Trigger on any AUX Message (“T”)
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.
Intuitive, color-coded Decode Overlays ("D")
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.
Interactive Protocol Table (“D”)
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.
Automated Timing Measurements (“M”)
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.
DisplayPort AUX EYE PHY Compliance (“P”)
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.
DisplayPort over USB-C System Level Debug
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.
