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 over­whelmingly successful mobile radio sys­tems.
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, encom­passing everything from conformance test systems, to system simulators, turn­key functional board test / final test sys­tems and simple sales counter Go/NoGo testers.
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 af­ter 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 evalua­tion) to be installed in one CMU200 unit
Maximum production output in a
compact 4-rackunit-height package with minimum power dissipation al­lows compact production space lay­out
With the CMU200 user interface even
less experienced users will intuitively get it right without the need for ex­tensive training
A new remote interface syntax re-
flects the inherent modularity of this real multimode tester
The base unit with its standard-independ­ent 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 test­ing applications including analog.

Usability
The CMU200 key strengths
The Radio Communication Tester CMU200 brings premium cost effective­ness through a variety of features, with extremely fast measurement speed and very high accuracy being the two most important ones. In addition, the second­ary remote addressing of the unit's mod­ular architecture makes for intelligent and autonomous processing of complete measurement tasks and fast control pro­gram design.
Greatest accuracy
In a production environment the unit’s high accuracy allows DUTs (Device under Test) to be trimmed for maximum battery life­time 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 temper­ature effects in real time are critical factors for achieving the CMU200’s excellent accu­racy. 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 world­wide network of these standardized auto­matic calibration systems has been imple­mented in our service centers. Highly accu­rate and repeatable calibration can be per­formed wherever you are. Your local Rohde&Schwarz representative offers cus­tomized service contracts for the unit. For large scale users of CMU200 a compact level verification system is available,

Greatest speed
The high processing speed is due to exten­sive use of ProbeDSP™ 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 da­ta acquisition and evaluation work­load help to keep subsystem perform­ance 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 bot­tlenecks by dedicated operation of
technology, parallel
the ProbeDSP™ technology em­ployed. Examples of parallel operation are measurements of BER and simul­taneous 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 ad­dressing, new remote test sequences can be programmed by a simple cut and paste operation followed by edit­ing specific commands to adapt the control program to the new applica­tion. 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.

Key advantages of the CMU200
Speed
Greatest reliability
CMU200 employs an ultra effective heat management between housings and indi­vidual components as well as between heat sinks and the air flow. Together with the independent cooling cycles for differ­ent 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.
For increased speed, not required measurements can be switched off to free resources for the measurements you want to focus on
Measurements are con­figured by pressing the softkey marked with the yellow triangle two times
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 meas­urement is shown above.
By combining graphical and numerical over­view menus the optimal view can be cho­sen when the CMU200 is in manual mode.
The menu structure of the CMU200 is very flat and uses context-sensitive selec­tion, entry and configuration pop-up menus.

GSM today
Since its introduction in the early nine­ties, the GSM system has won accept­ance 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 con­cept of the CMU 200 from basic RF signal generation, frequency, power and spec­trum analyzer measurements for align­ment of modules in production or devel­opment 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 sta­tion RF interface with the signalling flexi­bility necessary to test the behaviour of the mobile under the influence of differ­ent signalling parameters. These parame­ters are normally set by the network oper­ator but can be reproduced by the CMU200 for test purposes. The unit sup­ports the latest fast location update and direct paging features.
8 Universal Radio Communication Tester CMU200
Reduced signalling synchro­nized mode
The CMU200 provides the same function­ality as in the Signalling mode, but dis­cards any signalling reaction from the mobile connected. This mode of opera­tion 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 proce­dure in order to save time.
Non-signalling mode
This mode serves for generating a signal with GSM-specific midambles and modu­lation 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

GSM development
As an all-round tool for GSM development engineers, the CMU 200 is an unsur­passed solution. The RF interface pro­vides 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 dBm and up to +47 dBm for the power meter. RF signals can be generated with levels from 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, mea­surement accuracy and reproducibility as well as cost of ownership. Thanks to the multitasking feature and parallel meas­urements, previously unobtainable test times can be achieved.
The ability to process BER data and per­form 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 net­works is growing rapidly. Multislot appli­cations 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 plat­form 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
challenge for circuit-switched and packet-switched applications. The following extensions of the GSM single-slot measurements enable maximum flexibility in develop­ment, and, due to minimum meas­urement times, maximum through­put 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 stabil­ity of the CMU200 generators is not impaired by multislot transmission using different levels, and allows the most ac­curate measurements of re­ceiver sensitivity (BER/DBLER).
Transmitter and receiver meas-
urements are possible on eve­ry timeslot used. The new mul­tislot concept allows inde­pendent measurements on any timeslot (TS 0-7) and thus covers the current and future multislot combinations with­out 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 tech­nologies as well as for GPRS and EGPRS.

