In the laboratory, an engineer repeatedly adjusts the high-speed signal link, but the waveform on the oscilloscope screen remains jittery—this is a common dilemma faced by many Chinese electronic R&D teams.
“Bandwidth breaks through 90GHz, ranking first in the country and second in the world.”
On October 15, at the 2025 Bay Chip Expo, this statement by Liu Sang, CEO of Wanliyan Technology Co., Ltd., a subsidiary of Xinkailai, caused a sensation in the audience. This newly released ultra-high-speed real-time oscilloscope directly targets the high-end market, which has long been dominated by Western giants.
01 Technological Breakthrough: The “Breakthrough Moment” for Domestic Oscilloscopes
In the field of electronic testing and measurement, oscilloscopes are known as the “eyes of electronic engineers.” However, the cutting-edge technology of these “eyes” has long been firmly controlled by Western brands such as Keysight Technologies and Tektronix.
A R&D director who has worked in a communications company for fifteen years admitted: “All the oscilloscopes we previously purchased with bandwidths over 50GHz were imported, which not only had high prices and long waiting periods, but some advanced models were also subject to export controls.”
The pain of being “choked” is particularly evident in the high-end testing instrument sector.
The 90GHz bandwidth oscilloscope released by Wanliyan has achieved three major core technological breakthroughs:
Ultra-wideband analog front-end architecture that solves the world-class problem of ultra-high frequency signal acquisition;Patented sampling technology that ensures signal fidelity while maintaining ultra-high sampling rates;Self-developed chipsets that achieve autonomy from the source.
The performance specifications of this oscilloscope are impressive:Real-time sampling rate exceeds 240GSa/s, storage depth reaches 2Gpts, and noise is below 175μVrms. These parameters mean it can capture transient signals more accurately and present complex waveforms more clearly.
02 Why is 90GHz So Important?
The 90GHz bandwidth may just be a number to ordinary consumers, but it holds significant meaning for cutting-edge technology R&D.
In 6G communication R&D, testing of terahertz band signals must rely on ultra-high bandwidth oscilloscopes;800G/1.6T optical communication systems require testing equipment capable of analyzing ultra-high-speed modulated signals;Smart driving millimeter-wave radar testing also cannot do without high-performance oscilloscopes.
“Without suitable testing equipment, it’s like a nearsighted person trying to thread a needle.” An engineer involved in 6G research made a vivid analogy, “In the past, we often couldn’t accurately assess the real performance of prototypes due to insufficient testing equipment performance.”
The lag of testing instruments directly slows down the innovation pace of the entire industry.
03 From Following to Keeping Pace: The Advancement Path of Domestic High-End Instruments
The development of the Chinese oscilloscope industry is a typical story of catching up.
From the initial low-end digital oscilloscopes to mid-range products gradually replacing imports, and now achieving breakthroughs in the high-end market—domestic oscilloscopes have completed in twenty years what foreign companies took over half a century to achieve.
Liu Sang, CEO of Wanliyan, stated: “We have not only achieved performance breakthroughs but also made substantial progress in core chip autonomy. This means we are no longer constrained by others and can quickly iterate products based on market demand.”
Industrial chain security and autonomy are particularly important in the current international situation. The release of this oscilloscope marks that China has the strength to compete with international giants in the field of high-precision testing and measurement.
04 More Than Just “Domestic Substitution”
The significance of this ultra-high-speed oscilloscope goes far beyond “domestic substitution.”
In artificial intelligence, high-performance computing, and photonic chips, Chinese enterprises and research institutions finally have high-end testing options “at their doorstep.” This not only reduces R&D costs and shortens equipment waiting times but, more importantly, provides a solid guarantee for rapid iteration of innovative activities.
“We look forward to deep cooperation with domestic research teams to jointly define the next generation of testing instruments.” Liu Sang revealed that the company has already established partnerships with several leading research institutes to optimize product functions for specific application scenarios.
From “usable” to “easy to use,” from “following” to “keeping pace”—the advancement path of domestic high-end instruments is injecting new momentum into the entire hard technology industry chain.
In a chip design company in Nanshan, Shenzhen, the R&D team has already used the engineering prototype from Wanliyan. “Signal integrity testing efficiency has improved by 30%,” the chief scientist pointed to the clear eye diagram on the screen and said, “The most critical thing is that we can finally conduct cutting-edge interface technology research without any worries.”
Outside, the high-tech park in this city is brightly lit. In countless laboratories, the next generation of electronic information technology is quietly taking shape—and today, they finally have a clearer and more autonomous “Chinese eye.”
