摘　　要：误码测试设备采用工控计算机作为设计平台,WINDOWS 2000作为操作系统进行软硬件设计。采用专用误码测试芯片发送/接收测试码,使用大规模集成电路及可编程门阵列FPGA,接口电路包括专用接口和通用接口,其通用数据接口采用多协议接口芯片,能够支持RS422/RS232/V.35等V系列建议接口。采用友好的WINDOWS操作界面,有几十种测试码型,接口类型丰富,不仅能实时显示误码数、误码率和告警等测试结果,还可自动生成测试日志,方便用户对测试结果的输出及分析。The design of the software and hardware of the bit error rate tester is performed on the industry control computer and in WINDOWS 2000.The special chip sends or receives the testing code. The logic circuit is designed in FPGA. The interface circuit includes special and universal interfaces. The universal data interface adopts multipretocol interface chip, supporting such interfaces as RS232, RS449, EIA530, V. 35, V. 36, X. 21 etc.. It adopts friendly operating windows, has many kinds of test codes and test interfaces. It can not only display the real-time bit error number and bit error rate and alarms, but also automatically generate test logs for users to output and analyze the test results.
