Recently, the National Key Research and Development Program project "Research and Application of Precision Wideband Lock-In Amplifiers," led by Professor Wang Zixin from Sun Yat-sen University as the project head and chief technical advisor for the Sine Scientific Instruments team, was approved. This project aims to develop precision lock-in amplifiers with a bandwidth exceeding 100 MHz and to research weak signal decoupling technology in complex electromagnetic environments, achieving high-bandwidth and high-precision detection capabilities.

Sine Scientific Instruments has a team of returnees with extensive experience in integrated circuit design, electromagnetic compatibility analysis, and digital signal processing. The team has been conducting research related to weak signal detection in collaboration with the Department of Microelectronics, Department of Physics, and the State Key Laboratory of Optoelectronic Materials and Technology at Sun Yat-sen University.

Sine Scientific Instruments is a national high-tech enterprise focused on weak signal detection technology for nearly twenty years, holding a series of core intellectual property rights in this field. The company offers a range of lock-in amplifier products covering various frequency bands, with performance parameters that comprehensively match international counterparts. These products have been widely applied in hundreds of research institutions and enterprises both domestically and internationally, receiving unanimous praise from clients worldwide.
