The Extron
BBG 6 A
Blackburst, Color Bars, and Audio Generator offers six broadcast
quality, NTSC or PAL blackburst output signals, allowing a variety of video equipment to be
genlocked to a common reference signal. The blackburst signal consists of three reference
signal components: vertical sync, horizontal sync, and color burst. The first two outputs can
also provide broadcast quality NTSC SMPTE Color Bars or PAL full-field Color Bars test patterns,
selectable via a DIP switch. Additionally, the BBG 6 A includes a 1 kHz audio generator with
balanced or unbalanced audio on captive screw connectors. Part of the VersaTools
