d.
Adjust the
Spectrum Analyzer
to display the
UUT
signal for
a convenient
reference,
using a
vertical scale
of 10
dB/
division,
a resolution
bandwidth
of
3
kHz, and
a span/division of
5
kHz/division,

Connect
the two-turn loop to the Amplifier
input.

Program
the
UUT
to
+13 dBm,

Verify that the leakage
is less
than
-107dBm

as indicated
by
the
Spectrum Analyzer by
moving
the
two-turn loop over
the
UUT
surface at a

ALTERNATE
OUTPUT LEAKAGE
TEST
RF
leakage
is
verified
by measuring the
induced
signal
in
a
two-turn loop with the
Measuring
Receiver.
REQUIREMENTS
The
output
signal
leakage
must
induce
less
than
I
into
a
l-inch
diameter two-turn
loop,
1
inch
away from any surface of the generator
as
measured
into
a
50-ohm
receiver.

environment.
REMARKS
This
test
is
an
alternative to
the
Output Leakage
test.
Failing this test
indicates
a problem feed-through
filter
or
improper mechanical
assembly,
i.e.,
loose screws,
and/or
damaged
or
misplaced gaskets.
The Measuring Receiver
is
used
to
measure the
UUT
leakage
relative
to a
1
;iV
reference
established at
each frequency.
PROCEDURE
a.
Connect
the
UUT
10
MHz OUT
to the
lO-MHz
timebase input of
the
Measuring
Receiver.
b.
Set the
UUT
REF INT/EXT
switch
to
INT.
c.
Program
the
UUT
to
the
Instrument
Preset
State,
[RCL]
[98].
d.
Program
the
UUT
to
-107
dBm.
e.
Connect the
Measuring Receiver sensor to the
UUT RF
OUTPUT.
