Do not use this apparatus near water.

Clean only with a damp cloth.

Do not block any of the ventilation openings. Install in accordance with the manufactures instructions.

Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus

(including amplifiers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

Protect the power cord form being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exist from the apparatus.

Only use attachments/accessories specified by the manufacture.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Interference Information:

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

This Class A digital apparatus meets all requirements of the Canadian Interference Causing

Equipment Regulations.

WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

GENERAL:

The BSG-26AN and BSG-26AP are Black Signal Generators which provide six (6) blackburst signal outputs or with the addition of the Optional SDI Output Accessory, two of the six outputs are converted to SDI Digital signals. 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-26AN, NTSC version, provides outputs per RS-170A / SMPTE 170M standards. The BSG-26AP,

PAL version, provides outputs per CCIR 624-4 standards. Specifications are provided in the SPECIFICATIONS section.

POWER:

The BSG-26A 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-26A will supply a dependable source of black signal. An externally accessible fuse provides circuit protection (Figure 1).

FRAMES:

The BSG-26A units are assembled in a stand-alone box. The metal enclosure provides desirable shielding from external EMI / RFI noise sources. See the section on SPECIFICATIONS for recommended operational conditions. The units are capable of rack mounting with the optional RMK-26 Rack Mount Kit. This 1RU rack mount does not require blank panels for unused portions. A total of three (3) Series 26 units may be mounted with a single

RMK-26.

CONNECTIONS:

The connectors are located on the rear panel. BNC connectors are used for the six outputs. When the

Optional SDI OUT kit is installed, Outputs 5 and 6 change to SDI signals. 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 however Unused Digital outputs are best when terminated.
