Rohde & Schwarz
presents multistandard test
solution for RF and audio
tests on Bluetooth
®
modules
The modules used in Internet of
Things (IoT) applications often
combine Bluetooth® with other
wireless
interface
technologies.
The R&S CMW500 wideband radio
communication tester is the only
test platform on the market to offer a
one-instrument solution for testing all
cellular and non-cellular standards
and Bluetooth. Rohde & Schwarzhas
now expanded it leading test platform
to include Bluetooth audio tests for
manufacturers of Bluetooth headsets
and audio car kits.
Today, Bluetooth modules are used in
mobile, automotive, smart home and
other IoT applications. Accordingly,
manufacturers
and
integration
specialists have higher testing
requirements. Rohde & Schwarz helps
them to optimize test performance,
minimize test times and thus save
considerable costs. TheR&SCMW500
wideband
radio
communication
tester is the only testing solution that
combines all 38 RF signaling tests
defined by the Bluetooth SIG together
with other cellular technologies such
as LTE, LTE-Advanced and WCDMA
as well as non-cellular technologies
such as WLAN and GNSS. The
Bluetooth Special Interest Group
(SIG) has qualified the solution for RF
measurements.
RF signaling tests and fast spectrum
measurements
Developers can use the R&S
CMW500 to perform extensive tests
on their Bluetooth products and
optimize their design before taking it to
a Bluetooth Qualification Test Facility.
The test platform offers unparalleld
flexibility since the parametric test
concept allows developers to set all
the parameters themselves. Thanks
to the easy-to-use R&S CMWrun
sequencer software tool, they can also
use the compact solution to perform
automated prequalification tests for
Bluetooth Basic Rate, Enhanced Data
Rate and Bluetooth Low Energy in line
with Bluetooth core specifications for
versions 1.2, 2.0, 2.1, 3.0+HS, 4.0,
4.1, 4.2.
The extremely fast R&S CMW500
greatly benefits developers, e.g. when
performing the complex spectrum
measurements that are part of the
Bluetooth qualification tests. The
R&S CMW500 delivers the first test
results in less than one second,
which simplifies optimization tasks.
The solution is also ideal for general
integration and coexistence tests, for
example, to check whether WLAN
and Bluetooth transmitters in certain
frequency bands interfere with each
other.
New R&S CMW-KS602 option for
Bluetooth audio tests
Thosewho do not have their hands free
when using a computer or driving rely
on Bluetooth headsets and Bluetooth
hands-free car kits to make telephone
calls. Manufacturers of headsets or
hands-free car kits can now ensure
the quality of their products by using
the R&S CMW500 to test the audio
properties of their products as well
as to perform RF signaling tests. The
Rohde & Schwarz test platform can
be used in the development phase to
optimize products and in production to
verify audio characteristics.
When establishing the Bluetooth
connection,
the
flexible
R&S
CMW500 can operate as master
or slave. It supports the hands-free
audio gateway mode, authentication
when pairing Bluetooth devices with
headsets, etc. and the volume control
function on the microphones and
headsets. it supports various voice
codecs, including CVSD and mSBC.
R&S CMW platform: the right solution
for all M2M/IoT requirements
For users who only performBluetooth®
and WLAN non-cellular integrations
tasks, the R&S CMW270 wireless
connectivity tester offers a cost-
effective solution. The R&S CMW270
was also qualified by the Bluetooth
SIG for RF measurements. The R&S
CMW290 functional tester supports
all common cellular and non-cellular
mobile communications standards.
Wireless module integrators require
extensive functional tests for hardware
and applications. The R&S CMW290
offers all essential measurements and
an excellent price/performance ratio.
Rohde & Schwarz will demonstrate
its R&S CMW platform for Bluetooth
tests at booth C40, hall 6 at Mobile
World Congress in Barcelona. The
new R&S CMW-KS602 option for
Bluetooth audio tests will be available
fromRohde & Schwarz in March 2016.
