Testing
The
performance
specifications
described
in
this
section
are
valid
while
the
antenna
is
mounted
in
the
host
device
with
the
antenna
feed
cable
routed
in
its
final
application
configuration.
The
following
guidelines
apply
to
the
tests
in
this
section:
•
Perform
electrical
measurements
at
room
temperature
(+20°C
to
+26°C)
unless
otherwise
specified
•
For
main
and
diversity
path
antennas,
make
sure
the
antennas
(including
contact
device,
coaxial
cable,
connectors,
and
matching
circuit
with
no
more
than
six
components,
if
required)
have
nominal
impedances
of
50
Ω
across
the
frequency
bands
in
.
•
All
tests
(except
isolation
/
correlation
coefficient)
—
test
the
main
or

antenna
with

‐
nated.
•
Any
metallic
part
of
the
antenna
system
that
is
exposed
to
the
outside
environment
needs
to
meet
the
electrostatic
discharge
tests
per
IEC61000
‐
4
‐
2
(conducted
discharge
+8kV).
•
The
functional
requirements
of
the
antenna
system
are
tested
and
verified
while
the
MiniCard
antenna
is
integrated
in
the
host
device.
Note: Additional testing, including active performance tests,
mechanical, and accelerated life tests can be discussed with Sierra
Wireless’ engineering services. Contact your Sierra Wireless repre-
sentative for assistance.
