Burst Generator. The SG-3 is a low cost Color Bar/
Black Burst Generator that produces the SMPTE

These units may be used as a genlock reference, to
“lay down” bars on tape, or to correctly set the color
and brightness o f video monitors. They may also be
used as a video source for testing cables and
equipment. The rear panel of the SG-3 has a single
BNC connector that is selectable between SMPTE
Color Bars and Black Burst. The rear panel of the
SG-7 has seven (7) BNC connectors, 1 SMPTE
Color Bars, and six (6) Composite Black Bursts.
Both units operate on 12 volts DC from an AC
adapter (included). The output is a standard NTSC
video signal (1 Vpp @ 75 Ohms). The SMPTE Color
Bar output signal includes 75% color bars, reverse
Blue bars, 100% White, Black, -I & +Q signals, and
the pluge (pronounced “plooj”) pulse signal.
