NJ-10-100A is designed for operational adjustment and control of TV cameras. It consists of circles permitting rough visual appraisal of scan linearity, grid lines serving the purpose of adjusting registration and wedges serving the purpose of resolution appraisal.

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 600 lines).

UTILIZATION

  • The test chart is designed for operational adjustment and control of TV cameras.
