Keysight Technologies has launched its new graphics double data rate 7 (GDDR7) transmitter compliance solution, which is expected to speed up the validation of Joint Electron Device Engineering Council (JEDEC) standards for advanced graphics and artificial intelligence applications.
The increasing demand for high-performance computing, gaming, and AI applications is pushing the memory and GPU industry to adopt GDDR7 technology. But this shift also brings new challenges in terms of validation and interoperability. The adoption of pulse amplitude modulation (PAM3) encoding from traditional NRZ signaling in GDDR7 technology improves the bandwidth and simplifies the channel, but it also requires new methods of measurement and testing to preserve signal integrity at such high speeds. Keysight’s GDDR7 transmitter compliance solution is specifically designed to meet these challenges.
The Keysight GDDR7 transmitter test solution includes D9370GDDC software running on Keysight’s UXR oscilloscope series, automating debug and characterization of GDDR7 transmitter designs to verify compliance with JEDEC JESD239 requirements. When combined with the InfiniiMax Ultra Probe Amplifier, 25 GHz probe, the solution delivers precise PAM3 signal analysis and timing measurements, helping engineers validate and optimize high-speed memory transmitters for next-generation GPUs and memory devices.

Key benefits of the Keysight GDDR7 transmitter compliance solution include:
Enables PAM3 signaling validation in real-world environments: Enhanced signal-to-noise-and-distortion ratio (SNDR) measurements take into account crosstalk, making it possible to identify and fix signal integrity problems earlier in the design cycle.
Reduces validation time and risks: The automated compliance validation process removes the need for manual configuration and setup, ensuring consistent and repeatable results for electrical, timing, jitter, and eye diagram parameters, thus enabling faster and more reliable JESD239 compliance.
Design with confidence at 48 Gbps: A low-noise measurement floor enables accurate jitter, electrical, and timing analysis of PAM3 encoding, helping engineering teams confidently validate next-generation high-speed interfaces and meet aggressive performance targets.
The GDDR7 test solution can be deployed alongside Keysight’s UXR oscilloscope and the MX0025A InfiniiMax Ultra Probe Amplifier, 25 GHz probe to support comprehensive system debug, validation, and characterization workflows.
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.”
