2.6 Determine Output Signal Level at STM Antenna Port
The
RF
output
signal
level
should
be
measured
at
the
STM
ANTENNA
port
to
verify
that
maximum
composite
signal
level
is
at
the
required
level.
Use
the
following
procedure
to
determine
the
power
level:
1. Verify
that
RF
ON/OFF
switch
on
the
LPA
in
the
OFF
position.
2. Disconnect
the
antenna
cable
from
the
STM
ANTENNA
port.
3. Connect
a
spectrum
analyzer
or
RF
power
meter
to
the
STM
ANTENNA
port.
(Check
the
input
rating
of
the
test
equipment
and
insert
a
PAD
if
necessary.)
