Milpitas, Calif. – September 19, 2026 -- Teledyne LeCroy has released the Summit Z74 Protocol Exerciser, the industry's first standalone test tool for PCIe 7.0 technology, targeting the accelerating validation needs of AI, high-performance computing, cloud, and advanced storage systems.
PCIe 7.0 doubles data rates to 128.0 GT/s, straining existing validation tools
The PCIe 7.0 specification doubles the raw data rate of PCIe 6.0 from 64.0 GT/s to 128.0 GT/s, delivering up to 512 GB/s of bi-directional bandwidth in a x16 configuration. At these speeds, PAM4 signaling and FLIT-based protocol architectures demand test equipment capable of generating precise protocol traffic and providing deterministic control over link behavior.
Summit Z74 operates standalone or pairs with existing Summit M616 analyzer
Used independently, the Summit Z74 lets engineers generate controlled protocol traffic and exercise device behavior under targeted conditions. Paired with the Summit M616 Protocol Analyzer, it forms a complete system combining traffic generation with protocol capture, decode, analysis, and debug for link training behavior, transaction-level issues, LTSSM transitions, and interoperability challenges.
PCI-SIG president says protocol test tools speed ecosystem readiness
Al Yanes, PCI-SIG President and Chairperson, said protocol test equipment accelerates validation and ecosystem readiness as engineers address growing system complexity tied to the PCIe 7.0 rollout.
Teledyne LeCroy positions dual-mode design to protect customer test investment
Michael Romm, General Manager of Teledyne LeCroy's Protocol Solutions Group, said the flexibility of deploying the Summit Z74 standalone or alongside the Summit M616 helps customers protect existing test investment while advancing next-generation PCIe designs within a familiar Summit workflow.
The Summit Z74 and Summit M616 are available now to PCI Express development teams preparing for PCIe 7.0 validation programs.
