Abstract :
In order to compare and analyze signals, it is usually necessary to acquire simultaneously and analyze multi-channel signals in practice and study, such as condition monitoring, fault diagnosis, automatic control, and so on. A high-speed four-channel simultaneous data acquisition system, based on DSP, USB 2.0 and CPLD, has been developed. This system takes full advantages of the ability of high-speed processing and analyzing of DSP, and of high-speed communication of USB 2.0. These make the system has an excellent integrative performance, meets the demands of the high-speed multi-channel simultaneous-acquisition. The system is smart, portable and flexible. A virtual dynamic signal analyzer based on this system has been developed
