The Telefunken FuBK[1] (from the German Funkbetriebskommission for "Television Service Commission") is an electronic analogue television test card developed by AEG-Telefunken and Bosch Fernseh in West Germany as the successor to the monochrome T05 test card in the late-1960s[2] and used with analogue 625-lines PAL broadcasts.
Not as popular as the Philips PM5544, nevertheless it saw widespread use in West Germany (and later reunified Germany) and some other European, Asian, South American and African countries, and by a few commercial TV stations in Australia.[3][4]
