Keysight Technologies Releases XR8 Real-Time Oscilloscope Platform and Infiniium XR804KA

Editor's Note: On March 5, 2026, Keysight Technologies grandly held a launch event in Beijing for its all-new XR8 real-time oscilloscope platform and Infiniium XR804KA, the first product based on that platform. As signals get faster, noise gets smaller, and testing gets more complex, the XR8 is like a "precise and efficient partner," using technological innovation to break through measurement bottlenecks and leveraging full-dimensional capabilities to support industry progress. In this era where AI-driven technological iteration has entered exponential growth, what exactly should an oscilloscope truly "born for AI" look like?

Looking back at the evolution of test and measurement technology, from the first digital oscilloscope, the HP54500A, in 1989, to the first InP oscilloscope, the 90000X, in 2010, and then to the 110 GHz oscilloscope, the UXR, in 2018, Keysight has always "anticipated industry needs through technology."

Today, the world is in an era of technological explosion where "speed and complexity rise together." From PCIe6's 32 Gbaud PAM4 in 2022 to PCIe8's ultimate goal of 128 Gbaud in 2028, the iteration cycle for high-speed bus standards has shortened to 1-2 years; USB has already evolved to the latest USB4v2 at 80 Gbaud, and the DDR and GDDR series are breaking through transmission limits at a pace of "generational leaps."

Ren Yannan, General Manager of Marketing for Keysight Greater China, pointed out that the surge in transmission rates has brought about a fundamental change in signal modulation methods. This means that any electromagnetic interference of even a few microvolts, or any transmission loss, could cause signal distortion, and the measurement accuracy and noise suppression capabilities of traditional oscilloscopes have already hit the "ceiling."

Traditional oscilloscopes, based on hardware architectures of discrete devices and software platforms that have been used for more than two decades, can no longer adapt to future technological needs. The industry needs a next-generation test platform that is rebuilt from the ground up and truly oriented toward the future.

Now, the XR8 has arrived.

As a new-generation high-performance oscilloscope platform, the XR8's core breakthrough stems from a full-stack innovation "from chip to architecture." This is by no means simple parameter stacking, but a deep reconstruction of the essence of measurement.

Higher integration: reconstructing the hardware architecture with a "single-chip mindset"

The new XR8 oscilloscope platform has achieved a fundamental breakthrough at the architecture level, especially in the most critical front-end design.

A traditional discrete front end consists of multiple devices and complex routing, whereas the XR8 innovatively adopts a single highly integrated front-end ASIC, integrating the preamplifier and analog sampler on the same chip and enabling direct connection to the interface. This design greatly shortens the signal path, reduces conversion stages, and significantly lowers routing loss in high-frequency applications, improving signal integrity from the source. By capturing a purer and more accurate input signal at the very first moment, the XR8 lays a solid foundation for the overall measurement accuracy of the instrument and demonstrates higher measurement fidelity and consistency in high-speed and high-bandwidth test scenarios.

The XR8 has also achieved a revolutionary upgrade in the digital acquisition system. The new-generation highly integrated 12-bit ADC integrates the ADC, DSP, memory control, and buffering functions that were originally distributed across multiple ASICs into a single-chip architecture, which not only greatly improves system integration but also significantly reduces size and power consumption. Compared with the previous-generation multi-chip solution, the XR8 reduces system complexity and potential failure points while achieving a more compact overall design and better thermal management performance. This comprehensive innovation from analog to digital enables the XR8 to lead across the board in measurement accuracy, system efficiency, and engineering reliability, providing a more powerful test platform for next-generation high-speed electronic design and verification.

In terms of hardware architecture, the new XR8 platform has completed a revolutionary leap from "discrete" to "integrated," ultimately delivering systematic benefits of "30% depth reduction, one-third lower power consumption, and 4x lower noise."

Faster speed: achieving a leap of 3-10x

The combination of the XR8's multi-core CPU parallel processing and optimized firmware delivers a leap of 3-10x in analysis performance: SNDR analysis is 10x faster, DDR5 test time is compressed from 40 minutes to 13 minutes, and DP2.1 compliance testing is shortened from 7.5 hours to 2.5 hours.

This means engineers can complete in one day test tasks that previously took two days, investing more time in design optimization rather than waiting for results.

Comprehensive hardware specification upgrades: building a performance moat

The hardware parameters of the XR8 oscilloscope platform have achieved "all-dimensional leapfrogging." The core of the hardware upgrade is the perfect synergy between the native 12-bit high-precision ADC and industry-leading ENOB (effective number of bits) performance. Compared with the industry-mainstream 8-bit and 10-bit ADCs, the 12-bit quantization level reaches 4096 levels, 16 times that of 8-bit devices and 4 times that of 10-bit devices. It can push the discrete resolution of signal amplitude from the millivolt level to the hundreds-of-microvolts level, accurately restoring the inherently narrow four electrical levels in PAM4 signals and completely avoiding the drowning of weak signal details by quantization error.

At the same time, the XR8 achieves system-level ultra-low noise through RF front-end ASIC integration and refined circuit layout design. This feature is especially important in high-speed signal testing with low noise margins such as PAM4. It can also stably capture extremely weak microwave time-domain signals below -80 dBm, clearly separating tiny jitter components and weakly coupled crosstalk signals in high-speed interconnects. Even under extremely small noise margins, it can restore clean eye diagrams without distortion, fundamentally avoiding test misjudgments caused by noise interference.

Software innovation: integrating "intelligence" into every detail

The XR8's innovation goes beyond hardware parameters; it also lies in a full-link experience upgrade from architecture to software, truly realizing that "high performance does not mean a high barrier."

The new-generation software platform carried by the XR8 integrates "intelligence" into every operational detail: enhanced visualization features make complex eye diagrams and jitter histograms clear through color grading, so even beginners can quickly identify key indicators; the intelligent SCPI application supports command screen recording and playback, and together with built-in waveform generation simulation, greatly shortens the development cycle of automated test flows and significantly reduces the learning cost. This design of "backward-compatible technology and upward-upgrading experience" allows engineers of different experience levels to get started quickly, truly achieving "letting tools adapt to people, rather than people adapting to tools."

From the perspective of application scenarios, the XR8's "versatile" attributes precisely match today's complex R&D needs. In the development of high-speed computing chips and advanced interconnects, it can decompose the tiny jitter and amplitude distortion of 10 Gbps signals, providing data support for chip design optimization; in automotive radar anti-interference testing, when facing the superimposed interference echoes of same-frequency FMCW radars, the XR8's excellent noise floor and dynamic range can separate true and false target signals, avoiding speed misjudgments and target flicker and safeguarding autonomous driving safety; in complex embedded systems, it can simultaneously cover the measurement needs of DC, kHz servo, MHz sensing, and GHz high-speed interconnects, and through functions such as FFT analysis and channel simulation, solve the measurement challenges of "high speed + weak signals + noisy environments" in one stop. It can be said that with the arrival of the XR8, engineers, at a time when "signals are approaching physical limits," have for the first time a measurement experience of "long-term stability + ultimate precision."

Postscript: Today's XR8 is not only an inheritance of past technological accumulation, but also a forward-looking layout for the future. Its advanced interconnect architecture and 12-bit DSP/ADC design have already reserved adaptability for next-generation high-speed buses such as PCIe 8 and GDDR7X, allowing the device lifecycle to far exceed that of a single product cycle and providing users with long-term investment value.
