Automatic test and control system is the desired system for the test of massive electronic equipments. In this paper, an automatic test and control system for a certain type of radar seeker is proposed, based on the virtual instrument technology. The system architecture on the basis of the Compact Peripheral Component Interconnect (CPCI) platform is introduced, and the design and implementation of the special-purpose boards and supporting software are discussed. After the system calibration, system testing was performed. The testing results prove that this system with high efficiency and accuracy is suitable for the test of the radar seeker and other similar products.
