The GB module of the RUBIDIUM Series serves as a versatile master black burst and tri-level generator. Gen-locked to a system reference, the GB module delivers video signals in a highly accurate manner. With the included input and output connections the unit was intended for a standalone functionality, or as a component of a comprehensive generator system. The GB ’s main task is controlling external SPGs with the aid of GPS and 10MHz signals. That way, in addition to the Timecode, Word-clock, and NTP reference signals, the RUBIDIUM System can provide black burst and tri-level from a single source as well.
