| Abstract: | This paper discusses the chief techniques and design principles of an digital storage oscillogragh based on FPGA,an apparatus including digital sorage oscillescope and digital mutimeter, which makes full use of high-speed data acquisition technology, uses FPGA as kernel controller, and completes transmission with PCI bus. The instrument consists of pre-process circuit, A/D converter, SDRAM, FPGA and PX1 chip. The test result indicates that the system works normally and the design is successful. |
