摘　　要：误码仪在通讯中起着至关重要的作用,是衡量一个通讯系统优劣的工具,传统的误码仪价格昂贵,操作复杂,不便于携带.以FPGA及其外围电路为硬件部分,在Quartus软件平台上,推出了基于测量SDH中E1信号映射解映射的误码仪,并根据实验的验证,符合工业化测量的需要.The Bit Error Rate Tester plays a vital role in communication system. It is the tool that weighs communications system advantages or disadvantages. The traditional bit error rate tester is expensive, complicated in operation and inconvenient in carrying. In this paper takes FPGA and peripheral circuits as the hardware part and based on the Quartus software.Designed BER testing principle based on El signal in SDH communication system.In the next experiments verificated that it’s conformed to the industrialized measurement standard.
