摘　　要：提出了一种SDH网络分析仪指针调整测试模块的设计方案,该方案严格按照ITU-T G.707和ITU-T G.783的建议对AU4/AU3与TU2/TU12/TU11指针进行调整。通过编写RTL代码与仿真,利用FPGA器件实现并与SDH测试仪、通信设备对接验证,已广泛应用于SDH仪表和设备产品的研发。A module design scheme of pointer adjustment for SDH analyzer is presented. According to the rec- ommendation of ITU-TG.707, ITU-TG.783, it is designed to adjust the pointer of AU3/AU4 and TU2/TU12/ TU11. The RTL code of design has been coded in Verilog and simulated with NC-VERILOG software, cer- tificated by FPGA hardware platform, SDH analyzer and SDH equipment. It has been widely used in research and development of SDH measurement instrument and equipment and so on.
