The Keysight Infiniium UXR-Series oscilloscopes deliver world-leading performance, ultra-low noise, and high signal fidelity for you to truly see and understand the fastest phenomena – enabling you to develop the next generation of technology and research more quickly
More Accurate Analysis
Up to four channels of simultaneous 110 GHz of bandwidth, each channel is concurrently sampling at a rate of 256 GSa/s with 10 bits of high-definition Analog to Digital Converter (ADC) resolution
Runs Faster
The UXR-Series is up to 100x faster, enabled by a powerful new measurement acceleration application specific integrated circuit (ASIC) chip and memory controller capable of five trillion integer operations per second (IOPS
Fully Upgradeable
The Infiniium UXR-Series is scalable — you can easily upgrade the bandwidth, memory, channel count, and software capabilities to meet your future needs
Best Signal Integrity
The Infiniium UXR-Series oscilloscopes help you see what’s really happening in your design with the industry’s lowest noise and jitter measurement floor. This functionality means less scope noise in your measurements and a truer depiction of your signal
• Lowest noise
- <860 μV RMS at 110 GHz
- <500 μV RMS at 70 GHz
- <266 μV RMS at 33 GHz
• Lowest intrinsic jitter
- 25 fsRMS
• Lowest interchannel jitter
- 10 fsRMS
• Highest effective number of bits (ENOB)
- 5.0 bits at 110 GHz
