Title Design of virtual signal generator and test system based on VI

Abstract Virtual instrument technology has a very wide range of applications in the field of electronic measurement, and it is a fundamental technology of computer aided testing。 This topic requires the design of a virtual instrument, with a virtual signal generator and oscilloscope function, so as to establish a complete set of signal generation and testing system。 At first, this paper analyzes the background, concept and structure of the virtual instrument, and summarizes the software platform LabVIEW which is used in this project, to understand the use of the function in this design。 Then according to the goal of the project and the function that LabVIEW provide, finishing the whole program design ideas, in order to accomplish the specific design of each module of the program, including program on the front panel, adjustable electrical parameters of the waveform generation system, dual-channel oscilloscope, range adjustment function, and the cursor display function。 Finally shows the debugging results of the program, in order to illustrate that the program has basically completed the intended target。
