Overview
The Keysight Infiniium XR8 is a next-generation real-time oscilloscope — a multicore, 12-bit instrument scaling to 33 GHz — designed to accelerate high-speed digital and compliance testing. It runs the Infiniium 2026 software platform with faster response, improved stability and streamlined workflows.
Signal-integrity performance includes intrinsic jitter as low as 13 fs rms and noise below 130 µV at 8 GHz bandwidth, enabling reliable validation of USB4v2, DisplayPort 2.1 and DDR5, with jitter decomposition, PAM analysis and advanced equalization available in-instrument.
Key Benefits
12-bit acquisition at up to 33 GHz, 13 fs rms jitter and <130 µV noise for margin-rich measurement, and the Infiniium 2026 platform which cuts acquisition, analysis and reporting time.
Applications
High-speed serial compliance (USB4v2, DisplayPort 2.1), DDR5 memory validation, signal-integrity characterisation, and R&D debug of multi-gigabit links.
