A New High-Speed Data Acquisition System

摘要

The lower hybrid current drive (LHCD) system plays an important role in the Experimental Advanced Superconducting Tokamak. A new data acquisition system is designed to meet the requirements of high-speed signal processing in LHCD. In this system, FPGA is used as the main logic unit and USB is used as the interface, at the same time, the system firmware program is complied. Experiments show that the system has a very good effect and also has potentially broad application in many fields such as bioengineering and transportation.
