This paper studied a testing system which based on PXI bus. Based on the problem that traditional testing method is not reliable and maintainable, a new testing scheme of using the rapid and steady board is presented. Based on the problem that the traditional testing method is bad in durability and visibility, a testing method of using the DAQ cards of NI is presented. The automatic test system architecture, composition and principle are analyzed.And on this basis,according to the system hardware design and universal test interface,integrated software development and other areas were illustrated and explained in details,based on the actual project design demand.
