• Software running on UXR scopes automates JESD239 testing with PAM3 SNDR, jitter and eye diagram analysis up to 48 Gbps. • Keysight Technologies, Inc. • announced its newgraphics 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. • 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.
