Black signal generator with 8 outputs, NTSC are part of Sigma's Series 2100 and 26 families which include models for switching, distribution, signal processing, timing and testing. The BSG-21 is function- and frame-compatible with all other SERIES 2100 modules. The system designer can combine analog and digital distribution, analog and digital switching, signal processing and system timing within the same frame or frames, such as the SS-2100-6 or SS-2100-16. The BSG-26, like all Series 26 models, functions as a stand-alone product or may be combined in Sigma's RMK-26 Rackmount Kit to meet specific system requirements. All models are extremely stable and suitable for the most stringent studio environments. The Blackburst ouputs may be used to drive cameras, switchers, slave generators or any device capable of being genlocked via a blackburst signal.
