Abstract In order to achieve the miniaturization of electronic servo system, a data acquisition system, based on FPGA(Field-Programmable Gate Array) was developed. Broadband, high-speed, low-power microchips were introduced into circuits to process the weak fluorescence spectrum signal, then the FPGA high-speed photon counting method was applied to signal acquisition. It can replace the traditional computer software LABVIEW combined with commercial instrument data acquisition system. So efficient data acquisition were realized in physical ion microwave frequency standard system.
