| Abstract: | A MA module of matrix switch and its interface and driver circuits are introduced.FPGA is used to finish the timing of M/MA interface and the logic control of relay switch,while HL and LL d-layer software architecture are used to implement the drive program for MA module.The test result shows that the module can work stably in four modes,not only switch continuously and rapidly but store the frequency of switching action,which ensures the signal can be switched reliably in real time. |

| Keywords: | MA module matrix switch rapidly switching counter of switch action |
