Staying in the lead ...

The Digital Radiocommunication Test­ers CMD have evolved from GSM900
mobile station testers to a fully
equipped test and measurement solu­tion for mobiles and handhelds for all
GSM-based systems as well as DECT.

.... thanks to

continuous innovation

The CMD is the industry standard in
mobile radio testing and defines the
levels that others are judged by. With
extremely high market acceptance
worldwide, the family will stay in the
lead thanks to constant innovation, a
well-chosen modularity through differ­ent models and optional extension.

The CMD addresses all aspects of test
and measurement applications from
production and service to develop­ment and quality assurance.

Manual operation philosophy

Research and development engineers
have found the CMD‘s large clear LC
display and user interface with logi­cally structured menus unsurpassed
when measuring RF parameters. This
is true both in the manual test mode
and in the flexible module test with sys­tem-specific signal generator and
burst analyzer. During call setup the
network and system-specific signalling
parameters allow the R&D engineers
to control the influence of signalling
parameters on the mobile´s behaviour
in the network.

quality assurancedevelopment

User-definable autotest

The user-friendly display and opera­tion of the CMD is a main requirement
when testing manually, but for auto­mated testing, the engineer wants a
quick and easy way to a ready-made
autotest or if he has to create his own
test script for the specific task to be
performed. The CMD family of testers
offers different ways of creating such
autotests and test scripts, depending
on the CMD model and the test
requirements.

... meeting the challenges
of modern communications

ratio

The mobile communications market is
growing beyond anybody’s imagina­tion and the need for testing has there­fore become equally demanding.

As the leading manufacturer of type-ap­proval test systems for several world­wide digital wireless standards,
Rohde&Schwarz has succeeded in
combining these standards in one fam­ily of instruments, aimed at users in pro­duction, service and development.

This data sheet covers the testers for
GSM mobiles as well as for DECT fixed
and portable parts (FP and PP).

The CMD65 – our top model of mobile
testers – combines a number of well­known key features of the CMD family.
The four most common digital systems
in one instrument, ready at a keystroke,
provide the user with ultimate flexibility.

networks and their configuration
menus, measurements and tests as well
as autotest function.

The CMD53 and the CMD55 offer full
GSM functionality including the hando­ver between GSM bands.

To start out with a single standard, the
Testers CMD50, CMD52 (GSM900)
and CMD60 for DECT applications are
the right choice.

Adding another standard later is no
problem, as the clearly laid-out up­grade path depicted on the back cover
fold-out will demonstrate.

From the main menu, the CMD65 offers
very easy access for up to four digital

production service

Fast IEEE-bus

In a production line, there are two
main factors that contribute to high
throughput and product quality: IEEE­bus speed and measurement repeata­bility. The high speed is obtained by
parallel measurements and the possi­bility to issue multiple commands in a
single IEEE string. With combined
measurements and measurements like
RF peak power which takes only milli­seconds, time-consuming power level
adjustments where multiple measure­ments are required are completed in
seconds. The level of measurement

repeatability offered ensures the high­est possible quality of the end product
leaving the factory.

Covering any need for test modes

Service and repair of digital mobiles
and cordless phones call for a variety of
tests, ranging from simple go/nogo tests
to complete factory-like production tests
and calibration of the phone. The CMD
range offers cost-effective solutions for
manual testing, stand-alone autotest, as
well as remote RS-232-C operation solu­tions covering any need for testing.
Every CMD comes, of course, with the

same large display and user interface
for manual test of phones and/or mod­ules and RS-232-C interface for remote
operation.

Base station survey measurements

These are often performed on real base
stations or by using analog signal gener­ators with power amplifiers. The CMD is
able to simulate any GSM base station
BCCH, including parameters like MCC,
MNC, NCC, BA list, DTX and DRX infor­mation. These and the "cell barred" fea­ture enable close-to-life conditions with­out having to use a real BTS.

Tailored to your application

Through careful design of models and
options, Rohde&Schwarz has devised
a way to ensure you only pay for what
you need. Nearly all the options for
the models offered (see front cover
fold-out) are retrofittable.

The well-defined upgrade path allows
to expand the scope of a new CMD
when you need it (see back cover fold­out). Should you already own one –
even first generation CMDs are taken
care of.

Interface description

CMD 60/65 transmitter part

In a very busy DECT environment,
most DECT frequencies may be in use
for communication and therefore influ­ence the measurement in production
and development. Besides the chan­nels 0 to 9 the CMD enables the use of
an extended frequency range for test­ing. The channels −3, −2, −1 and 10,
11, 12 are outside the normal DECT
specification and therefore free for
testing. Up to 35 channels are avail­able with options CMD-U61 and
CMD-K61 (channels +12 to −22).

