Quantum Data 801GC, 801GF, 801GX Creating custom test images, Editing the image knob directory

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.
