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.
Rohde&Schwarz milestones in digital testing
• 1990: CMTA94 – the first test set for GSM transmitter and receiver testing
• 1991: CRTS02/04 – signalling tester for GSM mobile and base stations
• 1992: FTA – sole supplier of the GSM900 system simulator for type-approval
testing of mobiles
• 1993: TA – sole supplier of GSM900 interim type-approval system,
upgradable to GSM1800
• 1996: CRTP/C02 – approved as stand-alone tester for type approval
of phase II GSM900/1800 mobiles
• 1997: supplier of the first type-approval system for GSM1900

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
• Go/nogo tests and comprehensive testing of mobiles
• Powerful signalling capabilities
• Short measurement time
ensuring high throughput
• High measurement accuracy
• Simple interactive operation
•No specialized GSM
knowledge required
• Service mode for exact fault
location
•Autotest – complete mobile
testing at a keystroke
•Very fast remote control
operation
• Compact and lightweight
• Excellent price/performance
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

A sophisticated product from the market leader
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.
