Vxi Bus-based Data Acquisition Module

Virtual instruments (Vis) are the combination of the computers and traditional instruments. In 21st century, VI is one hotspot of research and application in the domain of measurement and control. During the development of virtual measuring technology, VXI is the perfect bus platform in market as well as in technology.In this paper, the goal is to make the VXI measurement system that is for school subject construction a readily used virtual instrument. First the paper introduces the composition of VXI measurement system both hardware and software. Second the paper introduces the AMC2320 8-channel parallel DAQ module, including hardware components, drive functions and means to develop application programs with them, the specifications such as precision. At last, the paper describes the digital oscilloscope and signal analyzer which developed with the DAQ module in details. They can analyze the received data from the DAQ, then display the input signals and the analyzed results in the soft panels.
