N4877A 时钟数据恢复具有 50 Mb/s 到 32 Gb/s 的工作速率。广泛的数据速率范围可测试新兴标准,例如 100GbE 和 FCx32,同时涵盖现有的低速标准。16G 选件支持高达 16.5 Gb/s 的速率,适用于 FCx16 和各种计算机标准,例如 USB 3.0、SATA、SAS 和 PCIe,包括 PCIe gen4。
恢复时钟或清除时钟
无法接入适当的被测件(DUT)时钟信号时,N4877A 提供用于 BERT 或采样示波器的必要时钟信号。如果时钟不可用或作为现有时钟(具有太多固有抖动)的清除 PLL 使用,N4877A 可从数据流中恢复数据,以执行精确的测量。
简化高速器件的接收机测试流程 N4877A 时钟数据恢复和 1:2 解多路复用器是 N4876A 2:1 多路复用器的对应产品,而且是对数据速率为 12.5 Gb/s 到 28.4 Gb/s 的 Keysight J-BERT 和 ParBERT 接收机测试解决方案的有益补充。
软件控制的热插拔解多路复用器输出、抖动容限测试模式和连接电缆套件专为 J-BERT N4903B 而设计,以简化接收机测试流程。
测量无时钟器件的实际性能
低固有抖动、可调谐的环路带宽、可选峰值和高灵敏度能够进行精确的发射机测量。N4877A 的辅助时钟输出提供小于 100 fs rms 的超低固有抖动,是配有精密时基的采样示波器的理想对应产品。
轻松控制所有设置
通过后面板 USB 连接和在 Windows® PC 上运行的独立用户界面,您可以控制 N4877A 的所有设置。
