Abstract
An arrangement for producing color television test serials of the pal system, in which automatic error compensation during decoding is eliminated, characterized in that it includes an electronic switch that erases the color information of one out of every two lines, and because the interruption frequency (fh/2) is inverted with the image frequency (fv/2) in such a way that a polarity change of the ufv modulation component occurs from image to image.
