Importing Custom Bitmaps

You can import your own bitmaps into the 804/804A/804B through the USB interface or from an SD card. The 804A and 804B
support 4K x 2K bitmaps. Note that when bitmaps are imported into the 804/804A/804B, they are rendered at their native
resolution, i.e. they do not scale to the resolution of the video format you have selected as the standard test patterns do.
Therefore, if you want to test with a specific bitmap pattern for each resolution and you want the bitmap to fill the entire
display, you would need to import a separate bitmap of that image for each resolution you wish to test.

Workflow for Importing Bitmaps through USB

In order to import and use bitmaps in the 804/804A/804B you must take the following high level steps (detailed procedures
are provided further below):

Place the 804/804A/804B's USB interface in the Disk mode.

Create a text file called "UserPats.txt" that lists each bitmap stored for use. The name in the file has to match the
name of the bitmap. The procedures below provide an example of this text file.

Transfer the UserPats.txt file to the 804/804A/804B over the USB interface.

Transfer the bitmap(s) over to the 804/804A/804B flash memory through the USB interface.
