Introducing the Unigraf DPR-120 DP 1.2 Test Device (Full featured DisplayPort™ 1.2 compliant Reference Sink)
Full DP Reference Sink Functionality
DPR-120 is a full featured DisplayPort™ 1.2 compliant Reference Sink. It provides all features needed for testing DisplayPort™ 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 enables monitoring the performance of the DUT.
Monitor All MST Streams
The DPR-120 allows the user to evaluate the details of both the upstream DP Link and also any MST Stream received. Main Stream Attributes (MSA), Video Status and CRC of color components can be
monitored and logged. The user can additionally monitor, parse and edit both the EDID and the DPCD data of the DPR-120 Sink. All these features are valuable for testing the DUT source with various sink capability scenarios.
Certified Test Tool
Debug and Test Controller GUI is also the user interface for DP 1.2 Link Layer CTS Extensions tests.
VESA has certified Unigraf DPR-120 Reference Sink as the Authorized Test Tool for testing Link layer CTS 1.2 Core and 1.2 Extension Set 1 revision 1.1
Key Features
Debug and Test Controller GUI
DPR-120 is connected to a PC through its USB. The Debug and Test Controller GUI allows the user to:
- Monitor Upstream Link status
- Select any received stream for preview
- Monitor and log the Video Status and Main Stream Attributes (MSA) of any stream received
- Monitor and log video CRC and link error count
- Monitor and edit DPR-120 EDID and DPCD information
- Vary DPR-120 capabilities like lane count and max rate
- Issue HPD with varying duration
- Report HDCP authentication status
Key Benefits
AUX Channel Monitor
By enabling the optional feature the user can analyze MST stream allocation and AUX Channel communication in the upstream link
Link CTS Software
The optional DisplayPort™ RefSink CTS tool software enables a set of DP 1.2 CTS Link Layer compliance tests. Please refer to the documention of the RefSink CTS Tool for details about
the supported tests.
