DPA-400 and its AUX Channel Monitor user interface (GUI) provides a compact, pocket-sized tool for recording and analyzing DisplayPort AUX channel traffic. It enables the user to monitor, capture, and document all AUX Channel transactions over a DisplayPort link. AUX Channel Monitor GUI detects, timestamps, and parses all DisplayPort Configuration Data (DPCD) reads and writes, Multistream (MST) Sideband Channel Communication, and EDID reads. The GUI is able to parse DPCD registers for DP versions up to 2.0. It decodes HDCP 1.3 and 2.3 messages and DP Sideband Channel Communication messages. The activity of the Hot Plug Detect (HPD) signal and optional user-defined input signals will also be tracked and time-stamped. Unigraf’s AUX Channel Monitor is a mandatory tool for any engineer that wants to verify and/or debug Compliance Tests and Interoperability Test results. By analyzing the details of the source-sink interaction, the designer is able to fully confirm the behavior of both parties. When the content of each read and write are available in detail, there will be no room for guessing.

DPR-120 is a fully-featured DisplayPort™ 1.2 compliant Reference Sink. Verify DisplayPort interfaces up to 4K@60Hz. It provides all features needed for testing DP Multistream (MST) source devices like PC display cards or portable computers. The Debug and Test Controller GUI is the user interface of DPR-120. It provides the user with a multitude of valuable tools for monitoring the performance of the DUT. VESA has certified DPR-120 as the Authorized Test tool for testing Link layer CTS 1.2 Core and Extension Set 1 revision 1.1. Unigraf’s DPR-120 DisplayPort Reference Sink is an Authorized Test Tool for DP 1.2 Link Core and Link Ext1 CTS tests for testing DisplayPort source devices. DPR-120 Debug and Test Controller SW (DTC) is the graphical user interface (GUI) for controlling the DP 1.2 Link CTS tests with DPR-120 Reference Sink. DPR-120 DTC also has many powerful debug features for monitoring the status of the tested unit (DUT) and the test procedure.
