1.0 Test Solution
-
Complete 200 Gb/s PAM4 transmitter tests in minutes instead of hours.
-
Accelerated high-speed transmitter validation for UALink devices.
-
Automated complex testing for UALink, backplane Ethernet, and cable Ethernet channels.
“The introduction of UALink marks a transformative leap in AI infrastructure and directly addresses the lack of an open, industry-standard, high-bandwidth low-latency interconnect for scaling AI accelerators within data centers. By providing tools for validating UALink transmitters, Keysight is helping the industry accelerate the introduction of products based on the open UALink standard. “, said Dr. Joachim Peerlings, Vice President of Network and Data Center Solutions at Keysight Technologies
Keysight will showcase the UALink compliance test solution at the 2025 OCP Global Summit, October 13–16 in San Jose, Calif., at booth #C1.
In addition, Keysight will unveil a 212 G receiver conformance test application (M8091DJCA) at the Summit. Designed for cable and backplane interfaces, this application supports foundational technologies of the UALink 200 Gb/s 1.0 standard and enables AI scale-up networking. The solution combines the Keysight M8050A 120 Gbd High-Performance BERT, Infiniium UXR Real-Time Oscilloscope, and the M8091DJCA compliance application to provide automated testing, enhanced measurement coverage, and streamlined calibration for conformance verification and debug.
