MODEL 1076 TELEVISION ANALYST
What The Model 1076 Television Analyst Will Do:
Some idea of the versatility of the Model 1076 Television Analyst can be
gained from a quick check of the following list of major equipment features
and uses.
1. As a signal generating source for point-to-point signal injection
trouble shooting techniques throughout a complete TV receiver.
2. Will supply complete (video and audio) R.F. and I.F. signals to
quickly trouble shoot these sections of TV receivers.
3. Will supply a complete test pattern at video (either sync positive or
negative) to inject signal into video stages of TV receivers.
4. Provides a 4.5 me sound channel, F.M. modulated with approximately
25 KC deviation. This audio carrier is modulated from either a
built-in 400 cycle tone generator, or any external audio source.
5. Provides a 400 cycle audio tone signal for signal injection.
6. Separate vertical and horizontal driving pulses are available for
injecting for trouble shooting sweep circuits.
7. Provides composite synchronizing signals either sync negative or sync
positive, adjustable in amplitude, to troubleshoot sync circuits.
8. Provides vertical output stage plate drive signal to check vertical
output transformer, and yoke.
9. Provides vertical yoke test signal to determine if vertical yoke wind­
ings are defective.
10. Provides horizontal driving signal to drive horizontal output trans-
former directly in a TV receiver.
11. Provides B+ boost indicator.
12. Provides hi-voltage indicator.
13. Provides sensitive leakage and continuity test for horizontal output
transformer and yoke.
14. Provides sensitive test to determine if horizontal output transformer
or yoke have internal shorted turns.
15. Provides a high level A.G.C. keying pulse for substitution in keyed
A.G.C. systems.
16. Provides high level test signal to directly modulate TV picture tubes.
17. Built in calibrated low impedance negative bias supply.
18. As a white dot and cross-hatch generator for color TV convergence
adjustments.
19. To trouble shoot and signal trace color circuits in a color TV receiver.
Generates color rainbow pattern and color bar pattern.
20. By the use of the test pattern, TV receivers can be checked for band­
width, resolution, shading and contrast capabilities.
21. Checks the R.F. sensitivity and A.G.C. settings of TV receivers.
22. To check and adjust the vertical and horizontal linearity, size and
aspect ratio of TV receivers.
23. As a stable 11ignal source for trouble shooting intermittents.
24. Will reproduce any 3" x 4" positive transparency as a picture source
to demonstrate the performance capabilities of TV receivers.
25. As an advertising medium to display both picture and sound messages
on the screens of TV receivers in department and retail stores.
26. As the transmitter for video and audio paging systems at conventions,
hospitals and other gatherings.
27. To check performance of community and master antenna systems.
