Shown here, the frontpanel for desktop use. For more than 60 years Rohde&Schwarz has always been at the forefront of mobile radio technology. We continue this tradition of RF test and measurement with Universal Radio Communication Tester CMU200. The CMU200 is a third generation platform design, that offers true scalable multimode functionality. CMU200 reflects the long-standing expertise Rohde&Schwarz has gained in the world of mobile radio. In recent years, the company has helped to launch over- whelmingly successful mobile radio sys- tems. Rohde&Schwarz is a preferred supplier to many of the leading mobile equipment manufacturers and is the market leader for mobile radio test sets. The CMU200 is part of a complete range of mobile radio test equipment, encom- passing everything from conformance test systems, to system simulators, turn- key functional board test / final test sys- tems and simple sales counter Go/NoGo testers. The base unit with its standard-independ- ent module test provides many general purpose measurement facilities for the development of all kinds of standards within its wide and continuous frequency range. If extended by the relevant options, the CMU200 offers the hardware and software necessary to handle your 3G, “2.5G“ and previous generation test- ing applications including analog. Low cost of ownership Selecting the CMU 200 is a decision for the future and results in a total cost of ownership which is sure to be among the lowest due to the following factors: ◆ Completely modular design of hard- ware and software components avoids unnecessary investments right from the start just because there is a possibility of a feature being needed sometime in the future. You only pay for what you need ◆ Should an extension become nec- essary because your needs widen af- ter some time – the modularity of the CMU200 concept will cater for that. Many extensions to the unit may be installed onsite. You only pay for it when you need it ◆ The concept allows two complete channels (RF, signalling and evalua- tion) to be installed in one CMU200 unit ◆ Maximum production output in a compact 4-rackunit-height package with minimum power dissipation al- lows compact production space lay- out ◆ With the CMU200 user interface even less experienced users will intuitively get it right without the need for ex- tensive training ◆ A new remote interface syntax re- flects the inherent modularity of this real multimode tester Testing the 3rd generation Applications • RF development • Module design • Module test in production • Adjustment of mobiles • Final test in production • Functional test • Feature test • High-end service • Quality inspections • Basis for test systems • Base station simulation 4 Universal Radio Communication Tester CMU200 the ProbeDSP™ technology em- ployed. Examples of parallel operation are measurements of BER and simul- taneous Phase/Frequency error, EVM, Magnitude Error and audio or the various spectrum measurements. ◆ Innovative remote processing The novel secondary addressing mode can address similar functions of each of the CMU200 subsystems (different mobile radio standard) in an almost identical way. Using this type of ad- dressing, new remote test sequences can be programmed by a simple cut and paste operation followed by edit- ing specific commands to adapt the control program to the new applica- tion. Secondary addressing is fully SCPI-compliant which means that a subsystem address, for example “WCDMA-FDD“, can be replaced by a string denoting a different subsystem, another mobile radio standard. Usability The CMU200 key strengths The Radio Communication Tester CMU200 brings premium cost effective- ness through a variety of features, with extremely fast measurement speed and very high accuracy being the two most important ones. In addition, the second- ary remote addressing of the unit's mod- ular architecture makes for intelligent and autonomous processing of complete measurement tasks and fast control pro- gram design. Greatest accuracy In a production environment the unit’s high accuracy allows DUTs (Device under Test) to be trimmed for maximum battery life- time without compromising quality. In the lab, CMU200 enables the development engineer to partly replace conventional, dedicated premium-quality instruments and save desktop space at the same time. High precision measurement correction over the whole frequency and dynamic range as well as compensation for temper- ature effects in real time are critical factors for achieving the CMU200’s excellent accu- racy. The globally standardized Rohde&Schwarz calibration system can check CMU 200 accuracy in a service center close to you or, volume permitting, on