NOTE
For
53348
instruments equipped with Option
060,
set Signal Generator
amplitude to
40.0
mV
+
0.4
mV. Terminate the unused Channel
A
and
B
rear inputs with
50R
loads.
2.
Set the
5334B
as follows:

3.
Connect the Signal Generator output to the
5334B
Input A. Connect Time Base as shown in
Figztre
5-8.
4.
Adjust
AIR130
(CH A) for a
5334B
front panel display of
70.000 000
MHz
+
4
Hz at both the positive and
negative slope settings.
5.
Decrement the Signal Generator amplitude by
3
mV rms.
6.
Adjust
AIR130
(CH A) for a
5334B
front panel display of
70.000
000
MHz
+
4
Hz at both the positive and
negative slope settings. If this adjustment is not possible because the signal level has dropped below the
Counter's sensitivity limit, go to step
10.
Otherwise, continue on to step
7.
7.
Set the Signal Generator frequency to
104
MHz.
8.
Adjust
AIR130
(CH A) for a
5334B
front panel display of
104.000 000
MHz
+-
4
Hz at both the positive
and negative slope settings. If this adjustment is not possible, go to step
10.
Otherwise continue on to step
9.
9.
Set the Signal Generator frequency to
70
MHz and repeat steps
5
through
9
until adjustment is no longer
possible and this loop is exited from step
6
or
8.
10.
Increment the Signal Generator amplitude in
0.3
mV
rms steps until Counter displays a stable frequency
count.
11.
Set the Signal Generator frequency to
104
MHz.
12.
Adjust
AIR130
(CH A) for a
5334B
front panel display of
104.000 000
MHz
t
4
Hz at both the positive
and negative slope trigger settings. If this adjustment is not possible, repeat steps
10
through
12
until this
ad-
justment is completed and then continue
with
step
13.
13.
Set the Signal Generator frequency to
70
MHz.
14. Adjust
AIR130 (CH
A)
for a
5334B
front panel display of
70.000
000
MHz
k
4
Hz at both the positive and
negative slope settings. If this adjustment is not possible, repeat steps
10
through
14
until this adjustment is
completed and then continue with step
15.
15.
Set the Signal Generator frequency to
70
MHz and the amplitude to
28.0
mV
+.
0.3
mV.
