MEASUREMENT TOOLS Keysight introduces Infiniium XR8 oscilloscopes for faster high-speed validation

Keysight Technologies, launched its next-generation Infiniium XR8 Real-Time oscilloscopes, designed 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 rapidly evolve and scale in speed and complexity, engineers face tighter margins, higher data rates, and compressed development timelines. These pressures result in longer validation cycles, reduced noise tolerance, and growing lab constraints. The Infiniium XR8 addresses these challenges with a completely new hardware and software architecture optimized for today’s high-speed digital applications and emerging standards, helping engineering teams condense days of testing into hours.

The XR8 integrates newly designed front-end ASIC technology and an integrated ADC and DSP digital engine to preserve signal integrity, improve timing accuracy, and deliver consistent, repeatable measurements across high-speed serial, memory, and mixed-signal designs. These capabilities are essential for debugging and validating today’s high-speed interface, where small impairments in signal quality can directly impact system performance and compliance margins.

A redesigned mechanical architecture further enhances usability by reducing system power consumption, improving thermal efficiency, and minimizing acoustic noise with a compact footprint. Engineers can deploy high-performance oscilloscopes in space-constrained labs and dense validation environments while maintaining a stable, low-noise operation.

Powered by Keysight’s new Infiniium 2026 software platform, the XR8 delivers faster response time, improved stability, and streamlined workflows for high-speed digital and compliance testing. The modern user experience features flexible waveform windows, enhanced visualization, and productivity tools such as drag‑and‑drop functionality and an integrated SCPI recorder. Optimized multithread processing and memory management enables engineers to fully leverage Keysight’s measurement science, delivering enhanced jitter decomposition, PAM analysis, and advanced equalization for deeper insight and faster validation.

Together, the new hardware and software architecture enables:

• Maximized test margin and signal integrity: Intrinsic jitter as low as 13 fs rms and noise performance below 130 µV at 8 GHz bandwidth provide exceptional fidelity and preserved compliance margin, enabling confident validation of high-speed interfaces including USB4v2, DisplayPort 2.1, and DDR5.

• Accelerated compliance testing efficiency:A new ADC and DSP digital engine combined with Infiniium 2026 software accelerates acquisition, analysis, and reporting by up to three times, dramatically reducing validation cycles and improving overall test throughput.

• Compact, quiet, and flexible lab deployment: Lower power consumption, enhanced thermal design, and reduced acoustic noise create a smaller, more flexible platform that can be positioned closer to the device under test while supporting comfortable, distraction-free daily engineering workflows.

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.”
