We designed and implemented a signal generator that can simulate the output of the NaI(Tl)/CsI(Na)detectors'pre-amplifier onboard the Hard X-ray Modulation Telescope(HXMT).Using the development of the FPGA(Field Programmable Gate Array)with VHDL language and adding a random constituent,we have finally produced the double exponential random pulse signal generator.The statistical distribution of the signal amplitude is programmable.The occurrence time intervals of the adjacent signals contain negative exponential distribution statistically. 展开更多
