13~110GHz analog bandwidth range model
Suitable for PAM4, 5G, satellite communication, and optical design
↓Noise floor, ↑Vertical resolution
On the 19th, Keysight Technologies announced the Infinium UXR series oscilloscopes featuring models with an analog bandwidth range from 13 GHz to 110 GHz. The new products are a stable investment capable of meeting high signal integrity and future technological advancements.

Keysight's new Infinium UXR series supports comprehensive, high-margin designs, enabling high-speed serial and optical designers focused on next-generation technologies to accelerate time-to-market. Furthermore, with a combination of superior performance levels and diverse bandwidth options, the Infinium UXR series is a suitable solution for engineers and designers working with PAM4, 5G, satellite communications, and optical designs, as well as all generations of DDR, USB, PCIe, or other serial technologies.

Keysight's new Infinium UXR series provides a low noise floor and high vertical resolution, ensuring that oscilloscope noise does not affect measurements and that signals are accurately represented. As a result, the eye diagram becomes much clearer, and accurate margins and performance can be determined.

With Keysight Infinium UXR Series 13–110 GHz oscilloscope models, designers can shorten time-to-market with the following features: Faster conformance testing is possible with 10-bit vertical resolution and high signal integrity and margin for excellent effective bit count (ENOB).
In addition, it supports up to four full-bandwidth channels with an intrinsic inter-channel jitter of less than 35 fs (rms), accurately reconstructing high-speed signals with a sampling rate of 256 GSA/s per channel in the 40–110 GHz models and 128 GSA/s per channel in the 13–33 GHz models, providing accurate timing and skew measurements. An optional factory-grade self-calibration module ensures consistent measurement accuracy while minimizing equipment calibration time, and the chipset, based on Keysight's patented Indium Phosphate (InP) process, enables very wide bandwidth and very low noise floor performance.

In addition to this, Keysight announced two additional solutions: the N4391B Optical Modulation Analyzer (OMA) solution and the M8194A 120 GSa/s Arbitrary Waveform Generator (AWG) solution. When used with the company's Infinium UXR series oscilloscopes, these solutions provide everything from simulation to analysis for PAM4 and 400G, 600G, and terabit coherent optical interconnect designs.

Dave Cipriani, Vice President of Keysight’s Digital and Photonics Center, said, “As the development of terabit and 5th generation serial technology accelerates, high-speed serial and optical technologies are continuously raising the boundaries of speed and performance,” adding, “The expanded UXR oscilloscope series, UXR-based OMAs, and Keysight’s fastest AWGs provide high-speed designers with unprecedented end-to-end solutions to rapidly advance today’s technology developments, while also providing future investment protection.”
