In the laboratory, the waveform on the silver device is steadily fluctuating, and Chinese engineers are clenching their fists—this moment rewrites the history of high-end electronic measurement instruments in China.
On October 15, 2025, at the Bay Area Semiconductor Expo in Shenzhen, China’s self-developed 90GHz real-time oscilloscope was officially unveiled. This device has a bandwidth exceeding 90GHz, reaching international top levels, establishing a “Chinese standard” for measuring ultra-high-speed signals in the global electronic communication industry.
Its emergence marks a critical breakthrough for China in the field of high-end electronic measurement instruments, tearing open a gap in the long-standing technological blockade from abroad.
The development difficulty of this 90GHz oscilloscope is no less than that of the lithography machines used in chip manufacturing.
To put it simply, a real-time oscilloscope is the “high-precision ruler” in the field of electronics—whether it is communication signals, computer data, or electrical signals in aerospace equipment, it is essential for capturing, measuring, and analyzing; without it, many industries cannot function.
Previously, the high-end oscilloscope market in China was completely monopolized by foreign companies; we had to listen to what they sold and at what price. Now, it is different. Our domestically produced 90GHz device can already match international top levels, becoming a “standard ruler” usable by the global electronic communication industry.
The high-end electronic measurement instrument industry has been monopolized by foreign companies for too many years. For China, this not only constrains our industrial development but also hides significant information security risks.
Just think, if the measurement tools in critical fields rely entirely on imports, what if one day the supply is cut off, or if there are “backdoors” hidden in the equipment? Our research and production would be directly put in a passive position.
Therefore, having core technologies that are self-controllable has long been a national strategy. The successful development of this 90GHz real-time oscilloscope is a tangible “breakthrough”—from now on, we no longer have to look at others’ faces in the high-end measurement field.
The applications of this oscilloscope are vast, and many industries are waiting for it to “save the day.”
In the semiconductor industry, chip design, testing, and validation all rely on high-precision measurements. Now, with the domestically produced 90GHz oscilloscope, we can keep pace with the rapid development of China’s semiconductor industry; in the communication field, as 5G continues to proliferate and 6G begins development, the measurement requirements for high-frequency signals are increasing, and this device can provide a solid “scaffold” for new technology development; more critically, in sensitive areas such as aerospace and national defense, having self-controllable high-end measurement instruments allows us to conduct research and projects more safely and confidently, without fear of being “choked” by others.
This technological breakthrough is not just the achievement of a single company or team, but a reflection of the overall enhancement of China’s innovation capability—enterprises, universities, and research institutions have come together to tackle this “hard nut.”
In fact, in recent years, China has continuously made breakthroughs in high-end manufacturing: the “Chinese Sky Eye” FAST has discovered 1,152 pulsars, and the operational task volume of the third-generation submersible accounts for more than half of the global total. Coupled with this 90GHz oscilloscope, innovation has long been the “core engine” of China’s high-quality development.
Of course, this is also inseparable from policy support. Whether it is the construction of charging facilities promoted by the National Development and Reform Commission or the central bank’s reverse repurchase operations, all are creating a favorable environment for technological innovation, allowing research and development teams to focus on breakthroughs.
Now, the Chinese 90GHz real-time oscilloscope has become a “universal ruler” in the global communication, semiconductor, and aerospace fields, but this is just the starting point—what is more important next is to transform the achievements in the laboratory into real industrial advantages, and even exceed others in the speed of technological iteration, truly shifting from “running alongside” to “leading the way.”
From relying on imports to producing a globally applicable “Chinese standard,” the breakthrough in high-end measurement instruments is like a microcosm: Chinese manufacturing is shifting from “competing in scale” to “improving quality.” When “Chinese standards” begin to be recognized by the world, which field do you think will be the next to have its rules rewritten by us?
