New validation solutions enable data center operators to overcome bandwidth, latency, and interoperability challenges as AI infrastructure scales

Keysight Technologies, Inc. (NYSE: KEYS) introduced a new portfolio of scale-up validation solutions designed to help artificial intelligence (AI) data center operators address growing bandwidth, latency, and interoperability bottlenecks as compute clusters become denser and more complex. The solutions support emerging and established interconnect standards, including UAlink™200G, PCIe^® 7.0, PCIe^® 6.0, PCIe^® 5.0, and CXL™ 3, enabling faster deployment of high-performance, energy-efficient AI infrastructure.

Keysight receiver conformance test software for UALink 200G complements its UALink transmitter test solution.

Rapid AI adoption is driving unprecedented demand for high-density compute, real-time data movement, and low-latency memory access. As hyperscalers and enterprises scale-up AI infrastructure, reliable validation of high-speed interconnects is critical to sustaining performance while controlling cost and energy consumption.

Keysight addresses these scale-up challenges with five new solutions:

Keysight Receiver Conformance Test Software for UALink 200G

Keysight UALink™ 200G receiver conformance test software accelerates validation of UALink™ 200 Gb/s interfaces critical to AI scale-up networking. By integrating the Keysight M8050A 120 Gbd High-Performance BERT and Keysight Infiniium UXR Real-Time Oscilloscope, the solution simplifies the stressed-signal calibration and delivers comprehensive measurement coverage for fast, reliable conformance testing and debugging.

Keysight PCIe 7.0 Transmitter Test

As AI and machine learning workloads scale, demand for ultra-high bandwidth interconnects continues to grow. Keysight’s PCIe 7.0 Transmitter Test solution enables comprehensive PCIe 7.0 BASE specification compliance testing at speeds up to 128GT/s, helping customers accelerate adoption while next-generation AI accelerators and network devices reduce integration risk in future AI infrastructure.

Keysight Protocol Compliance Test Suite for PCIe 6.0

Keysight’s PCIe 6.0 Protocol Compliance Test Suite provides end-to-end validation of link and transaction layer requirements at speeds up to 64 GT/s. Built on the Keysight-proven PCIe 6.0 protocol platform, the solution combines advanced exerciser and analyzer hardware with automated test execution and clear pass / fail reporting. This streamlined approach reduces debug time and accelerates compliance testing for next-generation designs.

Keysight CXL 3 Protocol Exerciser and Analyzer Test Solution

CXL 3 addresses critical data center challenges by expanding memory capacity and bandwidth beyond the limits of traditional DIMMs for memory intensive AI and data workloads. The interconnect enables high bandwidth, low-latency memory sharing across heterogenous compute platforms for more efficient resource utilization. Keysight’s CXL 3 protocol solution validates coherent memory pooling across CPUs, GPUs, and accelerators, enabling scalable performance and future-ready architectures for disaggregated compute environments.

Keysight PCIe 5.0 Protocol Link and Transaction Compliance Solution Certified by PCI-SIG

As operators scale high-density compute environments, validating compliance to the PCIe specification becomes nonnegotiable. Keysight’s automated PCIe protocol compliance solution, now certified by PCI‑SIG for PCIe 5.0 link and transaction layer testing of endpoint and retimer devices, accelerates standards‑based validation and shortens time-to-deployment. By validating compliance‑vendor interoperability early, Keysight helps data center operators scale with confidence while reducing risk and cost.

Dr. Joachim Peerlings, Vice President and General Manager, Network and Datacenter Solutions, Keysight, said: “As AI demand outpaces how quickly operators can bring power and fiber online, the real hurdle is scaling high bandwidth, low latency interconnects without sacrificing efficiency or interoperability. Keysight’s scale-up solutions help the industry validate performance, energy efficiency, and reliability across standards before deployment.”

The new scale-up solutions will demonstrated at DesignCon 2026, February 24-26, at booth number 1039.
