width shall not exceed 0.010 inch.
f. Reverse connection to X INPUT and Y IN-
PUT. Horizontal deflection shall be less than .015
inch.
5-32. SPOT JITTER AND MOTION.
5-33. Required Result. With X INPUT and Y
INPUT disconnected, spot jitter and motion shall be
less than .010 inch.
5-34. Procedure.
a. Perform preoperational procedure (Section
III).
b. Connect equipment as shown in figure 5-8.
c. Set 500/10K switches (on boards Al and A3)
to 10K.
d. Set sweep time/div of monitor oscilloscope
to 0.1 MSEC/DIV and sweep mode to auto.
e. Short vertical deflection plates together and
observe trace with optical comparator.

g.
Remove sweep from X INPUT and connect
to Y INPUT.
h. Short horizontal deflection plates together
and observe trace with optical comparator.
i. Remove short from horizontal deflection
plates and observe increase in trace width. Increase
in trace width shall not exceed 0.010 inch.
5-35. DEFLECTION AMPLIFIER DYNAMIC RANGE.
5-36. Required Result. The dynamic range shall
extend at least to 11 /2 screen diameters from center
screen.
