Aiming at improving the structure generalization and instrument interchange ability of the aerospace automatic test system,reducing inventory of the test system,and filling the blank of the LXI interface design of the aerospace automatic test system,the system architecture combining hardware and software is used. A design scheme of the LXI multi-functional inter-face card was put forward. The implementation methods of core technologies of IEEE1588 clock synchronization protocol and IVI driver was summed up in this paper. The design scheme will play an important role in application of LXI bus technology in the aerospace automatic testing system.
