136 Chapter 8 Analyzing Digital Sources and Cables
To set delta error patch testing parameters:
1. Using a terminal emulator, establish a terminal connection with the generator. Refer to
“Setting up a terminal connection with the generator” on page 14.
2. Enter the following commands to configure the generator to output a digital signal
(HDMI or DVI):
SROP 2 4
This removes analog friendly mode and configures the generator to output either a DVI
or HDMI signal depending on the interface hardware the generator is equipped with
(DVI or HDMI).
3. (optional) Enter the following commands to set the status display mode:
SROP 8
4. Connect the HDMI/DVI transmit device to the HDMI/DVI Rx connector on the generator.
5. Connect an HDMI/DVI display to the HDMI/DVI Tx connector on the generator.
6. Enter the following commands to load a suitable format for the display under test.
FMTL DMT0660 // loads the DMT0660 format for testing
FMTU // applies the DMT0660 format to the generator
7. Enter the following commands to load a suitable static image.
IMGL FLAT // loads the static image for testing
IMGU // applies the image to the generator
8. Enter the following commands to configure the delta patch parameters.
9.
PDSX 128 // sets patch starting at x-pixel 128
PDSY 256 // sets patch starting at y-pixel 256
PDSH 64 // sets patch height at 64 pixel
PDSW 96 // sets patch width at 90 pixels
10. Enter the following commands to run the delta patch test.
PDAU // captures patch of image
ANIG 1 // enables analyzer images
IMGL DeltaErr // loads the DeltaErr image
IMGU // activates the image in the generator
