Overview & Features

Debug DisplayPort 1.4 PHY and Link in Real-Time


Quickly resolve challenges in early designs with GRL’s DisplayPort (DP) 1.4 Protocol Decode Automation Software, the only tool available for oscilloscope-based DP Link Layer/protocol analysis and debug of 1, 2, 3 and 4 lane DP designs. GRL’s solution is compatible with leading vendors high performance real-time Oscilloscope platforms.

Overcome the limitations of using a traditional oscilloscope to debug DisplayPort 1.4 designs. Save time and eliminate errors by viewing DisplayPort micro-packets at the protocol level along with time-correlated physical layer signals. GRL-DP-DEC helps quickly troubleshoot DisplayPort 1.4 protocol problems back to their timing or signal integrity root cause.

GRL-DP-DEC is the only tool that allows developers to decode Multi-Stream Transport (MST) traffic on a real-time scope. MST allows streaming of multiple independent video streams from a single Display-Port output. Implementing MST presents design challenges both at the electrical and protocol level with strict timing budgets and bandwidth requirements. GRL-DP-DEC helps overcome these challenges with easy to use MST traffic capture and analysis.
