Important
Safety
Precautions
The
CDN
must
be
securely
fastened
to
the
earth
ground
before
making
any
connections
to
external
power.
Proper
grounding
of
the
CDN
is
required
in
order
to
prevent
high
leakage
currents
from
presenting
a
potential
safety
hazard
for
test
personnel
.
To
help
establish
proper
grounding,
the
bottom
surface
of
the
CDN
is
unpainted.
In
addition,
the
bottom
plate
has
mounting
holes
for
securely
bolting
the
CDN
to
a
ground
plane.
If
proper
grounding
has
been
achieved,
the
resistance
measured
between
the
CDN
bottom
plate
and
the
ground
plane
should
be
less
than
10
milliohms.
Do
not
connect
the
power
to
the
CDNs
until
all
the
test
equipment
and
EUT
are
in
place
and
electrically
connected.
Avoid
having
any
exposed
live
wires
or
connections.
You
can
use
the
following
procedure.
1.
Connect
EUT
cable
to
CDN
EUT
port.
2.
Connect
the
Test
Generator
(signal
generator,
power
amplifier,
attenuators,
etc)
to
the
RF
port
of
the
CDN.
The
test
generator
output
must
remain
disabled
until
all
connections
are
made.
3.
Connect
accessory
equipment
(AE)
port.
3.1
Maximum
RF
input
Do
not
exceed
RF
input
level
to
the
CDN.
Excessive
RF
input
will
damage
the
CDN
input
and
will
not
be
covered
under
warranty.
To
avoid
accidental
damage
to
the
power
amplifier
or
CDN,
disable
the
RF
output
of
power
amplifier
before
making
any
connections.
Also
make
sure
the
signal
generator
output
is
set
to
its
minimum
level
when
the
RF
is
turned
on.
