The device can measure high frequency signals while supporting debug and compliance in advanced interface standards
Keysight Technologies has introduced the Infiniium XR8 real time oscilloscopes for high speed digital validation and compliance testing. The series combines updated hardware architecture with the Infiniium 2026 software platform to address increasing data rates, shrinking signal margins, and compressed development timelines.
As interface standards such as USB4, DisplayPort 2.1, and DDR5 continue to evolve, validation requirements are becoming more demanding. Higher speeds and tighter tolerances reduce noise margins and increase the complexity of jitter and timing analysis. The XR8 series is positioned to support these measurement challenges in serial, memory, and mixed signal designs.
The platform integrates a redesigned front end ASIC along with an integrated ADC and DSP digital engine. This architecture is intended to maintain signal integrity and improve timing accuracy across high speed interfaces. Intrinsic jitter is specified as low as 13 fs rms, with noise performance below 130 µV at 8 GHz bandwidth.
A revised mechanical design reduces power consumption and acoustic noise while improving thermal efficiency within a compact footprint. This allows the instruments to be deployed in space constrained laboratory environments and positioned closer to the device under test.
The oscilloscopes operate on the Infiniium 2026 software platform, which introduces multithread processing, updated waveform window management, and an integrated SCPI recorder to support measurement workflows and automation.
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.”
