Based on a comprehensive analysis of the testing requirements of a transponder and related COTS products, a design idea and scheme for developing a transponder testing system are proposed. PC-104 is used as the display control and data processing center of the system. By expanding the HT-7484 Multi-functional interface board, the hardware circuit of the system is designed. According to the functional requirements of the human-machine interface of the system, a man-machine interface is designed, a software test procedure is compiled, the system integration and debugging are completed, and the function of an answering machine The test results show that the transmitting power of the transponder is normal and the response probability meets the performance requirements. The device has the advantages of high reliability, good stability and easy to use Features.
