特点

利用 M8040A 获得准确且可重复的结果

M8040A 高性能 BERT 的跳变时间更短，固有抖动更低，能够提供数据速率高达 64 GBaud 的纯净 NRZ 和 PAM4 信号。 M8040A 的远程前端和 1.85 mm 短电缆使测试点可以尽量接近被测器件，最大限度降低有损通道造成的信号衰减。

  • 2 至 64 GBaud 的 PAM4 信号数据速率
  • 真正的实时 PAM4 误码检测能力，数据速率高达 58 GBaud
  • 内置去加重、分析仪均衡和时钟恢复功能
  • 整合和校准过的抖动注入：RJ、PJ1、PJ2、SJ、BUJ 和时钟/2 抖动
  • 每个模块有两个码型发生器通道，用于仿真干扰源通道
  • 8/16/32/64 GT/s PCI Express® 交互式链路训练和 SKP OS 过滤
  • 可以通过算法生成 PRBS、QPRBS 码型，也可以使用保存在存储器中的码型或是通过码型序列发生器生成的码型
  • 用于 PAM4、Gray 编码、FEC 编码、预编码器和误码分布分析
  • 所有选件和模块均可升级
  • 提供真正的误码分析功能，能够提供准确且可重复的测量结果，从而优化您的器件的性能裕量

目标应用

M8040A 专为研发和测试工程师设计，帮助他们表征芯片、器件、收发信机模块和子组件、电路板以及系统。这些被测器件和系统配有串行 I/O 端口，数据速率高达 32 GBaud 和 64 GBaud，主要在服务器、计算、数据中心和通信行业中使用。

许多流行的互连标准使用了 PAM4 和 NRZ 数据格式。M8040A 可对这些标准进行接收机（输入）测试，如下所示：PCIe 6.0/5.0/4.0、TBT3、400 GbE、50/100/200/400/800 GbE、OIF CEI-56G 和 CEI-112G、64G/112G 光纤通道、Infiniband-HDR，以及芯片间、芯片与模块、背板、中继器和有源光缆的专有接口。

M8040A 64 GBaud BERT 的码型发生器可提供纯净的 32 和 26.5625 GBaud PAM4 输出信号。

Accelerating from 100GE to 400GE in the Data Center Advanced Modulation and Coding Challenges

Accelerating from 100GE to 400GE in the Data Center Advanced Modulation and Coding Challenges

The move from 100GE to 400GE in the data center is revolutionary, not evolutionary. Optical transceivers will need to use advanced signal modulation and coding to reach 400GE speeds. These techniques create new test challenges for transceiver manufacturers.
