针对冲击波超压引线测试法中存在的问题,设计了一套基于FPGA的存储测试系统。系统选择ICP传感器并针对此传感器设计了相应的恒流源电路、滤波电路。装置采用FPGA芯片作为主控芯片,集采集、触发、存储、传输等功能于一体。使用该系统对冲击波信号进行测试,得到完整的冲击波波形。 Aiming at the problems existing in the test method of shock wave overvoltage lead, a FPGA-based storage test system is designed. The system chooses ICP sensor and designs the corresponding constant current source circuit and filter circuit for this sensor. The device adopts FPGA chip as the master chip, which integrates the functions of acquisition, trigger, storage and transmission. Use this system to test the shock wave signal to get the complete shock waveform.
