Teledyne LeCroy 示波器的USB4bus DME(解码、测量/图形和眼图)选项能实现在 USB4.0 物理层波形上标注链路层解码信息。 这提供了在示波器上查看协议流量的能力,并能验证链路是否连接与传输是否正常。 它还有助于调试在本质上不仅仅是模拟或数字的问题,例如互操作性问题、不确定的错误原因以及用协议分析仪无法显现的物理层问题。
Simply click on the packet of interest in the protocol table to create a zoom window of the waveform with color coded overlay showing the packet type, command type, and message details.
The TF-USB-C-HS probing coupon enables the industries only oscilloscope that triggers on USB4-SB signals and simultaneously captures high-speed data up to 20 Gb/s on an active link.
Use TF-USC-C-HS (USB4 High-speed and sideband test Coupon Fixture), DH Series differential probes, USB4bus DME, and USB4-TDMP software to debug PHY link layer training failures on USB4 and Thunderbolt routers, re-timers, and active cables.
USB4 DME (Decode, Measure/Graph, and Eye Diagram) software provides eye diagram measurements by recovering the clock on decoded symbols. Used to evaluate high-speed signal quality during link training as the transmitter sends SLOS (Symbol Lock Ordered Sets) to the receiver during link training.
只需单击协议表中感兴趣的数据包,即可创建波形的缩放窗口,其中彩色编码覆盖层显示数据包类型、命令类型和消息详细信息。
TF-USB-C-HS 测试夹具实现了业界唯一的示波器触发 USB4-SB 信号并同时捕获有效链路上高达 20 Gb/s 的高速数据。
使用 TF-USC-C-HS (USB4 高速和边带测试夹具 )、DH 系列差分探头、USB4bus DME 和 USB4-SB-TDMP 软件对 PHY 链路层训练失败进行调试,主要针对 USB4 Thunderbolt 路由器、重定时器与有源电缆。
USB4bus DME(解码、测量/图形和眼图)软件通过恢复解码符号上的时钟来实现眼图测量,用于评估发射端在链路训练期间向接收端发送 SLOS(符号锁定有序集)时的高速信号质量。
