Keysight Technologies has launched its next-generation Infiniium XR8 real-time oscilloscopes to accelerate high-speed digital and compliance testing while improving efficiency and insight for modern electronics development. As interface standards such as USB, DisplayPort, and DDR continue to evolve in speed and complexity, engineers are facing tighter margins, higher data rates, and compressed development timelines. These pressures often lead to longer validation cycles, reduced noise tolerance, and increasing lab constraints. The Infiniium XR8 addresses these challenges with a new hardware and software architecture optimized for high-speed digital applications and emerging standards, enabling engineering teams to condense days of testing into hours.
The XR8 integrates newly designed front-end ASIC technology with an integrated ADC and DSP digital engine to preserve signal integrity, enhance timing accuracy, and deliver consistent, repeatable measurements across high-speed serial, memory, and mixed-signal designs. These capabilities are crucial for debugging and validating high-speed interfaces, where even small signal impairments can significantly impact system performance and compliance margins.
A redesigned mechanical architecture further improves usability by reducing system power consumption, enhancing thermal efficiency, and minimizing acoustic noise within a compact footprint. This allows engineers to deploy high-performance oscilloscopes in space-constrained labs and dense validation environments while maintaining stable, low-noise operation.
Powered by Keysight’s new The Infiniium 2026 software platform, the XR8, delivers faster response times, improved stability, and streamlined workflows for high-speed digital and compliance testing. The updated user experience features flexible waveform windows, enhanced visualization, and productivity tools, including drag-and-drop functionality and an integrated SCPI recorder. Optimized multithread processing and memory management support advanced measurement capabilities, including enhanced jitter decomposition, PAM analysis, and advanced equalization for deeper insight and faster validation.
According to Keysight, the combined hardware and software architecture enables maximized test margin and signal integrity, with intrinsic jitter as low as 13 fs rms and noise performance below 130 µV at 8 GHz bandwidth. This supports confident validation of high-speed interfaces, including USB4v2, DisplayPort 2.1, and DDR5.
The new ADC and DSP digital engine, together with the Infiniium 2026 software, accelerates acquisition, analysis, and reporting by up to three times, significantly reducing validation cycles and improving overall test throughput. Lower power consumption, improved thermal design, and reduced acoustic noise also create a smaller and more flexible platform that can be positioned closer to the device under test.
Jun Chie, vice president, Keysight Product Management, said, “Our customers are under intense pressure to validate increasingly complex, high-speed designs on compressed schedules. The Infiniium XR8 directly addresses that reality, preserving signal fidelity, accelerating compliance workflows, and reducing lab constraints in a single, streamlined platform. It’s about giving engineers back time, confidence, and productivity when they need it most.”
