摘要
伴随着电子科学技术的发展,示波器的使用需求也日益增加,文中旨在通过FPGA架构实现数字示波器,以更为经济的方式满足教育机构和实验室的要求。研究表明,非专业示波器可以用低成本的、教育用的FPGA来实现。由FPGA控制高精度ADC通过等效采样和实时采样两种方式,用FPGA完成信号采集到处理显示的全过程,集成度高。示波器系统有着自动频率控制采样和自动增益控制模拟通道的信号调理功能,可以方便地对信号进行测量(测频、测幅)、绘制波形与频谱图等功能。
With the development of electronic science and technology,the use of oscilloscopes is also increasing.In this study,the purpose is to realize digital oscilloscopes through FPGA architecture,to meet the requirements of educational institutions and laboratories in a more economic way.The research shows that the non professional oscilloscope can be realized with low-cost and educational FPGA.FPGA is used to control high-precision ADC,and the whole process of signal acquisition,processing and display is completed with FPGA through equivalent sampling and real-time sampling.The oscilloscope system has the functions of automatic frequency control sampling and automatic gain control analog channel signal conditioning,which can easily measure the signal(the frequency and amplitude),draw the waveform and spectrum diagram and other functions.
