摘　　要：为解决计算机测试系统中频率测试的高精度要求,提出了一种基于FPGA技术的多通道等精度测频法。设计了频率测试系统,该系统实现了在5kHz～500kHz频率范围内测量分辨率为1Hz。In order that the paper was solved high-precision frequency measurement on the computer measurement system, there was proposed a method which one of the multi-channel and equal-precision frequency measurement based on the FPGA （Field Programmable Gate Array）. Design of the frequency-measurement system. Frequency measurement resolution is achieved 1 Hz at 5 kHz-500 kHz.
