Sigma BSG-100A Black Signal Generator

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.

The BSG-100A Series accommodates a wide range of line voltage from 90 VAC minimum to 255 VAC maximum. The line frequency range is 50 to 60 Hz. The units utilize an IEC 320 inlet to accommodate the proper power cord set for the line voltage connectors used in any geographical area. The combination of the wide voltage range and universal inlet contributes to the diversity of applications where the BSG-100A will supply a dependable source of black signal. An externally accessible fuse provides circuit protection.

Units are assembled in a stand-alone box. The metal enclosure provides desirable shielding
from external EMI / RFI noise sources.

The connectors are located on the rear panel. BNC connectors are used for the six outputs. Each of the outputs are designed to drive a 75 O load. The outputs must be terminated by a single, end of line 75 O termination to ensure proper signal level. Unused Analog outputs do not require a 75O terminating resistor.

Switch settings are provided for custom configuration. No switch settings change for normal Black Signal operation. Adjustments are provided for custom configuration, however, no adjustments are required for normal black signal generation.
