In order to meet the requirements of autonomous control and portability of test equipment for a certain series of weapon equipment, the domestic multi-interface portable test equipment is designed. The equipment adopts domestic processor and domestic operating system, combined with the actual needs of field test applications, to provide excitation power supply, excitation signal and electrical performance test for the equipment under test; based on the design of Loongson 2K1000J CPU, it expands a variety of functional interfaces through FPGA, and adopts the national production of software and hardware. The practical application results show that the equipment reduces the types of other field test equipment, is easy to carry and operate, improves the convenience of equipment maintenance, and has a high level of autonomy and controllability.
