摘　　要：为实现汞离子微波频标电子伺服系统的小型化，设计了一种基于FPGA的汞离子频标数据采集系统。采用宽带、高速、低功耗的微芯片电路模块对离子跃迁谱线的微弱荧光信号进行放大、整形、降噪处理；利用FPGA高速光子计数法对信号进行采集。取代了传统的计算机软件LABVIEW与商用仪器结合的数据采集系统，实现了对离子微波频标物理系统中微弱荧光信号的有效采集。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.