The wide amplitude range of the RF
level provides a comfortable compen­sation for attenuation in external cou­pling devices.

The CMD enables the use of up to 6
TDMA slots for rapid BER measure­ments for PP test (2 slots for FP test). A
very short measuring time for produc­tion can be achieved with the use of
more than one timeslot for BER mea­surements if supported by the unit
under test.

The modulation is GFSK with B x T =

0.5 according to DECT specifications.
In addition, constant envelope, signals
with or without modulation or DECT
bursts with various bit patterns for
module testing are possible. These bit
patterns can easily be recognized
while testing receiver and demodula­tor modules.

CMD 60/65 receiver part

It is similar to the transmitter part above.
There are 10 DECT frequencies, 0 to 9.
Additionally, the 6 extended DECT fre­quencies −3, −2, −1 and +10, 11, 12 in
half DECT channel spacing are pro-

vided. Up to 35 channels are available
with the options CMD-U61 and CMD­K61 (channels +12 to −22).

The modular concept of the CMD also
allows the Latin American frequency
extension to be added (see CMD-K61
and CMD-U61 in the options section).

The sensitivity of the CMD60 ensures
valid measurement results even with
compensation for attenuation in exter­nal coupling devices.

There are two independent receive
paths: For DECT signalling and BER, a
signalling path is provided. For TX
tests, the CMD60 provides a measure­ment path. The signals from the FM
and envelope detector are taken to
external connectors and post-pro­cessed for power ramp and modula­tion measurements. The FM and enve­lope detector output permits monitor­ing of the DUT transmit signal.

Benefits in ...

... production

• The CMD60/65 is remote-con­trollable via RS-232-C or IEC/
IEEE-bus interface using the
SCPI-compatible commands. In
the remote-control mode, the
CMD is designed for fast speed
to yield high throughputs in pro­duction

• High production output versus
low investment for test equip­ment

• Comprehensive flexible autotest
capabilities make the CMD60/
65 a one-box DECT solution

RF in/out configuration

Transmitter and receiver are con­nected to a bidirectional N connector
(RF in/out). All specifications men­tioned are valid for this connector.
Moreover, there is a high-level output
for the CMD transmitter and also a
sensitive input for the CMD receiver on
the front panel. These connectors
together with an external power split­ter/combiner can be used to shift the
level range of the N connector (for
details on differences between the
CMD60 and CMD65 see specifica­tions).

Demodulation interface

The CMD 60/65 provides a linear
analog FM demodulator output (DC
coupled) and a logarithmic analog RF
envelope demodulator output.

Wideband in/out

The secondary wideband input/output
is at the rear panel. The input signal

• Comprehensive in-depth mea­surements of specifications via a
convenient manual user inter­face

• A lot of complex test setups re­quired with conventional equip­ment become redundant thanks
to this special DECT tester

• Automated regression tests and
stress tests

• The tester supplies a large
number of DECT-specific sig­nals for the control of the mod­ule under test

from the front connector is available at
this connector with an attenuation of
18 dB. It can be monitored with a spec­trum analyzer for spurious measure­ments. Furthermore, this connector can
be utilized to introduce an interferer into
the RF connection without reconnecting
the test setup for the in-channel tests. This
input/output can be used from
100 MHz to 2.5 GHz.

Audio part

In addition to the DECT RF interface on
the CMD60 front panel, there is an ana­log DECT speech interface for speaker
and appropriate microphone on the
rear panel (analog ADPCM interface).
Alternatively, it can be internally con­nected to the AF measurement port.

... servicing

• Rapid go/nogo results using the
autorun function

• Relaxed manual operation due
to a large bright LCD in con­junction with an extremely sim­ple user interface (requires no
DECT-specific knowledge) strict­ly separated from the expert us­er interface for configurations

• Integrated tools such as a scope
display for power versus time
and FM demodulation versus
time ease troubleshooting

Trigger

DECT measurements are alternatively
triggered under the following condi­tions:
– RF rising slope
– External trigger event
– Internal trigger, time reference is bit

P0 (standard)

Time synchronization

The CMD60 provides DECT-specific
timing signals (frame clock, RS485)
which can be routed to other CMDs if
the CMD is the master. If the CMD is
declared slave, it will synchronize to
this signal. This way several PPs, e.g.
on a production line, can be tested at
several CMDs in parallel without any
mutual interference.

Additional DECT-specific signals

1152 kHz bit clock output, alternatively
multiples: 3,456, 6,912 and
13,824 MHz and fractions:
576, 288, 144 kHz.
