A high time resolution multi-channel pulse generator based on FPGA has been placed, which is designed for Four-Channel framing camera. The system which provides for four independent output channels Combined with a high voltage shutter circuit to regulate the exposure and delay time of the Four-Channel framing camera. It used the high-speed counter within the FPGA to realize precision regulation, fiber communication to realize long-distance control and high-speed high-voltage interface to improve the output drive capability. The minimum time scale of the system is 4 nanoseconds, the range of the output pulse is 7.5 voltages, and the transmission distance is longer than 10 kilometers.
