: INSTRUCTION MANUAL For The CG126 COLOR GENERATOR INSTRUCTION MANUAL for the CG126 COLOR GENERATOR Recognizing the need for a stable, low cost generator that produces all necessary patterns for accurate convergence and trouble shooting in the home, SENCORE has developed the CG126 Standard Color Bar Generator. The CG126 is the smallest, lightest, and least expensive generator of any on the market and yet it provides the same stable patterns of generators costing twice as much. The CG126 provides the following patterns: Ten Standard Color Bars: The type and phase that is fast becoming the standard of the industry. Crystal controlled keyed bars (RCA type with 30 degrees phase change between each) as explained in most service lit erature, offer a complete gamut of colors for every color circuit test. Adjustable Size White Dots: New stabilized dots, a must for convergence, are created by new SENCORE counting circuits. The size of the dots are adjustable from the rear of the unit. Crosshatch Pattern: A basic requirement for fast CRT convergence, and, also, for sweep linearity and "overscan" adjustments. Vertical and Horizontal Bars: An added feature to speed up convergence, not found on many other color generators. SPECIFICATIONS RF Output: Frequency is factory set to Channel 4. It can easily be changed to Channel 3 or Channel 5, if Channel 4 is used in your area. Modulation: Any one of five patterns: Color Bars, Dots, Crosshatch, Vertical Bars, or Horizontal Bars. Tube Complement: 6-12AU7A, 2-12AZ7, 1-12BE6 Diode Complement: 2-1N295 Crystal Complement: 1-189KC t .005% for timer, 1-3563.795KC .001% for color Lars. Power Consumption: 35 watts at 117 VAC line. Size: 11 inches wide by 8 inches high by 6 inches deep. Net Weight: 9 1/2 pounds. CONTROLS ON THE CG126 The CG126 is an extremely easy generator to set up and use. Only three front panel controls are needed in normal use. These are the AC power switch, the Pattern switch and the Color Output control. Additional adjustments for the timing circuits, and for dot size, are available on the rear of the unit, but these are all factory set and normally do not need to be changed. 2 AC Power Switch: The AC power switch is used to turn the unit ON and OFF. It also has a middle STANDBY position which is used whenever you wish to disable the pattern and RF carrier, but still keep the tube filaments hot for instant use. Pattern Switch: The pattern switch selects one of the five patterns avail able to modulate the RF carrier. Composite sync is fed to the modulator at all times so that the patterns will not jump or fall out of sync when switching from one pattern to another. The following patterns are available on the CG126, each for a
