a.
Connect
the
multimeter
test
leads
across
the
center
and
outer
conductor
of
the
attenuators
INPUT
connector.
See
Result
should
be
50
±
2
Ohms
b.
Connect
the
multimeter
test
leads
across
the
center
and
outer
conductor
of
the
Attenuators
OUTPUT
connector.
Result
should
be
50
±
2
Ohms
c.
Connect
the
multimeter
test
leads
across
the
INPUT
center
conductor
and
the
OUTPUT
center
conductor.
Result
should
be
93.7
±
2
Ohms
4.
Record
the
value
of
the
resistance
before
the
attenuator
is
put
into
service.
Compare
subsequent
values
with
the
latest
reading.
If
the
values
vary
more
than
2
ohms
this
could
be
an
indication
of
a
failing
Attenuator.
