【Abstract】 This paper retrospects the development of virtual instrument in these years,and introduces the concepts of integrated measuring,distributed measuring,distributed virtual instrument based on the analysis of the characteristics in every phase.A sort of system is proposed which combines with the advantages of integrated measuring and distributed measuring,it is applied to enable new measurement patterns leveraging efficiency,and a self-made distributed virtual oscillograph is described to demonstrate the potential and the benefits of the proposed approach.Finally,the trend of virtual instrument system on the basis of network and information is predicted.更多还原
