Chinese Academy of Sciences 4GHz Bandwidth Real-Time Digital FFT Spectrum Analyzer System Received Acceptance
[China Instrument Network Instrument R&D] Recently, the test and acceptance of the “4 GHz Bandwidth Real-time Digital FFT Spectrum Analyzer System†project of the Chinese Academy of Sciences Scientific Research Instrument and Equipment Development Project undertaken by the Nanjing Purple Mountain Observatory was held in Nanjing, Jiangsu Province. The responsible personnel of the Bureau of Condition Protection and Finance of the Chinese Academy of Sciences, the technical testing expert group, the acceptance expert group, and the project team members attended the test acceptance meeting.

The real-time spectrum analyzer can seamlessly perform FFT calculation and spectrum triggering within the real-time analysis bandwidth, which is very favorable for the capture and analysis of transient signals, spectrum monitoring, radar system design, frequency hopping radio testing, oscillator development, etc. The field has a wide range of applications.
The newly developed spectrum analyzer system uses a 10 GSPS single-core ADC to directly sample a 5 GHz bandwidth signal and implements 64 k channel real-time digital FFT processing. The expert team highly appraised the project development work and agreed that the project team completed all the tasks specified in the project implementation plan and achieved the project's expected goals.
The expert group believes that the developed system technology level is at the leading position in China and has reached the international advanced level. The system can directly meet the needs of the National Antarctic Observatory's 5-meter terahertz telescope, which is a major national science and technology infrastructure, and has important application value for various types of radio astronomical observations and other spectrum measurement fields.
