研发和测试工程师在表征串行接口时,可使用配有去加重选件的 M8061A 2:1 多路复用器,将 J-BERT M8020A 和 J-BERT N4903B 码型发生器的数据速率扩展至 32.0 Gb/s。M8061A 提供已校准的 4 分接去加重(可扩展至 8 分接)、内置干扰叠加和时钟/2 抖动注入,可获得最精确的接收机表征结果。M8061A 是一个 2 插槽 AXIe 模块,通过 USB 在 J-BERT M8020A 和 N4903B 用户界面上进行控制。
不少多千兆位串行接口使用发射机去加重,旨在补偿使用(在发射机和接收机端口之间)印刷电路板或电缆传输电信号时引起的信号质量下降。研发和测试工程师在实际条件和最坏情况下表征接收机端口时,需要使用码型发生器和可调的 4 分接去加重,以精确地仿真发射机去加重。M8061A 可与 J-BERT M8020A 结合使用,如下所示。 该设置显示了如何使用 M8061A 和 J-BERT N4903B 以高达 32 Gb/s 的速率进行发射机去加重仿真。对于速率高达 32Gb/s 的 BER 和抖动容限测量,必须使用 N4877A CDR 和去多路复用器。
最大程度地降低测试环境带来的影响是一项艰巨的任务,特别是在比特率超过 20 Gb/s 时。为了对电缆、测试夹具、适配器等引起的信号质量下降进行去嵌入,通常会使用去加重技术。M8061A 是唯一具备 8 分接去加重能力和 32 Gb/s 数据速率的仪器,能够精确地补偿信号质量下降。
