The most important feature of LabVIEW programming is a fool, in order to engineer from the tedious programming freed, LabVIEW implements modular test instruments, making the test more flexible configuration, the design developed by National Instruments virtual instrumentation based on virtual signal generator, and traditional instruments compared to the price compared to cheap, simple, practical wide range of simple design and so on. The actual needs of the user can use the LabVIEW (a graphical editing language) design features of the virtual instrument. Can also be released through the network, then the client can remotely view and control a virtual signal generator. The main work is to combine the virtual instrument technology, arbitrary waveform signal generator of research and design. First, the paper introduces the basic theory of virtual instrument technology, including virtual instrument concept, composition, classification, and virtual instruments compared with traditional instruments .On this basis, virtual instrument system software architecture, describes a simple instrument drivers, VISA and other related technologies. Secondly, the paper was arbitrary wa
