Purpose: The VAC Model VB/BBG-3 Black Burst Generator provides necessary signals for sychronizing genlockable color or monochrome video equipment. Proper synchronization enables users to make clean, accurate, switches and transitions between video sources and facilitates color field accuracy in edit systems.
The VB/BBG-3 black burst generator provides four black burst outputs guaranteed to meet RS-170A specifications including SC/H phase, frequency accuracy, rise times, and amplitudes from the moment the unit is first powered. The popular VAC Brick package, makes it ideal for field and desktop video installations.
New Power System: The supplied AC adapter should be plugged into the coaxial power jack. If you need to use a power source other than the AC adapter, the input voltage range for the VB/BBG-3 is 12 to 24 Volts DC grounded or ungrounded, either polarity. The typical current draw is less than 100 mA.
