Русский: УЭИТ, оцифрованная со стойки «Перспектива»
English: UEIT test card 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;
