高精度数据采集模块设计及CCSLink性能测试

Design and performance test based on CCSLink of highly accuracy data acquisition module

从器件选择和电路设计两方面,设计了无线电导航接收机的高速数据采集模块,并利用集成在MATLAB中的CCSLink工具和作者开发的接收机板上的FPGA和DSP,设计了基于FPGA和DSP的测试软件,对ADC进行了可编程、数字化的性能测试。

The project design and technical specifications of radio receivers are largely depended on the data acquisition module, which is usually as the input part of digital signal processing in radio receivers. In the same time, the reasonable test technology is critically important for evaluating the performance of ADC accurately. The highly accuracy data acquisition module was designed in ADC selection and circuit design. The programmable and digital performance test software was designed for ADC by CCSLink integrated in MATLAB and FPGA ＆ DSP in the developed circuit board.
