Keysight Introduces PAM3 Signaling with New GDDR7 Transmitter Compliance Solution for Next-Generation Graphics Memory

Key Terms

gddr7 technical

GDDR7 is the next-generation type of high-speed memory used mainly in graphics processors and other chips that need to move large amounts of visual data quickly. Think of it as a wider, faster highway that lets images, video and AI calculations flow with less delay and lower power use. Investors watch GDDR7 adoption because it can boost performance of devices, affect component costs and margins, and influence competitiveness and sales cycles across the chip and hardware supply chain.

pam3 technical

Pam3 is a small, man‑made molecule used in biomedical research to trigger the body’s early immune alarms; it mimics a piece of bacteria to activate innate immune sensors. Investors should care because it is often used as an immune stimulant or vaccine ingredient (an adjuvant) in drug development studies, and results involving pam3 can influence clinical readouts, regulatory review and the perceived value of biotech programs—like flipping a test switch to see if an immune approach works.

joint electron device engineering council technical

An industry standards organization that creates technical rules and test methods for semiconductor memory, microelectronics, and related components. Think of it as a rulebook manufacturers follow so different chips and devices work together reliably; when JEDEC sets or updates a standard, it can affect product compatibility, production costs, and time-to-market—factors investors watch because they influence a company’s ability to sell hardware and scale manufacturing.

jedec technical

JEDEC is an industry standards organization that sets common rules and technical specifications for semiconductor components like memory chips, ensuring products from different makers fit and work together. For investors, JEDEC standards matter because they reduce risk and cost by promoting compatibility and quality across the supply chain—think of it as a building code for electronics that helps products get adopted more quickly and makes manufacturing and buying decisions more predictable.

oscilloscope technical

An oscilloscope is an electronic test instrument that displays how electrical signals change over time, like a seismograph that shows tremors but for voltages and currents. Investors care because companies that design, build or use complex electronics rely on oscilloscopes for product development, quality control and troubleshooting, so demand and spending on these instruments can signal R&D intensity, manufacturing health and potential revenue streams.

Shortens Joint Electron Device Engineering Council standard validation cycles for graphics and AI systems requiring high-speed memory interfaces

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) announced its new graphics double data rate 7 (GDDR7) transmitter compliance solution, that accelerates validation of Joint Electron Device Engineering Council (JEDEC) standards for graphics and artificial intelligence (AI) applications.

The D9370GDDC GDDR7 transmitter compliance test software running on a Keysight UXR oscilloscope accelerates transmitter testing by automating compliance validation, enabling faster and more accurate test results.

Growing demand for high-performance computing, gaming, and AI platforms is driving memory and GPU vendors to adopt GDDR7, but the transition is creating significant validation challenges. GDDR7's shift from traditional NRZ to pulse amplitude modulation (PAM3) encoding enables higher bandwidth while reducing channel complexity, but it requires new test approaches to ensure signal integrity and interoperability at ultra-high data rates. Keysight’s GDDR7 transmitter test solution addresses this bottleneck, enabling organizations to validate designs while accelerating time-to-market.

The Keysight GDDR7 transmitter test solution consists of D9370GDDC software that runs on Keysight’s UXR oscilloscope series and automates debug and characterization of GDDR7 transmitter designs to ensure compliance with JEDEC JESD239 specifications. When paired with the InfiniiMax Ultra Probe Amplifier, 25 GHz, the solution enables accurate PAM3 signal analysis and timing measurements, allowing engineers to validate and optimize high-speed memory transmitter designs for next-generation GPUs and memory devices.

Key benefits of the Keysight GDDR7 compliance test solution include:

• Validates PAM3 signaling under real-world conditions: Advanced signal-to-noise-and-distortion ratio (SNDR) measurements account for crosstalk, enabling engineers to identify and resolve signal integrity issues.
• Reduces validation time and risk: Automated compliance testing eliminates manual setup and configuration while delivering consistent, repeatable measurements across electrical, timing, jitter, and eye diagrams, helping teams achieve JESD239 compliance faster and with fewer errors.
• Design with confidence at 48 Gbps: A low noise measurement floor enables accurate jitter, electrical, and timing analysis of PAM3 encoding, empowering customers to validate next-generation high-speed interfaces reliably and meet performance targets faster.

The GDDR7 test solution can be paired with Keysight’s UXR oscilloscope and MX0025A InfiniiMax Ultra Probe Amplifier, 25 GHz for system debug, validation, and characterization.

Dr. Joachim Peerlings, Vice President and General Manager, Network and Datacenter Solutions, Keysight, said: “By bringing precise, PAM3-aware SNDR measurements to GDDR7 compliance, Keysight is helping the industry shorten validation cycles, reduce interoperability risk, and deliver reliable bandwidth despite increasingly complex channels.”

The new solution will be demonstrated at Keysight’s booth (#1039) at DesignCon 2026, Feb. 24-26.