Universal Radio Communication Tester CMU200 9
8PSK modulation – EDGE
8PSK is besides multislot a further step towards increasing the mobile radio data rate. By using the available GSM frame structure, the gross data rate is three times that obtained with GMSK. The CMU200 can already perform 8PSK on GSM bursts and analyze them thanks to advanced measurement applications. Error vector magnitude and magnitude error have been added to the range of modulation measurements. New tem­plates for power-versus-time measure­ments ensure compliance with the speci­fications, as do the modified tolerances for spectrum measurements. 8PSK will transform HSCSD technologies into ECSD and GPRS into EGPRS. As with all meas­urements provided by the CMU200, spe­cial attention has been given to achieving maximum measurement accuracy and speed for EDGE too.
GPRS/EGPRS
Thanks to the new, future-oriented method of packet data transmission, the radio resources of existing GSM mobile radio networks can be utilized efficiently for data services. As with circuit-switched services, GPRS will also use a combina-
In the 8PSK mode the modulation analysis is subdivided. The error vector magnitude, the magnitude error and the phase error can be displayed both numerical as shown above, or graphical.
tion of several timeslots (multislots) and higher-level modulation in the form of 8PSK (EGPRS) to push up the data rate. The introduction of packet-oriented trans­mission and the associated temporary assignment of radio resources require new test concepts. The CMU 200 pro­vides the following test modes:
ETSI Test Mode A: In test mode A, the
mobile is induced to continuously transmit the associated UL timeslots. The CMU 200 can carry out all TX
power ramp measurement of up to four adjacent timeslots simultaneous­ly, or modulation and spectrum meas­urements.
ETSI Test Mode B: Test mode B cre-
ates a loop back in the telephone so that the mobile retransmits data blocks received from the CMU 200. In addition to the measurments availa­ble in the ETSI test mode A, test mode B enables bit and block error rate measurements (BER/DBLER).

Reduced signalling synchro­nized mode
Extremely fast adjustment and testing of RF parameters during GPRS mobile phone production is ensured by deacti­vating the GPRS protocol stack. Without using the higher protocol layer (RLC/MAC layer), the CMU 200 synchronizes the mobile (camping), the data channel (PDCH) is then set up directly.
The GPRS and EGPRS data coders are already available to determine Bit Error Rates (BER) and Data Block Error Rates (DBLER).

TDMA in CMU200
The need for higher data rates is the trend in our information-oriented society in the new millennium. The enhancement of mobile phones takes this need into account on the way to the next genera­tion of wireless communication. Need to test these future improvements?
CMU200 does it all. The TDMA part takes care of your requirements to cope with this fast progressing mobile technology. The CMU200 concept with its multistand­ard platform architecture provides for fur­ther extensions such as Bluetooth and cdma2000.
TDMA
The wide acceptance of TDMA (IS-136) is based on a very flexible and powerful technology as well as on its compatibility with AMPS, which is widespread and one of the major wireless communication standards. Derived from analog AMPS, the TDMA standard is now ready for a step-by-step evolution into the third gen­eration of mobile technology. This fact shows the need for a test instrument that is flexible enough to cover all future needs as well as the current standards.
For TDMA (IS-136) signalling functional­ity, the CMU200 requires the versatile sig­nalling unit (CMU-B21) as well as the software option CMU-K27 for the cellular band or CMU-K28 for the PCS band.
Due to the highly user-friendly menu con­cept, the CMU200 provides quick access to all measurements desired, optimizing handling and consequently efficiency.
Signalling mode
The CMU200 simulates a TDMA base­station RF interface including the signal­ling protocol so that a mobile can be tested with regard to different signalling parameters. All necessary network and base-station parameters can be set, such as control and traffic channel configura­tion, neighbouring channels setup etc. You can also generate a MAHO report.
Non-signalling mode
The non-signalling mode is for generating and analyzing TDMA (IS-136) signals within the frequency range from 10 MHz to 2.7 GHz. CMU200 provides TDMA-spe­cific measurements such as:
Power
Modulation
Spectrum
Power versus time
BER
TDMA (IS-136) development
With its great versatility the CMU 200 is the most suitable tool for the develop­ment of mobile phones. Four configurable RF connectors are provided to enable flexible signal generation and analysis. The power meter can evaluate signals within a range from 47 dBm, whereas the generator outputs signals from
130 dBm to +13 dBm. The clearly struc-
tured and user-friendly menu design together with the clear-cut screen layout provides quick access to all features and ensures trouble-free monitoring of the device under test.
80 dBm to+
Quality assurance
Due to its high measurement repeat­ability and accuracy, the CMU200 is the right choice to ensure a consistently high quality standard from production. TDMA­specific measurements such as BER, Error Vector Magnitude (EVM) and EVM10, where only the first 10 symbols are taken into account, provide an excellent test platform to guarantee the production of high-quality devices.
Production of mobile phones
The production of mobile phones requires time-efficient and cost-effective means that ensure both high throughput and state-of-the-art accuracy. Thanks to the unique IEC/IEEE-bus concept of the CMU200, these two goals can be easily achieved in your production line. The intelligent handling of the received GPIB commands optimizes the measurement speed for all TDMA-specific measure­ments. In practice, this will mean drasti­cally enhanced test time and test yield.
Acoustic Measurements
The newly implemented ACELP speech coder is able to encode and decode real audio signals and allows you to use the CMU200 also in real acoustic measure­ment applications. Equivalent to the GSM implementation of the CMU200 the TDMA speech coder provides analog inputs and outputs and a connector for an external handset. The speech coder requires the hardware option CMU-B52 and can also be combined with the inter­nal Audio Analyzer/Generator option CMU-B41.

