Three Vertical Bar Signal
As defined in IEC 60107-1:1997, this signal produces three equidistant vertical white bars on a black background. Each bar is 1/6 of the picture width. It features a 50% APL and includes reference white level, suitable for luminance and signal level calibration. For SECAM, a subcarrier is superimposed corresponding to black and white levels.
