Abstract :
This paper discusses the chief techniques and design principles of a digital storage oscilloscope card based on VHDL, which takes full advantage of high-speed data acquisition technology. FPGA is adopted as the kernel controller, and VHDL design method is utilized to achieve the global logic control. The instrument consists of pre-process circuit, acquisition circuit and FPGA and so on. The test result indicates that the system works stably and the design is successful.
