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,

Verify that the leakage
is less
than -107dBm
(1
//V), as indicated by the
Spectrum
Analyzer
by
moving the two-turn loop over the UUT surface

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.

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.
