DisplayPort DP-AUX 解码、测量/绘图和物理层 (TDMP) 将您的示波器转变为 DisplayPort AUX 分析仪;提供透明颜色编码解码叠加、协议表和搜索功能、具有自动测量和绘图工具的测量/绘图功能以及用于物理层信号评估、调试和眼图创建的 DP-AUX EYE 标准特定功能。
Triggering of the oscilloscope on DP-AUX channel reads/writes provides unique PHY-logic layer debugging capabilities not found in other oscilloscopes or other AUX analyzers.
A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand your serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show you just the right amount of information.
Simply click on the DP-AUX packet of interest in the protocol table to create a zoom window of the waveform with color coded overlay showing the packet type, command, AUX register address, and message details.
DisplayPort DP-AUX TDMP can be used as standalone for Standard DP connector or eDP designs; or along with USB-PD TDMP to analyze timing between the DP-AUX (SBU lines) and USB-PD (CC lines) in a DisplayPort over USB-C design. Msg-Msg timing measurements can be used to debug system interoperability issues caused by improper timing between USB-PD Alt Mode transactions and DisplayPort AUX link training.
The DisplayPort 2.1 PHY CTS requires DP-AUX EYE diagram measurements on the AUX transmitters on both Sources and Sinks while transmitting 16 SYNC pulses. QPHY-DP2-SOURCE automates the use of DPAUX TDMP to decodes the DP-AUX data, make the required EYE diagram mask and measurements with Pass/Fail compliance results.
Use TF-USB-C-HS or TF-USB-C SB test coupon fixtures and probing solutions provide the best solution for DisplayPort Source/Sink device system integration. For instance, debugging LTTPR timing failures between AUX and Main Link or AUX and ‘Alt Mode’ Power Delivery messages.
在 DP-AUX 通道读/写上触发示波器提供了其他示波器或其他 AUX 分析仪所没有的独特的 PHY 逻辑层调试功能。
透明覆盖层对每个协议的特定部分和整个消息帧进行颜色编码,让您可以轻松了解串行数据信息。与其他解决方案不同,我们的解决方案将协议解码信息与信号分开,而是直接在显示屏上关联波形和协议解码。随着采集长度的扩大或缩短,解码覆盖层将进行调整,以向您显示恰到好处的信息量.
只需单击协议表中感兴趣的 DP-AUX 数据包,即可创建波形的缩放窗口,其中带有颜色编码覆盖,显示数据包类型、命令、AUX 寄存器地址和消息详细信息。
DisplayPort DP-AUX TDMP 可单独用于标准 DP 连接器或 eDP 设计;或与 USB-PD TDMP 一起使用,以分析 DisplayPort over USB-C 设计中 DP-AUX(SBU 线路)和 USB-PD(CC 线路)之间的时序。Msg-Msg 时序测量可用于调试由 USB-PD Alt Mode 事务和 DisplayPort AUX 链路训练之间的时序不当引起的系统互操作性问题。
DisplayPort 2.1 PHY CTS 要求在发送 16 个 SYNC 脉冲的同时,对源和接收器上的 AUX 发射器进行 DP-AUX 眼图测量。QPHY-DP2-SOURCE 自动使用 DPAUX TDMP 解码 DP-AUX 数据,制作所需的眼图模板并进行测量,得出通过/失败合规性结果。
使用 TF-USB-C-HS 或 TF-USB-C SB 测试试样夹具和探测解决方案为 DisplayPort 源/接收器设备系统集成提供最佳解决方案。例如,调试 AUX 和主链路或 AUX 和“Alt Mode”电源传输消息之间的 LTTPR 时序故障。
