Step
25 parts h through j
REPTACE
WITH:
The
following new
parts h through tn
h.
Set the 7B53A for a
sweep
rate of 0.1 microsecond/division
with the X10 magnifier on; set the deflection
factor of the
7A15A
as
necessary so the markers are about two divisions in
amplitude for the rest of step 25.
i. CHECK-CRT display
for one marker each
division over the
center eight
divisions.
j.
ADJUST-For
SN B080000-up-C588 for one marker
each division
(For
SN
below
B080000, adjust C568
and C588 for one marker
each division while maintaining approximately equal capaci
tances).
Use low capacitance adjustment
tool for
all adjust
ments in this step.
k.
Set the 7B53A for a sweep rate of 0.05 microsecond/division
with X10 magnifier on.
l.
ADJUST-For
SN B080000-up-C566 and 0586 for one
marker each
two divisions while maintaining approximately equal capaci
tances.
(For SN below B080000, readjust C568 and C588 for
best
compromise between
5
nanosecond and 10 nanosecond timing).
m.
Repeat parts j,k, and 1 to
achieve the best compromise for
5
nanosecond
and
10 nanosecond
timing over the center 8
horizontal
divisions.
