GUI, FW and HW


Unigraf CTS tools consist of three components:

  • Windows graphical user interface (GUI) application,
  • Target firmware (FW) for the DisplayPort™ controller 
    chip located in the TE.
  • Unigraf Reference Sink or Reference Source
    Test Equipment (TE) hardware

The actual tests are implemented by the FW, while system control and status reporting are done by the GUI. The FW implements both the functions needed in the CTS tests and the normal functionality as DP video generator or frame grabber.
