Creating custom test images
User defined custom test images can be created and
edited. The images are made up of one or more
drawing primitives. Some of the primitives in the
current firmware are single pixel dots, lines, rect-
angles (filled and unfilled) and ovals (filled and
unfilled). The grayscale and color tables used in the
image can be selected by the user. The custom test
images are saved in non-volatile memory. Custom
images can be added to the list of images that can
be selected with the Image knob directory or to a
test sequence.
Editing the image knob directory
The default operating mode of the 801G* uses the
bottom knob to select images (test patterns) from an
internal image knob directory. The default knob
directory includes all of the standard built-in test
images. The directory can be edited to include
anycombination of built-in and / or custom images
in any order desired.
Creating a test sequence
The 801G* can be programmed to run in a test se-
quence mode on power-up. The test sequence mode
allows an operator to go through a defined series of
signal formats and test images using a single knob.
This mode of operation is useful in a manufacturing
test environment where the same test procedure needs
to be repeated on many identical displays. Multiple
test sequences can be stored in the generator and
selected by the operator.
