DPR-100 is a compact-sized and easy to use platform for Audio and HDCP compliance tests of DisplayPort Source devices. It provides all features needed for testing DisplayPort source devices like PC display cards or portable computers. It serves also as an AUX Controller for PHY CTS test automation.

The DPR-100 allows you to monitor all aspects of the DP interface like Link and HDCP status and MSA. You can manually read and set DPR-100 DPCD, sink capabilities, issue varying HPD pulses etc. The Sink Console GUI also includes an advanced EDID parser for viewing and reprogramming its EDID information.




Compact Size

The small size, only 10.5 × 13 × 3.5 centimeters make the DPR-100 an ideal fit for both a laboratory desktop or a production line instrument rack. The only connection needed is the DisplayPort™ input and a USB connection.

Graphical User Interface (GUI) Software

DPR-100 is compatible with two Graphical User Interface (GUI) Softwares. DP RefSink CTS GUI is the user interface for compliance testing and DP Sink Console GUI is meant for development testing and monitoring the Link Training status. Both tools provide the engineer access to all information needed with only a few clicks. This will help the engineer in maintaining effective testing or debugging sessions.

As a development and debug tool, the DPR-100 is connected to a PC through its USB I/F and is operated from a GUI application. This application allows to:

  • Monitor the link status and Main Stream Attributes (MSA) like timing and color-coding used
  • Monitor video CRC and link error count
  • Monitor Audio status
  • Edit and vary DPR-100 DPCD information
  • Repogram EDID
  • Vary DPR-100 capabilities like lane count and max rate
  • Issue HPD with varying duration
  • Report HDCP authentication status
  • Audio output


Compliance Test

DPR-100 is a compact-sized Reference Sink for running Audio and HDCP tests for DUT DP Source devices. DPR-100 with appropriate software is certified by DCP LLC as Authorized Test Equipment for HDCP CTS. The DP RefSink CTS SW GUI allows the user to configure the test to match the DUT capabilities, follow the execution of the test and get an easy-to-read report of the actions during the test and the details of the pass or failure.


AUX Controller for PHY Tests

As a second role, DPR-100 is operating as a DP AUX Controller to automate the DP PHY testing with a compliant PHY Test Equipment. With the AUX Controller firmware, DPR-100 is compatible with Keysight, Teledyne LeCroy and Tektronix oscilloscopes. Please download the applicable firmware from Unigraf Download Page.

Test Automation

The Production Test Command set (PTC) provides a way to control DPR-100 from the user application. This feature enables the use of DPR-100 as a sink in automated software validation tests or long term Quality Assurance reliability tests.
