Controls & Indicators
The following main operable controls are provided on the front panel of the Model 1076 Television Analyst:
1. POWER SWITCH: Labeled Off-Stby-On, allows the unit to be kept ready by keeping the tubes hot without signal radiation. The pilot light illuminates in either the “Stby” or “On” position.
2. R.F.- I.F. SELECTOR SWITCH: Tunes the Television Analyst to channels 2 through 6, 7, 8, 12, or 13. In the I.F. position, the unit transmits on I.F. Both R.F. and I.F. frequency generators are off in the “Off” position.
3. I.F. TUNING: Tunes any I.F. frequency between 20 mc and 48 mc.
4. VIDEO CONTROL: Determines the amount of video or contrast of the picture.
5. HORIZONTAL CONTROL: Fine frequency adjustment of the horizontal oscillator circuit.
6. VIDEO POLARITY (+ or -) SWITCH: Determines whether the video output signal will be positive or negative polarity.
7. SYNC AMPLITUDE CONTROL: Adjusts the amplitude and phase of the sync signal, calibrated in peak-to-peak volts.
8. COLOR OFF-ON SWITCH: Turns on the color signal for a color rainbow or color bar display.
9. AUDIO SWITCH: Labeled “Off-Audio-Tone”, controls audio signal transmission and modulation.
10. R.F. ATTENUATOR: Determines the amount of signal output of both R.F. and I.F. frequencies.
11. NEGATIVE BIAS CONTROL: Selects a negative voltage to ground between 0 and 50 volts.
12. VERTICAL DRIVE AMPLITUDE: Adjusts the amplitude of both the vertical grid drive signal and the vertical plate drive signal.
13. PLATE DRIVE SELECTOR: Provides a choice of a vertical or horizontal plate drive signal to drive a horizontal output transformer, with an “Off” position.
14. CALIBRATE CONTROL: Calibrates the shorted turns tester and the instrument for leakage tests on flybacks and yokes.
