安立Anritsu MP2110A采样示波器操作流程

Anritsu MP2110A是款集BERT(误码率测试仪)和采样示波器于一体的高性能一体化测试仪器,主要用于10G至1.6T光模块的制造与研发测试,以下就是Anritsu MP2110A的操作流程详解。Anritsu MP2110A操作流程基本连接与初始化物理连接:根据被测设备(DUT)类型,使用对应光/电接口连接MP2110A与DUT。开机自检:仪器启动后自动加载默认配置,建议首次使用前执行校准(Setup → Utilities → Calibration)选择模式:通过前面板或软件界面进入BERT模式或采样示波器模式。TDECQ测量流程(适用于PAM4信号)这是MP2110A的核心应用之一,尤其用于200G/400G/800G光模块测试 。1.Signal Type设置设置为PAM4。2.Sampling Mode设置选择 Coherent Eye(相干眼图模式)。3.Test Pattern配置推荐使用长PRBS码型:PRBS13(8191 symbols)PRBS15(32767 symbols)SSPRQ(65535 symbols)注意:TDECQ 测量时不可选择 Variable 长度。4.Accumulation 设置Accumulation Type:LimitedLimit Type:Pattern(设定采集的pattern数目)。5.Amplitude/OE 设置设置输入连接器(Input Connector)与波长(Wavelength)。选择数字滤波器(名称含[D]),仅在Coherent Eye + Pattern模式下可用 6.Trigger设置(如无CRU)若使用外部触发:Divide Ratio Detect:OffDivide Ratio根据信号速率选择(如26Gbaud选1/2,1/4,1/8,1/16)7.自动设置时钟速率点击Auto Scale或Acquire Clock Rate自动锁定速率 。8.开始测量进入Measure→Equalizer,点击Auto Scale→Calculate→Sampling Run开始TDECQ测量。常规眼图与BER测量流程设置比特率:根据DUT速率(如25.78125G、53.125G等)配置BERT速率。选择测试图案:PRBS7/9/13/15或自定义。同步Tx/Rx测量:MP2110A支持最多4通道BERT+ 4通道采样示波器同时工作。只需设置一个通道,其余通道可自动同步。启动测量:点击Acquire或Start,结果可同时显示BER和眼图。
