China's high-end vector network analyzers have long been dominated by overseas manufacturers. Diancosi Instruments has more than 30 years of research and development experience in vector network analyzers.
China News Service, Beijing, October 27 (Reporter Sun Zifa) In the current turbulent era of artificial intelligence (AI), the wave of AI computing power has promoted the signal transmission rate of high-speed interconnection to evolve from 224G to 448G. High-speed cables, optical modules, optoelectronic chips, and high-speed PCBs (printed circuit boards) have become the focus of industry attention.
Industry experts say that signal transmission rates continue to increase, placing stringent requirements on link quality. Therefore, signal integrity testing has become an essential means for high-speed link design, debugging, and acceptance. However, China's high-end vector network analyzers have long been occupied by overseas manufacturers, and the independent breakthrough of domestic high-end test instruments has become a common proposition that the industry chain needs to overcome urgently.
As a "national team" in the field of test and measurement, China Electronics Technology's subsidiary Diankesi Instruments held an online new product launch conference with the theme of "In response to the needs of the times, born for high-speed intelligent connectivity" on the evening of October 26. It officially announced that it has achieved a major technological breakthrough in the field of microwave and millimeter wave testing, and released the latest results for AI high-speed interconnection testing needs, forming a complete testing chain from laboratory research and development verification to production line batch testing.

Among them, the 3674QB coaxial vector network analyzer is designed for 448G high-speed interconnection research and development testing, achieving integrated and continuous coverage of 10MHz-145GHz coaxial; the 3673 series vector network analyzer is built for the batch testing requirements of AI high-speed interconnection 224G production lines, with 8 models covering 100kHz-67GHz; a solution for industry-oriented PCB signal integrity testing was also released on site.
From series services for 224G production line batch testing, to supporting 448G cutting-edge research and development, to PCB signal testing solutions. The release of the latest achievements of Diankesi Instrument breaks the monopoly of foreign technology and helps users build testing capabilities from R&D verification to mass production through independent innovation of domestic high-end instruments.
It is reported that Diankesi Instrument has more than 30 years of research and development accumulation in vector network analyzers, and has formed four major product series: high-end, mid-range, economical, and modular. It is the main force for independent innovation of high-end electronic measuring instruments in China.
In recent years, Diancosi Instruments has continued to make breakthroughs in key technical fields such as microwaves and millimeter waves, optoelectronics, communications, basic testing and measurement, and quantum technology. It has a total of 550 authorized patents, and invention patents account for more than 90%. These breakthrough technologies not only break the decades-long foreign monopoly, but also play a key testing role in major national engineering projects such as lunar exploration, Beidou navigation, and deep space exploration.
Diancosi Instruments stated that the new vector network analyzer released this time has a coaxial frequency of up to 145GHz, providing solid testing support for independent innovation in China's new generation of information communications, radar, aerospace electronics and other strategic industries. In the future, it will continue to delve into the field of test and measurement, continuously consolidate the independent foundation of China's high-end electronic measuring instrument industry, and provide stable, accurate and efficient testing guarantees for AI high-speed interconnection and new generation communications industry.