TDMA in CMU200
Handoffs
Handoffs are part of the IS-136 specifica­tion. Handoffs between PCS and cellular bands as well as from and to AMPS are defined and have to be tested. CMU200 supports handoffs from IS-136 800 MHz to 1900 MHz (inter-band handoff) and vice versa. Handoffs from 1900 MHz or 800 MHz to AMPS and back are also pos­sible (inter-mode handoff) with CMU200.
Switching standards
The flexibility of CMU200 makes for quick and simple switching between two differ­ent standards. This is very important for IS-136, which is a dual-mode standard containing a digital (TDMA) and an ana­log mode (AMPS). The handoff between TDMA and AMPS can be achieved by sim­ply pressing a button. This results in a very versatile test concept to improve the flexibility and throughput of your produc­tion line.
In the modulation overview menu, error vector magnitude (EVM), phase error and magnitude error are measured simultaneously and displayed in a numerical table It is possible to choose either EVM, where the whole burst is considered, or EVM10, where only the first ten symbols are taken into account

AMPS in CMU200
AMPS overview
Analog AMPS (advanced mobile phone system) is a standard system for analog cellular telephone service in the United States and is also used in other countries. It is based on the frequency spectrum allocation for cellular service by the Fed­eral Communications Commission (FCC) in 1970. Introduced by AT&T in 1983, AMPS became the most widely deployed cellular system in the United States.
AMPS options
Although AMPS is a 1st generation ana­log standard, a great demand for mobile radio testers covering this standard will continue to exist in the future. Especially in the United States, dual-mode CDMA/ AMPS and TDMA/AMPS phones are very common. By combining the digital stand­ards with analog AMPS, the network operators offer their customers the advantages of the digital standards and ensure nearly 100% coverage in North America. As a consequence, Rohde& Schwarz is extending the range of CMU200 options by introducing analog AMPS in addition to the digital standards TDMA and CDMA. These options add analog AMPS functionality to the CMU200 base unit:
CMU-B21 (versatile link handler)
CMU-B41 (audio generator/analyzer)
CMU-K29 (AMPS test software)
The hardware options CMU-B21 (versatile link handler) and CMU-B41 (audio gener­ator/analyzer) are suited for other stand­ards as well.
AMPS measurements and features
As for other standards, there are two cat­egories of AMPS measurements:
Transmitter tests for assessing the
transmit part of a mobile
Receiver tests for assessing the
receive part of a mobile
AF Level Search routine
Sensitivity Search routine
The AF Level Search routine in the TX test menu allows the user to set the desired frequency deviation of the mobile trans­mitter at a keystroke, the level of the CMU200 modulation generator is auto­matically corrected.
The Sensitivity Search routine in the RX test menu automatically searches the receiver input level at which a selectable SINAD of the demodulated signal can still be attained. The following list provides an overview of the most important tests implemented in option CMU-K29.

