Automating the PHY Test

DP AUX Controller is a feature for automating DisplayPort™ PHY testing. The function of the AUX Controller is to provide the PHY Test Equipment, that is not a native DP equipment, a communication channel with the Tested unit (UUT). This inhibits the need for the test engineer to manually change the operation modes of the UUT and letting them concentrate on other tasks while the tests are being run.

Dedicated FW for DPT-200

DP AUX Controller function is implemented with a dedicated firmware for Unigraf Reference Sink or Reference Source. The test application in the PHY test equipment commands the firmware to perform actions needed for bringing the UUT in the needed mode.

Compatible BERT TE

Unigraf RefSource AUX Controller feature is used with Unigraf DPT-200 Reference Source test equipment hardware. It is compatible with the following PHY test equipment:
- Keysight (Agilent) J-BERT N4903B using the U7232B and N5990A test automation software packages for DisplayPort™ Physical Layer testing
