摘　　要：提出一个经过优化的数据采集方法,辅以FPGA(Field-Programmable Gate Array)主控制器和必备的外围电路完成了基于FPGA的数字存储示波器的设计。系统最大限度地利用了FPGA的高速数字信号处理能力以及众多硬核和软核内嵌的特性,降低了成本和开发难度。将数字存储示波器及信号源的基本原理和经过优化的数据采集方法相结合,分别在模拟信号预处理、数据多方位存储、触发方式、等精度测频等环节进行创新性优化,经测试,系统性能良好,各项指标均能较好满足要求,为新型简易数字存储示波器的发展提出了新思路。An optimized method of data collection is proposed to complete the digital storage oscilloscope, which is supported by FPGA as its controller platform and the necessary peripheral circuits. The system uses FPGA high-speed digital signal processing and embedded of many modular circuits and soft-core characteristics, reducing the cost and difficulty of development. The combination of the basic principles of digital storage oscilloscope and signal source with new data acquisition and processing method and the optimization at analog signal preprocessing, data multi-faceted storage, trigger mode, and equal precision frequency measurement . After testing, the system has excellent performance,and all this provides new ideas for the development of new simple digital storage oscilloscope.
