Abstract: A large amount of data acquisition，storage and analysis should be carried out during the research for some type of missile.Constructing a test system consisting of VI can greatly simplify the design，reduce the volume and weight，shorten the research interval and acquire a good flexibility.This paper introduces a general-purpose test platform for missile based on PXI bus and NI Series cards.It can acquire and test the data from analog，digital，bus and image channels and can communicate with the tested products.The test system has already been put into operation，which has features of appropriate design，reliable performance，accurate testing，convenient operation and satisfied results.
