A grid structure consisting of 23 horizontal and 35 vertical lines is arranged on a white background. 3 grid lines each divide the outer 3 grid rows in the middle. The width of the grid lines is 0.15% of the picture width. The large circular line has a diameter of 83 1/3% of the picture height, the 5 small circular lines have a diameter of 25% of the picture height.
4 resolution wedges are arranged in the large circle at angles of 0°, 45°, 90°, and 135° corresponding to signal frequencies of 2-10 MHz. (The marking ends at 8 MHz and 800 lines).
Utilization
• The test chart is designed for operational adjustment and control of TV cameras.
• The circles permit rough visual appraisal of scan linearity.
• The grid lines serve the purpose of adjusting registration.
• The wedges serve the purpose of resolution appraisal.
