Measuring pixel errors in patch

802BT/802R Video Test Generator User Guide
The analyzer can test and analyze the transmission quality of an external HDMI/DVI
transmit device using a delta error patch pattern. The analyzer captures all or a portion of
an external image (patch pattern) and verifies that all pixels match over a number of
frames. The results are output to an HDMI/DVI display using a special image.
To test an external HDMI/DVI signal using delta error patch pattern:
1. Connect the HDMI/DVI transmit device to the HDMI/DVI Rx connector on the generator.
2. Connect an HDMI/DVI display to the HDMI/DVI Tx connector on the generator.
3. If necessary, set the proper HDMI/DVI signal source and delta error patch parameters
within the generator.
