d.
On
the
spectrum
analyzer
,
press
4
PEAK
SEARCH
5
to
move
the
marker
to
the
peak
of
the
520
MHz
signal.
e.
Check
that
the
frequency
is
520
MHz,
the
level
is
015
dBm
6
0.2
dB
,
and
the
harmonic
levels
at
480
MHz
and
560
MHz
are
lower
than
0
dBc
(lower
than
the
520
MHz
signal
level).
The
trace
displayed
on
the
spectrum
analyzer
should
be
as
shown
in
Figure
7-13.
If
the
signal
is
good,
continue
with
6.
Check
the
EXT
REF
Operation.
If
the
signal
level
is
out
of
the
limits
,
perform
the
520
MHz
Level
A
djustment
(see
the
A
djustments
and
Correction
Constants
chapter).
If
the
adjustment
is
successfully
completed,
continue
with
6.
Check
the
EXT
REF
Operation.
If
the
adjustment
fails
,
the
X13
multiplier
is
faulty
.
Replace
A5.
If
the
signal
is
bad,
the
X13
multiplier
is
faulty
.
Replace
A5.
6.
Check
the
EXT
REF
Operation
When
an
external
reference
signal
(10
MHz,
0
dBm)
is
applied
to
the
EXT
REF
input
connector
on
the
rear
panel,
the
message
\ExtRef "
appears
on
the
display
.
When
the
external
reference
signal
is
removed,
the
\ExtRef "
message
disappears
.
P
erform
the
following
steps
to
verify
the
operation
of
the
EXT
REF
input:
a.
Connect
the
equipment
as
shown
in
Figure
7-15.
Then
check
that
the
\ExtRef "
message
appears
on
the
display
.
If
Option
1D5
is
installed
in
the
4396B
,
connect
the
cable
between
the
EXT
REF
Input
connector
and
REF
O
VEN
(Opt
1D5)
connector
.
b.
Disconnect
the
cable
from
the
EXT
REF
input.
Then
check
that
the
\ExtRef "
message
disappears
.
If
the
\ExtRef "
message
appears
and
disappears
correctly
,
the
EXT
REF
circuit
probably
working.
At
this
point,
the
A5
synthesizer
is
veried.
If
the
\ExtRef "
message
does
not
appear
,
inspect
the
cable
and
connections
between
the
EXT
REF
input
connector
and
A5J4.
See
Figure
7-3
for
the
location
of
A5J4.
If
the
cable
and
connections
are
good,
the
most
probable
faulty
assembly
is
A5.
Replace
A5.
