介绍基于USB2.0协议、最多可四路同步采样的高速同步数据采集系统。其单通道采样速度620ksps,四通道同时采样速度可达180ksps。USB接口控制及通信芯片采用Cypress公司FX2系列中的CY7C68013,通过对其可编程接口控制逻辑的合理设计和芯片内部FIFO的有效运用,实现了数据的高速连续采样。
Introduce high-speed synchronous data acquisition system based on USB2.0 protocol, up to four simultaneous sampling. Its single-channel sampling rate of 620ksps, four-channel simultaneous sampling rate of up to 180ksps. The USB interface control and communication chip adopts CY7C68013 in Cypress FX2 series. Through the reasonable design of its programmable interface control logic and the efficient use of FIFO in the chip, high-speed continuous sampling of the data is realized.