cdmaOne in CMU200
CDMA overview
Code division multiple access (CDMA) – once a radically new concept in wireless communication – has meanwhile become a well established standard in the world of mobile communication. CDMA has proven its advantages and capabilities and has gained widespread international acceptance.
Instead of using frequencies or timeslots as traditional technologies like TDMA and AMPS do, CDMA uses mathematical codes to transmit and distinguish between multiple wireless conversations. Depending on the level of mobility, CDMA provides 8 to 10 times the capacity of AMPS and 4 to 5 times the capacity of TDMA systems. CDMA can efficiently uti­lize the spectrum and serve many sub­scribers without requiring extensive fre­quency planning.
History
Since the startup of the first commercial CDMA network in Hong Kong in Septem­ber 1995 CDMA has established itself as a worldwide mobile radio standard. It has not only been successful in its country of origin, the USA, as well as in Korea and Japan, but all over the world. With its still booming growth rates CDMA today is – besides GSM – one of the most important digital 2nd generation mobile radio standards. CDMA is therefore also suited as the leading-edge technology on the way to 3rd generation mobile radio.
cdmaOne options
Taking the current development on the market into account, Rohde& Schwarz has extended the proven modular con­cept of the CMU200 with cdmaOne func­tionality. The following options make the CMU 200 a compact radio communication tester for all TIA/EIA-95-based cdmaOne mobile phones:
CMU-B81 (cdmaOne signalling unit)
CMU-K81 (cdmaOne test software for
cellular band)
CMU-K82 (cdmaOne test software for
PCS band)
CMU 200 is also the first choice as a tester for cdmaOne – especially in harsh pro­duction environments – because of its outstanding measurement speed, ultra­high accuracy and unrivalled reliability which is also a result of the innovative ventilation concept. Thanks to the modu­lar concept of CMU200, cdmaOne func­tionality plus GSM, TDMA (TIA/EIA-136), AMPS and other standards such as Blue- tooth can be implemented in a single unit. Which other radio communication tester can boast such superior features?
cdmaOne functionality
In cdmaOne mode, the tests are based on the TIA/EIA-95A, TSB-74, and J-STD-008 cdmaOne airlink standards. In addition, the cdmaOne option supports also the standards ARIB-T53 and Korean PCS. The tester emulates a code division multiple access base station, makes a call to the mobile, and tests all essential parameters of a cdmaOne mobile station. The tester can measure the following key parame­ters among other tests:
Power measurements:
– Open-loop time response – Gated output power – Minimum output power –Maximum output power – Side band suppression
Receiver quality measurements:
– Frame error rate (FER) – With additional AWGN generator
to simulate noise caused by other cdmaOne calls at the same fre­quency
– Predefined configurations for sen-
sitivity and dynamic range
Transmitter quality measurements:
–Waveform quality – Error vector magnitude –Phase error –Magnitude error – Carrier feed through and
I/Q imbalance
– Frequency accuracy
Handoffs:
–RF channel –CDMA inter band – Handoff to AMPS – PN offset – Frame offset
Non signalling Measurements:
–Power –Waveform quality – Frequency error – Carrier feed through – I/Q imbalance
All measurements are implemented according to test specification IS-98C. Parameters and limits are predefined to meet the IS-98C test requirements. This allows easy pass/fail decisions without the need of reconfiguring the test setup.
Graphical representation of transmitter measurements like open loop time response, gated output power and modu­lation measurements are helpful tools especially in R&D environments.

CDMA know-how
Rohde&Schwarz is not a newcomer in the field of CDMA, but has many years of experience. As early as 1996 Rohde& Schwarz and Tektronix launched a profes­sional radio tester for CDMA mobiles. Worldwide this extremely successful tester sold thousands of units and has undergone permanent enhancement and adaptation to remain state-of-the-art. CMU200 builds on this success and is able to perform cdmaOne mobile station tests using thoroughly proven test and measurement methods, and also offers the possibility of enhancements for future technologies
CMU200 offers a separate menu for handoffs. In addition to handoff targets such as operating status or network to which CMU200 is to switch, the required target parameters as for example channel number etc can be configured. This enables handoff to AMPS as well as handoff to and from the voice loopback mode

