802BT/802R Video Test Generator User Guide 617

Check511

Description Consists of five small boxes in the corners and at the center of the active video. The boxes

are on a black background. Each box consists of alternating black and white pixels that

form a very fine checkerboard. The secondary version inverts the image, creating a white

background. The colors of the individual pixels in the boxes also are inverted.

Test Verify monitor resolution

Purpose The resolution of your monitor should meet or exceed the design specifications.

Method First adjust the brightness, contrast, and focus to their correct settings. You should be able

to see individual and distinct pixels in each of the boxes. Failure to see distinct pixels may

indicate you have a defective video amplifier, focus correction circuit, or picture tube.

Note: If multi-colored areas appear on a mask-type color picture tube, you may have a

problem with convergence or you may be exceeding the resolution of the picture tube.
