Receiver Adjustment
14.
Adjust
EEPOT
5
for -6 dBm at Line
2
+/-.
NOTE
Perform
step
15
and
step
16
if
the station is
equipped
with
the Secure
Option C514, otherwise
proceed
to
step
17.
15.
Without changing
the
RF
input level,
inject
a
coded eye pattern (using the
proper encryption algorithm) and adjust
EEPOT C
for -6
dBm
at
Line
2
+/-.
16.
Repeat
step
13
and step
14.
17.
Set the
PL Dis/Xmit
switch
to the center (off) position.
Remove
the
RF
signal from the
receiver
18.
Adjust
EEPOT
8
for
a
status tone
(2175
Hz)
level of
-19
dBm
at
line
2
+/-.
19.
Adjust EEPOTs
2
and
3
to 00.
20.
Set the
PL Dis/Xmit
switch
to
PL Dis.
Measure and record the rms noise voltage level
at
Line
2.
21. Inject an on-channel
0.1
uV
signal without modulation
at the receive
antenna port.
22. Increase the
RF
level until
the
Line
2
output level
decreases
by
20
dB from
the
level
recorded in step
20 (20
dbq).
This
correlates to 17
dB
SINAD.
23.
Adjust
EEPOT
3
until
the R1
UN
SQ
MUXbus
bit turns
off.
NOTE
Perform
step 24
if
the station is
equipped with Secure
Option C514 and
codeplug
option
X20AZ_SP,
otherwise proceed to step
25.
24.
Without changing
the
RF
input level,
inject
a
coded eye pattern and adjust
EEPOT
2
until
the
RPT UN
SQ MUXbus bit
turns off.
25.
Disconnect all
test equipment.
Alignment
is complete.
