Keysight Infiniium UXR Series Oscilloscope Repair

Status: Current Production

Overview

The Keysight Infiniium UXR Series represents the ultimate in real-time oscilloscope performance, with bandwidths from 20 GHz to 110 GHz. The UXR features Keysight’s proprietary indium phosphide (InP) chipset for unmatched signal fidelity, 10-bit ADC at all bandwidths, and sample rates up to 256 GSa/s. DSOZ models provide the base platform while DSAZ models add advanced signal processing for enhanced measurement accuracy. The UXR is the instrument of choice for 400G/800G optical, PCIe Gen 5/6, USB4, DDR5, and other cutting-edge high-speed interface validation.

Common Keysight Infiniium UXR Failures We Repair

  • Ultra-high-bandwidth input sampler/amplifier damage from overvoltage
  • High-speed ADC calibration drift
  • Cooling system failures — critical for high-performance operation
  • SSD/storage failures in acquisition computer
  • Power supply module degradation under sustained load
  • Network interface failures
  • Display system failures

Our technicians perform component-level diagnostics on every Keysight Infiniium UXR unit. We identify and repair the specific failed components rather than replacing entire assemblies when possible, reducing your repair cost and turnaround time.

Calibration

Every Keysight Infiniium UXR repair includes NIST-traceable calibration. We verify all critical measurement parameters against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.

Who Uses the Keysight Infiniium UXR?

The Keysight DSOZ / DSAZ Infiniium UXR-Series Real-Time Oscilloscopes are used by semiconductor R&D, 400G/800G optical transceiver validation, PCIe/USB/DDR compliance, data center interconnect, coherent optics, and national research laboratories.
