k.
Program
the UUT to 9.99
kHz deviation. (Skip to step m
if
the UUT has
Option
-651
installed.)
l. Verify that
the Modulation Analyzer reading
is
between 9.3 kHz
and
10.7
kHz.
m.
Program the
UUT
to 0.999 kHz deviation.
n. Verify
that the Modulation
Analyzer reading is between 0,93
kHz and 1 .07
kHz.
NOTE
It may
he
necessary lo
compensate
for
residual
noise
effects
using
the
procedure
presented in the
Modulation Analyzer
manual.
0
.
Disconnect
the LFSSG from the
UUT.
7. Incidental AM
Test
a.
Program the
UUT
for 50-kHz deviation, INT
FM
only, at 1 kHz, a
level of 7
dBm
and a frequency of 11
MHz.
b. Program
the Modulation Analyzer to
measure peak AM in
a0.3-kHz to
3-
kHz bandwidth.
c.
Verify that the
incidental
AM is less than
1%.
8.
Residual
FM
Test
a.
Program the
UUT
for a frequency of 4
MHz and no modulation,
b.
Program the
Modulation Analyzer to measure
rms (or average) FM
in
0.3-
kHz to 3-kHz
bandwidth.
c.
Verify that the
Modulation
Analyzer reading
is
less than 20-Hz
rms
(or
18-Hz average) at the
following UUT
frequencies:
10, 50,
100, 200,
and 244 MHz
d. Verify that the
Modulation Analyzer
reading is less than
lO-Hz rms (or
9-Hz
average) at the following
UUT frequencies:
250, 385,
450,
and 510 MHz
e. Verify that
the
Modulation
Analyzer
reading is less
than
20-Hz rms (or
I8-Hz
average) at the
following
UUT frequencies:
512.03999, 750.03999,
850.03999,
900.03999,
950.03999,
1000.03999,
1025.03999,
and 1049.03999

Analyzer
bandwidth
from 0.05 kHz
to
15 kHz.
