Key Facts This option extends the functionality of the R&S®UPP-B4 option to include generator signals and measurements that go beyond purely audio operation:
  • Whereas the basic functionality when generating HDMI test signals is the automatic generation of suitable info frames, the R&S®UPP-K45 option allows info frames to be displayed and edited. This makes it possible to test how DUTs respond to apparently incorrect data and to determine to what extent the corrections required in the conformance tests work
  • Received info frames and stream headers can be displayed and evaluated
  • The bit error rate testing (BERT) function measures the bit error rate across an HDMI transmission path by transmitting defined bit patterns
  • The lip sync function measures the time offset between the video and audio signal, because time differences between voice and mouth movement are disturbing. The generator provides a test signal that can be set within wide ranges
  • The pattern generator function generates a large number of multichrome and moving video test patterns
  • The pixel clock, Hsync and Vsync frequencies and the timing parameters of the measured video signal can be displayed
