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
• 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

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.
