Research&Development Of Data Acquisition Module

Virtual instruments (VIs) technology are the combination of the computer technology,the modern test-measurement technology and the tradional instrume- nts.It is a milestone of instrument development.During the development of virtual measuring technology. VXI platform is preponderant in market as well as in technology. The virtual instrument,Labview and the VXI bus technology are introduced in brief at first. After the hardware structure and function of VXI-MIO-64XE-10 module are introduced,this paper illustrates how to program the VXI-MIO-64XE-10 module with Labview and how to test the function of the moduleThe design of the virtual signal generator based on the output channels is introduced.This paper emphasize on the virtual frequency spectrum analyzer based on the input channels of the module.The design of the main program and the function modules of the virtual frequency spectrum analyzer are illustrated in detail.Several examples are given at the end of this paper to test the function of the virtual frequency spectrum analyzer. spectrum analysis...
