Shenzhen: China’s homegrown 90GHz ultra-high-speed real-time oscilloscope was officially unveiled on Wednesday, marking a milestone in the global electronic communications sector. The breakthrough was announced at the WESEMiBAY Semiconductor Ecosystem Expo 2025, held from Wednesday to Friday in China’s southern metropolis of Shenzhen.

According to Namibia Press Agency, an oscilloscope is a key upstream equipment in science and industry, widely used in product research and development, testing, and manufacturing. It transforms invisible electrical signals into visible waveforms, serving as the “eyes” and “reference” for engineers and scientists.

Liu Sang, CEO of Shenzhen Longsight Technologies Co., Ltd, one of the developers, highlighted that the achievement requires sustained integrated innovation, featuring cross-disciplinary fusion and systemic optimization across foundational materials, precision manufacturing, core chips, and algorithms. The oscilloscope has already been tested and applied by several re
search institutions and enterprises, including Huawei.

Spanning more than 60,000 square meters, the expo brings together over 600 exhibitors and featured high-end forums, providing innovative companies with a platform aligned with global standards.
