Adjustment Procedure
c. Adjust the leveled sine- wave generator for a
3-
division
(150 mV)
display
at 10
MHz;
then change the
generator frequency to 100
MHz. Do not
readjust signal
amplitude.
d. Press the
XI
0 MAG push button in and usetheAand
B TRIGGER LEVEL controls as needed for a stable
display.
e. CHECK— For a stable display, with
0.1
division
or
less jitter, with
+
and
-
slopes for these modes;
B TRIGGER COUPLING
AC, DC
1. Adjust
the
leveled
sine-wave generator for a
6-

(300
mV) display at 10 MHz; then change the
generator frequency to 100 MHz. Do not readjust the
signal amplitude.
g.
Set the B
TRIGGER
COUPLING
switch

h. CHECK— For a stable display, with 0.1 division
or
less jitter, with both +
and
-
slopes.
i. Set the B TRIGGER COUPLING
switch to HF REJ.

o. Set
the A TRIGGER
COUPLING switch to AC.
p.
Adjust
the leveled
sine-wave generator
for a
3-
division
(150 mV) display at 10 MHz;
then change the
generator
frequency to 100 MHz. Do not
readjust the
signal
amplitude.
q.
Use the A TRIGGER LEVEL
control as needed for a
stable display.
r.

a stable display, with 0.1 division
or
less jitter, with
both
+
and

AC, DC
t. Remove the 10X bnc attenuator
from the
external
trigger
setup and change the A TRIGGER SOURCE switch
to
EXT/10.
u. Use the A TRIGGER
LEVEL control as needed for a
stable display.
v. CHECK—
For a

at 10 MHz; then change the
generator frequency to 100 MHz.
Do not
readjust
the
signal amplitude.
x. Set the A TRIGGER COUPLING
switch to LF REJ
and use the A TRIGGER LEVEL
control as needed for a
stable display.
y.
