On October 10, 2025, Keysight Technologies announced the launch of the UALink 1.0 transmitter compliance test solution, a dedicated test application for the UALink 1.0 standard. The solution is designed to accelerate 200 Gb/s PAM4 transmitter testing for AI data‑center infrastructure, providing a rapid, automated path to validate high‑speed interconnects.
The UALink 1.0 standard, introduced in 2024 by the UALink Consortium, is an open interconnect standard that addresses the bandwidth, scalability, and reliability demands of AI data centers. The new test application automates critical electrical measurements, reducing manual testing from hours to minutes and ensuring signal integrity and conformance at 200 Gb/s link speeds.
Built around Keysight’s Infiniium UXR‑Series real‑time oscilloscopes and the D90203UAC UALink 1.0 transmitter compliance test application, the solution streamlines compliance testing with automated procedures that deliver rapid, repeatable results. Engineers can validate UALink devices more efficiently, shortening the design‑to‑deployment cycle.
Keysight will demonstrate the UALink compliance test solution at the 2025 OCP Global Summit in San Jose, California, from October 13‑16, where it will also unveil a 212 Gb/s receiver conformance application. The launch positions Keysight as a key enabler for the adoption of the UALink standard in AI data‑center networks.