your site. A world- wide network of these standardized auto- matic calibration systems has been imple- mented in our service centers. Highly accu- rate and repeatable calibration can be per- formed wherever you are. Your local Rohde&Schwarz representative offers cus- tomized service contracts for the unit. For large scale users of CMU200 a compact level verification system is available, in addition. Greatest speed The high processing speed is due to exten- sive use of ProbeDSP™ technology, parallel measurements and innovative remote command processing. ◆ ProbeDSP™ technology The modular architecture relies on decentralized ProbeDSP™ processing coordinated by a powerful central processor. Like an oscilloscope probe, DSPs dedicated to a specific local da- ta acquisition and evaluation work- load help to keep subsystem perform- ance at an uncompromising maximum even if additional modules are fitted to the CMU200 mainframe. ◆ Parallel measurements Several RX and TX measurements can be performed in parallel. This is achieved by the fast response of the CMU200's modular hardware as well as the high overall processing power of the unit and the avoidance of bot- tlenecks by dedicated operation of Thanks to the high resolution of the extremely bright high-contrast TFT display even the finest details can be displayed Direct branching to all asso- ciated menus makes for a uniquely flat menu structure Universal Radio Communication Tester CMU200 5Universal Radio Communication Tester CMU200 5 Greatest reliability CMU200 employs an ultra effective heat management between housings and indi- vidual components as well as between heat sinks and the air flow. Together with the independent cooling cycles for differ- ent modules, this adds up to an optimized cooling system. The base unit The base unit without any options installed can be used for testing general parameters of 1st, 2nd or 3rd generation mobile phones. The CMU200 base unit is the ideal solution for tasks at module level, i.e. at the early production stages of all cellular standards. Constituent parts of the CMU200 base unit are the RF generator and RF analyzer which are complemented by a versatile network-independent time domain menu and a comprehensive spectrum analyzer. As an example power versus time meas- urement is shown above. By combining graphical and numerical over- view menus the optimal view can be cho- sen when the CMU200 is in manual mode. The menu structure of the CMU200 is very flat and uses context-sensitive selec- tion, entry and configuration pop-up menus. Advanced operational ergonomics have been incorporated into a most compact and lightweight, 4 rack units high pack- age.

Time to Market The key to commercial success resides in the time required to get a new product to market in large volume. The crucial point is the fast transition from product devel- opment stage to mass production. The TS7100 Cellular Phone Production Test Platform featuring the CMU200 meets this challenge. TS7100 Description in Brief The stringent requirements in the produc- tion environment of mobile phones make it necessary to implement new strategies in the specification of test systems. The test system architecture is based on two CMU200s to provide the optimum throughput solution. The TSVP (Test System Versatile Platform) test platform is based on the industry standard Compact PCI/PXI. This new type of bus is up to 6 times faster than previ- ous industry bus standards. The TSVP´s CompactPCI frame is 100% compatible to the industry standard but features 14 up to 31 slots. It comprises a state-of-the-art controller PC, digital multimeter and selectable switching and test modules. For each DUT the test hardware for switching and stimulus functions is implemented as a dedicated set of modules. The TSVP takes up all modules used for control and additional measurements. Off-the-shelf CompactPCI/PXI modules can be added. Up to 4 sets of modules for testing DUTs can be inserted. The soft- ware can thus simultaneously use the resources of the parallel instrumentation to maximize speed in highly automated production. We can offer optimal config- ured test systems customized to your pro- duction environment. Test Executive & Generic Test Software Library Features The parallel hardware is fully supported by TestStand, the industry-wide test exec- utive from National Instruments. A user- friendly connection to the available device drivers has been created to pro- vide faster use of the test executive. This connection is established by the Generic Test Software Library (GTSL). At the same time the toolkit concept provides ready- to-run test cases, which can be custom- ized by the user as required.

