Keysight Expands PCIe® 7.0 Test Portfolio with New Receiver Stress Calibration

Key Terms

pcie 7.0 technical

PCIe 7.0 is the latest generation of the PCI Express standard, the high-speed electrical interface that lets core computer parts—processors, graphics cards, storage drives and network cards—move large amounts of data between each other. It matters to investors because each new PCIe version enables faster, more efficient servers and devices, spurs demand for upgraded chips and hardware, and can influence sales cycles, margins and competitive positions in semiconductors and data-center equipment; think of it as widening a digital highway to allow much higher traffic flow.

receiver stress calibration technical

Receiver stress calibration is the process of adjusting and testing a device that receives signals or measurements so it gives accurate, reliable readings when exposed to real-world stresses like high noise, temperature changes, or strong signals. For investors, it matters because proper calibration reduces product failures, regulatory problems, and warranty costs, and it increases customer trust and predictable performance—much like tuning a radio so it stays clear during a storm.

bert technical

BERT is a type of artificial intelligence model that reads and understands written text by looking at words in both directions, like reading a sentence forwards and backwards to catch the full meaning. Investors care because BERT lets companies automate reading of news, filings, customer feedback and regulatory documents more accurately, which can speed decision-making, improve compliance and surface signals that might affect a company’s outlook—similar to hiring a fast, very thorough analyst for large volumes of text.

bit error ratio tester technical

A bit error ratio tester (BERT) is a device or software tool that sends known patterns of digital data through a communications link and counts how many bits arrive incorrectly, producing an error rate that measures the link’s reliability. Investors care because this metric reveals whether networks, chips or products meet performance and quality standards—poor results can signal increased costs, recalls, slower rollout or customer problems, while strong results support product claims and lower operational risk.

asic technical

ASIC is Australia’s corporate, markets and financial services regulator that enforces rules for companies, financial advisers and market operators; think of it as the referee and rulebook keeper for financial activity. It matters to investors because ASIC’s oversight, investigations and enforcement actions affect company credibility, legal risk and market fairness—actions that can change stock prices, investor confidence and the safety of financial products.

common clock mode technical

A common clock mode is when multiple trading systems and data feeds use the same, synchronized time source so every trade and quote carries a uniform timestamp. For investors this matters because a shared clock makes the sequence of events clear, helps detect delays or manipulation, and supports fair, auditable markets—like everyone using the same stopwatch to prove who pressed the button first.

Addresses 128 GT/s receiver validation challenges for next-generation compute, AI, and data center applications

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) today announced a new PCIe^® 7.0 Receiver (RX) Test application, extending its PCIe 7.0 portfolio to enable end-to-end transmitter and receiver validation. The receiver test application addresses the growing challenge of validating receiver performance at 128 GT/s for next-generation compute, AI, and data center applications.

Keysight’s M8050A BERT system delivers the signal fidelity required for accurate and reliable PCIe® 7.0 receiver testing, helping customers validate receiver performance with high confidence.

As cycles between PCIe base specification releases continue to shorten and the PCIe 7.0 standard moves toward adoption, engineers face increasing challenges in validating receiver performance. These challenges are driven by a lack of test equipment dedicated to receiver testing, combined with increasingly complex stress signal calibration requirements.

At 128 GT/s, PCIe 7.0 receiver validation has become a defining hurdle for the industry. Reliable validation testing is essential to reduce risk and ensure interoperability as the ecosystem scales. Keysight’s receiver test solution enables engineers to validate devices with confidence.

Keysight’s M8050A BERT family, combined with the M8042A 120 GBaud pattern generator and M8043A error analyzer, meets the requirements for PCIe 7.0 receiver stress testing, enabling accurate signal generation and analysis for ASIC validation.

Complementing the hardware, the new N5991PB7A software reduces setup effort and accelerates receiver validation by simplifying the calibration and control of PCIe 7.0 receiver stress signals. Advanced automation capabilities enable more accurate and reliable ASIC receiver characterization.

Together, the hardware and software provide a comprehensive PCIe 7.0 receiver test solution that streamlines validation workflows, improves measurement confidence, and supports reliable ASIC development in common clock mode.

Among the key benefits of the new receiver stress calibration for PCIe 7.0:

• Accelerates Receiver Bring‑Up and Validation: Automated PCIe 7.0 RX workflows reduce manual setup and enable faster time‑to‑results.
• Reduces Compliance Risk at 128 GT/s: Specification‑aligned, stressed‑signal generation exposes receiver weaknesses early, minimizing late‑stage rework.
• Complements End‑to‑End PCIe 7.0 Test: When combined with Keysight’s PCIe 7.0 TX test solution, engineers gain comprehensive transmitter‑to‑receiver coverage.

Dr. Joachim Peerlings, Vice President of Network and Data Center Solutions at Keysight, said: “PCIe 7.0 receiver validation at 128 GT/s is one of the industry’s most significant signal integrity challenges. By extending our PCIe 7.0 physical‑layer measurement portfolio with advanced receiver characterization capabilities, we help customers reduce risk, accelerate development, and confidently validate next-generation ASIC designs.”

The PCIe 7.0 receiver test will be shown for the first time at the PCI-SIG^® Developers Conference in Santa Clara, Calif., May 6-7, 2026.
