Virtual oscilloscope based on VXIbus

This paper introduces how to design the software of virtual oscilloscope based on VXI devices. This oscilloscope has multi functions, multi channels and high resolution. The test data can be stored and shared through network. And the oscilloscope supports remote control. The emphasis is put on the virtual instrument software structure analysis, the database application in virtual instrument software and on how to use plug ins to enhance the efficiency and reliability of virtual instruments.
