The concept of a virtual instrument and its data acquisition system are represented in this paper. Through the technical composition of hardware software, the signal acquisition and processing of various kinds of simulation parameters from multiple channels are realized. Making full use of advantages of the virtual instrument and adopting modular programming design method, the applicable softwares which are independent of equipment and interface types are developed. This system can satisfy the multiple requirements of test tasks.
