The Sigma BSG-100A is a black signal generator which provide six (6) blackburst signal outputs. The outputs are driven from the same internal source to ensure system synchronization. The design of the units provides suitable operation for applications from complex total system timing to laying black on tape. The blackburst signal is digitally derived from a temperature compensated oscillator. These units provide a stable output and do not require any adjustments during operation. The outputs are present when power is applied. The BSG-100A provides outputs per RS-170A / SMPTE 170M standards.
