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 st ructure of
a DDC-compliant display, hold down the R key, then press and release the ACS key.
