Measuring pixel errors in patch
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.
• See “ Starting the Analyzer Setup Utility ” on page 112 for steps on viewing the
current analyzer configuration.
• To edit HDMI/DVI signal source parameters, see “ Setting up analyzer to measure
timing ” on page 114.
• To edit delta error patch parameters, see “ Setting delta error patch parameters ” on
page 123.
4. (HDMI only) If desired, monitor the video signal received on the HDMI Rx connector
(see “ Monitoring HDMI analyzer signal input ” on page 110).
5. Generate a static image from the HDMI/DVI transmit device.
6. Using the Format knob, select an appropriate format for the connected HDMI/DVI
display.
Note: To automatically configure the Format knob list based on the EDID structure of
a DDC-compliant display, hold down the R key, then press and release the ACS key.
