PdsCrt2 Description Special test image developed per customer specifications. Persist Description In the primary version, 15 small white boxes move back and forth between diagonal guide lines. The lines form 15 side-by-side tracks. The size of each box is scaled to the light meter box size set by the MSIZ system parameter. The image does the following: • The box in the center track (marked “1X”) moves one scan line vertically and one pixel horizontally for each vertical frame of refresh. • The seven boxes to the right of the center track (marked “2X” through “8X”) move 2, 3, 4, 5, 6, 7, and 8 pixels and lines per frame, respectively. • The seven boxes to the left of the center track (marked “/2” through “/8”) move one scan line vertically and one pixel horizontally for every 2, 3, 4, 5, 6, 7, and 8 vertical frames of refresh, respectively. These boxes are at the bottom of the tracks. In cases where the next move would cause the box to move beyond the end of its track, it immediately reverses and moves the correct distance in the opposite direction for the next frame. A continuously-running counter appears in the upper left corner of the image. The number shown is the number of vertical frame refreshes that have occurred since the generator was first powered up. The secondary version draws a black image on a white background. 802BT/802R Video Test Generator User Guide 675
