%X The virtual instrument is a new-style instrument based on computer as hardware flat roof. In order to de- sign current virtual instrument with PC's hardware resource,PCI Bus and the interface chip are studied, the method of designing Add-In card is set up base on PCI bus, and the Add-In card of multi-wave signal generator is designed. Experimentation result show:the design method makes use of PCI bus' high speed features, DDS is realized by soft- ware. The signal generator can produce sin, triangle, square, noise, frequency sweep and others complex waves. The virtual multi-wave signal generator can be used to choose wave and to adjust its parameters conveniently and accurate- ly. It has rather strong current.
