| Abstract: | The technique of high speed data acquisition, which iscomprehensively applied in advanced measuring instrumentation, is a key part of wide band analog signal data acquisition. The article analyzes in detail the principle and the implementation of a 250 MSPS acquisition system. In this system, the scheme of multi channel synthesis is applied to implement high speed AD conversion with lower speed AD conversion, which effectively decreases the difficulty of the system implementation and enhances the system reliability. Moreover, the interface method of direct memory map is adopted to implement the data sharing between high speed data acquisition card and computer, realizing high speed data transmission from AD card to computer. Finally, the article analyzes the system performance theoretically. |