PSU and switch matrix fit- ted to the rear of rack 8 Universal Radio Communication Tester CMU200 GSM today Since its introduction in the early nine- ties, the GSM system has won accept- ance and undergone an evolution that no one could have foreseen. The applications of the GSM system are numerous and are currently: ◆ GSM400 ◆ GSM850 ◆ GSM900 including – P-GSM (primary GSM) – E-GSM (extended GSM) – R-GSM (railway GSM) ◆ GSM1800 (DCS) ◆ GSM1900 (PCS) Whether the application is in production, service or development, the flexible con- cept of the CMU 200 from basic RF signal generation, frequency, power and spec- trum analyzer measurements for align- ment of modules in production or devel- opment applications, to an instrument with full GSM-specific signalling in any of the above-mentioned bands, as well as module tests on frequencies anywhere in the range from 10 MHz to 2700 MHz. Signalling mode The CMU200 simulates a GSM base sta- tion RF interface with the signalling flexi- bility necessary to test the behaviour of the mobile under the influence of differ- ent signalling parameters. These parame- ters are normally set by the network oper- ator but can be reproduced by the CMU200 for test purposes. The unit sup- ports the latest fast location update and direct paging features. Reduced signalling synchro- nized mode The CMU200 provides the same function- ality as in the Signalling mode, but dis- cards any signalling reaction from the mobile connected. This mode of opera- tion enables both testing of modules that only have layer 1 operation and very fast RF testing in production environments. It can also skip the location update proce- dure in order to save time. Non-signalling mode This mode serves for generating a signal with GSM-specific midambles and modu- lation in the entire frequency range from 10 MHz to 2.7 GHz. The analyzer offers the same flexibility for GSM-specific transmitter measurements such as ◆ modulation analysis ◆ average and peak burst power ◆ power versus time, power versus slot, power versus frame ◆ spectrum due to switching /modula- tion GSM development As an all-round tool for GSM development engineers, the CMU 200 is an unsur- passed solution. The RF interface pro- vides four input and output connectors offering a wide range of signal levels for generation and analysis of RF signals. Input only, as well as combined input/ output connectors, can analyze mobiles or modules with a sensitivity down to −80 dBm and up to +47 dBm for the power meter. RF signals can be generated with levels from −130 dBm up to +13 dBm, depending on the selected connector. All measurement tolerances are set by default according to the GSM 11.10 and GSM 05.05 recommendations but may of course be altered to suit individual needs. Production of mobile phones Production is a process that calls for cost effectiveness. The CMU200 concept is optimized for IEC/IEEE-bus speed, mea- surement accuracy and reproducibility as well as cost of ownership. Thanks to the multitasking feature and parallel meas- urements, previously unobtainable test times can be achieved. The ability to process BER data and per- form transmitter measurements at the same time, allows phase / frequency error, power versus time and average power (PCL accuracy) to be measured during the time-consuming receiver test. The accuracy and reproducibility ensure correct and steady measurement results and thus contribute to the quality and reliability of the end product. GSM Evolution – 2.5G The amount of data transfer in GSM net- works is growing rapidly. Multislot appli- cations such as HSCSD or GPRS together with the innovative 8 PSK modulation scheme EDGE are needed to cater for the evolving data traffic. The CMU200 plat- form is not only able to meet today’s standards and systems but is also designed for the needs of tomorrow. Multislot In the future, mobile phones will be able to use several timeslots simultaneously for data transmission and reception to further increase the data rate. The simultaneous transmission and reception of several timeslots (multislot) is the technological Ready for today‘s networks … Universal Radio Communication Tester CMU200 9 GSM-specific non-signalling test provides gen- eration and analy- sis of RF signals for testing of RX/ TX modules or mobiles in service mode challenge for circuit-switched and packet-switched applications. The following extensions of the GSM single-slot measurements enable maximum flexibility in develop- ment, and, due to minimum meas- urement times, maximum through- put in production. ◆ Individual levels for all time- slots used in the down link (DL). The CMU generates up to eight timeslots per frame in the down link; each timeslot can be assigned a separate level. The excellent level stabil- ity of the CMU200 generators is not impaired by multislot transmission using different levels, and allows the most ac- curate measurements of re- ceiver sensitivity (BER/DBLER). ◆ Transmitter and receiver meas- urements are possible on eve- ry timeslot used. The new mul- tislot concept allows inde- pendent measurements on any timeslot (TS 0-7) and thus covers the current and future multislot combinations with- out restrictions. ◆ Power-versus-time measure- ment (graphical display) for up to four timeslots in the UL. The templates of this application are evaluated independently for each timeslot - in line with standards and according to recommendations. Both GMSK- and 8PSK-modulated signals are recognized, and the templates of the relevant timeslot are set in realtime. Multislot measurements are required for HSCSD and ECSD tech- nologies as well as for GPRS and EGPRS. In the GSM non signalling func- tion groups the possibility to switch between GMSK and 8PSK (EDGE) is already implemented. Thus EDGE bursts as shown here can easily be ana- lyzed The overview menu provides fast comprehen- sive information on the mobile’s RF performance. The hotkeys at the bottom of the screen gi
