Horita CSG-50B Color Bar Sync Generator
Best reference generator for professional analog video production workflows.
The Horita CSG-50B is a professional Color Bar Sync Generator designed for video production workflows. It reliably produces essential analog video and audio reference signals, including SD NTSC RS-170A composite video color bars, blackburst, and sync signals. A crystal-controlled 1KHz audio tone is also included. The generator features front-panel selection for color bar patterns or blackburst and uses precision digitally synthesized signals that maintain RS-170A SC/H phasing without adjustment. A built-in timer automates the switch to black and silence, simplifying tape leader creation and ensuring timing accuracy.
