Shortens Joint Electron Device Engineering Council standard validation cycles for graphics and AI systems requiring high-speed memory interfaces
SANTA ROSA, Calif., FEBRUARY 17, 2026
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.
Keysight sets the standard with SNDR measurements that validate PAM3 signaling performance amid crosstalk and complex system challenges, enabling confident high-speed innovation.
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 Probe, 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:
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.

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.
