7. HORIZONTAL DRIVE. (C-219). This capacitor controls the hori­
zontal drive to the horizontal output tube. Adjustment of this con­
trol establishes the operating conditions for the horizontal output tube
and is effective in adjusting the horizontal linearity.
8. L-201 (Horizontal Oscillator Stabilizing coil). This coil assists in
stabilizing the Horizontal oscillator frequency and is slug tuned.
9. V. SIZE. (R-207). This control adjusts the size of the scanning
raster.
10. V. LINEARITY. (R-206). This control adjusts the vertical linearity
of the scanning raster.
11. R-211. This is the coarse Horizontal Frequency Control and is
adjusted to permit the front panel Horizontal Control to be centered
in its range.
12. BEAM CURRENT. (R-221). This control adjusts the beam current
of the 5BKPV1 scanning tube.
13. The centering magnets are located to the rear of the deflection yoke
and control the centering of the scanning raste, and therefore the
centering of the reproduced picture.
14. The R. F. channel adjustments and the I.F. adjustments are slug
tuned coils accessible through the holes in the shield of the R.F.
assembly. The I.F. slug and channels 2, 3, 4 and 5 are the top slugs
while the bottom slugs cover channels 6, 7, 8, 12 and 13.
15. R-218. This control adjusts the sensitivity of the Leakage-Continuity
Test.
16. R-215. This control adjusts the voltage to the cathode of V-3A to
calibrate the Sync Amplitude control on the front panel.
HOW TO SET UP THE TELEVISION ANALYST
The Television Analyst is an economical equivalent to a standard television
field. Therefore, it follows that the operation and adjustments of this instrument
are entirely different from the average test instrument found in the TV service
field today. The adjustments which will be covered in these instructions in
detail are quite simple. FAIL URE to make these few adjustments may
result in extremely poor performance of the equipment. IT IS, THEREFORE,
MANDATORY THAT THESE ADJUSTMENTS BE MADE FOR PROPER
OPERATION OF THE TELEVISION ANALYST.
The Television Analyst is an economical equivalent to a standard television
station. Just as it is necessary for broadcast personnel to initially and periodic­
ally check and adjust their equipment, so too it is imperative that the same
type of procedure be used with the Analyst. A decent respect for the tolerance
of this equipment should be acquired by the owner so that he may understand
its features, advantages and limitations.
The adjustments that are made at the factory are not necessarily the adjust­
ments that will satisfy the conditions in your area. Not all broadcast stations
throughout the country produce a test pattern that is identical in setup. It· is
necessary to make adjustments on the Television Analyst to set it for linearity,
size· and centering to match your local conditions. These adjustments are
made in the following manner:
1. All areas have available at some time during the week a standard
test pattern from a local TV station. We take advantage of this
to setup to local conditions. Find out when this pattern is avail­
able, and allow the Analyst and a standard TV set to warm up for
5 to 10 minutes before using.
