Ping Li · Automation and Instrumentation · 2008
This paper introduce the chief techniques and design principles of an virtual digital storage oscilloscope based on high-speed data acquisition techniques,which has two working modes:oscilloscope and data acquisition.The hardware instrument consists of preprocessing circuit,AD converter on board memories,high speed clock generator and control circuit integrated in FPGA,comected with PC board through PXI CAN.the software is developed by Labwindows/CVI produced by NI corpration.The design uses 128MB synchronous dynamic storage,which is of character of large memories,low cost,high speed,It can be comprehensively applied in occasion with high-speed,large storage data acquisition,and oscilloscope.
