Based on LabVIEW and CompactRIO platform, a test system is developed for High Power Microwave(HPM) source. The structure design and the implementation method of control system are described. The system uses different modules to realize process control, data processing, data acquisition and so on. With serial communication and optical fiber transmission technology, the safe reliable remote monitoring and data communication are both implemented. The system is verified through the experiments. It is stable and efficient, which establishes the technical basis for the further development of HPM source technology verification.
