INPUT and connect constant amplitude signal gener-
ator.
i. Set frequency of constant amplitude signal
generator to 50 kHz and amplitude to cause 5 inches
of deflection on CRT.

5-72. References. Schematic 3, schematic 6,
table 5-1, figure 5-15 and figure 5-16.
5-73. Procedure.
a. Perform preoperational procedure (Section
III).
b. Set
500/10K
switches (on boards Al and A3)
to 500.
c. Connect equipment as shown in figure 5-15.
d. Set frequency of constant amplitude signal
generator to 250 kHz and amplitude for full-screen
diagonal line (or ellipse) on CRT.
e. If separation of ellipse at center of display
is greater than 0.1 inch, make small adjustments to
A2C8, A2C12, A4C8, and A4C12 until ellipse separa-
tion is less than 0.1 inch.
Note
The procedures in step d above, in para-
graph 5-70 step n , and in paragraph 5-67
step n are interactive. Repeat these pro-
cedures until the requirements of all
three are satisfied.
