Debug and Test Controller GUI

The desktop user interface for DPR-120 is called Debug and Test Controller (DTC) GUI. It provides the user access to all link status information and ways to control the features of the DPR-120 sink for testing DUT capabilities. It also features an AUX Channel Monitor for evaluating the handshake in the upstream link. DTC GUI is also the user interface for Link compliant tests.

DTC GUI allows the user to evaluate the details of both the upstream DP Link training status and the streams sent by the Source. The user can monitor and log the changes in Main Stream Attributes (MSA), Video Status and CRC of color components. Both the EDID and the DPCD data of the DPR-120 Sink can be altered.

All these are valuable features for testing the DUT source with various sink capability scenarios. Debug and Test Controller GUI is also the user interface for DP 1.2 Link Layer CTS Extensions tests.
