| Abstract: | Adopting Virtual Instrument idea, this paper presents the design of a high data acquisition system with USB interface, which maximum acquisition frequency is 100MHz, implements the computer intelligent controls of collection frequency, trigger condi- tion, etc. And based on the design kernel by CPLD, expounds the logical control plan of high data acquisition and storage in detail, also expatiate upon the implementation of the USB bus interface. By dint of computer, the system can provide Virtual Instrument' s function of bus interface oriented. |
