GENERAL
The CSG-50 provides an economical means of obtaining high quality split-field SMPTE color bars, full-field EIA color
bars, blackburst, and composite sync signals. The CSG-50 can be used with HORITA SMPTE time code reader-generators
for striping video tapes with color bars and/or blackburst, and time code.
Color bars and blackburst are examples of composite video signals. Composite video is a combination of several signals
made into one. It contains the picture's black and white information, called luminance, color information, called
chrominance, and timing information, called horizontal and vertical sync and blanking.
Composite sync is -4 Volt pulse signal made by combining horizontal and vertical sync into one signal. It does not provide
luminance, chrominance, or blanking information.
Typical applications of the CSG-50 include use as a "house sync" generator in a video editing system to synchronize
operation of various video switchers, special effects generators, VCRs/VTRs, cameras, monitors, video edit controllers,
video titlers, time-base correctors, SMPTE time code, and other types of professional video equipment.
The CSG-50 can also be used as a video test signal generator to align and maintain video equipment in the studio, or as a
portable color bar generator for use in the field.

FEATURES
* Generates color bars, blackburst, and composite sync signals, as well as a 15Hz reference frame timing signal.
* Front panel selection of full-field or SMPTE color bar patterns or blackburst (color black) video output.
* Video signals generated by the CSG-50 are in accordance with the industry standard EIA RS-170A video timing
specification.
*
Fully RS-170A SC/H phased and always correct. Never needs adjustment.
* SMPTE color bars meet SMPTE specification EG-1-1990.
* Full-field color bars meet EIA RS-189A specifications for video levels and colors.
* Blackburst signal has a standard setup level (black level) of +7.5 IRE units.
* A unique feature of the CSG-50 is the automatic timer. The timer switches the CSG-50 from color bars to blackburst
after a delay of 30 or 60 seconds following activation of the front panel timer switch. This feature is especially
convenient for "pre-striping" a tape with SMPTE time code and with a video leader consisting of color bars followed by
black for the remainder of the tape.
* Operates from a small AC power adapter, which is included, or can be operated in the field from 9-to-14 volts DC battery
power.
* Available in Desktop (CSG-50), Rackmount (RM-50/CSG), or Shortrack (SR-50/CSG) models.

CONNECTING THE CSG-50
3.1 Connecting Power
Included with your CSG-50 is an AC power adapter that provides a 9 volt, 500 milliamperes DC output. This adapter is
equipped with a miniature phone plug with the "+" (positive) voltage output connected to the front tip of the plug.
Insert the power plug into the CSG-50 "+9V POWER" connector and plug the adapter into 110-120 volt, 60-Hz AC power.
