摘要

描述УЭИТ.svg	English: So named “universal electronic test table” used in TV broadcasts in USSR. The card features the following elements: Grid box - makes up the background of the table. Allows adjustment of CRT convergence and easy reference for test card elements by "line" numbers (as indicated below); Small circles - at lines 3, 4, 17, 18, they have the same function as the Gratings; Center crosshair - in the center of the large circle, allows further convergence and image centering adjustments on CRTs; Table border - fiducial marks for setting proper image geometry and overscan; Circles - provide a way to correct vertical and horizontal raster scan distortions; Color bars - two sets of bars (75% saturation at lines 6 to 7; 100% saturation at lines 14 to 15) to adjust color saturation; Gray scale - a set of bars on line 8, that allow setting brightness, contrast, white balance and black level; Contrasting color stripes - located at line 9, they allow checking of color transitions; Slanted stripes- located at lines 10 to 11, they allow checking of interlace accuracy ; Smooth color transition - at line 12, it allows to check the color linearity over the full color spectrum, or a green to magenta transition; Gratings - located at line 13, these help to assess resolution and image focus. They are formed by bursts of sinusoidal signals with frequencies of 2, 3, 4 and 5 MHz, corresponding to resolutions of 220, 330, 440 and 550 horizontal TV lines; Black and white squares- alternating squares at line 16, to evaluate the frequency response of the video chain; Русский: Один из вариантов универсальной электронной испытательной таблицы. Внимание! Тестовая таблица приведена в разрешении 768 × 576 пикселей, т.е. кол-во пикселей в строке превышает возможности полосы частот телевизионного канала (720).