CDMA2000-1X im CMU
CDMA2000 overview
CDMA2000 arose from the further devel­opment of cdmaOne (TIA/EIA-95) and is an enormous step towards 3G. Besides higher data rates and considerably improved efficiency, CDMA2000 is partic­ularly noteworthy for its downward com­patibility to cdmaOne. Nine different con­figurations (radio configurations RC1 to RC9) in the forward link and six radio con­figurations in the reverse link define the different connections which are specified in the IS-2000 standard.
RC1 and RC2 define cdmaOne con-
nections for rate set 1 and rate set 2
RC3 to RC5 in the forward link (or RC3
to RC4 in the reverse link) define CDMA2000 connections for spreading rate 1 (CDMA2000-1X)
RC6 to RC9 in the forward link (or RC5
to RC6 in the reverse link) are CDMA2000 connections for spreading rate 3 (CDMA2000-3X) only.
Compared to cdmaOne, CDMA2000-1X doubles the capacity for pure voice trans­mission and provides a maximum packet data rate of 307 kps on a single 1.25 MHz carrier. CDMA2000-1X is a recognized IMT-2000 3G standard, already success­fully established in Korea – and will soon be implemented in Japan, the USA, Can­ada, Mexico and Brazil. Its application in Eastern Europe is planned as well.
CMU CDMA2000-1X options:
The CDMA2000 standards will be imple­mented in conjunction with our proven cooperation partner Tektronix. By sup­porting the CDMA2000 standard, Rohde&Schwarz consequently enhances the functionality of the CMU200 multi­mode platform.
The central component of the CDMA2000-1X option is the signalling Unit CMU-B83, which is a prerequisite for enhancing the CDMA2000-1X functional­ity in the CMU200. The CMU-B83 is designed for maximum conformity to the standard. The CMU-B83, of course, does not only support pure CDMA2000-1X high-speed data links, but also enables the links of the previous TIA/EIA-95A/B standards.
All tests, which could be performed with the cdmaOne option in conjunction with the CMU-B81, are also available in the new CDMA2000 option. The CMU-U83 upgrade option is a cost-efficient upgrade solution from Rohde&Schwarz for cus­tomers who have already acquired the cdmaOne option in the CMU200.
CDMA2000-1X is used in diverse fre­quency ranges. The standard currently prescribes ten different band classes all of which are supported by the CMU200 with its universal hardware concept.
The following options are available for the CDMA2000-1X:
CMU-B83: CDMA2000 signalling unit
(essential)
CMU-U83: cost-efficient hardware
upgrade from CMU-B81 to CMU-B83
CMU-U65: 3G DDC (additional DSP for
the digital board, essential)
CMU-K83: CDMA2000-1X software

CMU-K84: CDMA2000-1X software
for cellular bands
CMU-K85: CDMA2000-1X software
for PCS bands
CMU-K86: CDMA2000-1X software
for IMT2000 band (band class 6)
The universal hardware and software concept of the CMU200 represents the optimum solution for the future develop­ment and challenges of the CDMA stand­ard over the next few years.
CDMA2000-1X functionality
The similarities with cdmaOne (same physical conditions and downward com­patibility), makes the CDMA2000-1X T&M concept very similar to that of cdmaOne. There are, however, major dif­ferences as to the protocols.
The CMU200 supports connections in all radio configurations defined for the CDMA2000-1X, i.e. TIA/EIA-95 combina­tions as well as the usual CDMA2000-1X high-speed connections.
Code Domain Power is a new and highly important measurement for mobile phones in CDMA2000. Since several code channels are now transmitted simultane­ously in the reverse link, it is necessary to check whether the power distribution of the different channels complies with the test specification (TIA/EIA-IS-98-D) for CDMA2000. The measurement technol­ogy in the CMU200 is based on the ProbeDSP high-speed measurement of the code domain power. The emphasis is on fast measurement technology and clear and concise representation.
Of course, the CMU200 also supports the requirements placed on the gpsOne test application; the CMU200 meets the high demands for frequency and phase accu­racy.
The CDMA2000-1X implementation in the CMU200 is based on the TIA/EIA IS-2000 Rev. 0 standard; the measurements com­ply with the TIA/EIA IS-98-D standard.

As with all mobile radio net­works supported by the CMU 200, two different measurement modes are basically available:
On the one hand, there are tests in the “non-signalling-mode”, which permit an analysis of the mobile without registration in the base station and without actual call setup. For this pur­pose, the CMU generates a base station signal with all the physi­cal channels required, which are user-configurable. This measure­ment mode complies in particu­lar with the demands for high measurement speed in produc­tion lines.

Bluetooth™ measurements in CMU200
General
The CMU200 with the Bluetooth option can set up a Bluetooth connection to a Device Under Test (DUT) via the RF inter­face. The CMU200 switches the DUT into test mode and performs a number of basic RF measurements (TX and RX). According to the Bluetooth Test Mode Specification the DUT has to be locally enabled for the test mode operation. All measurements can be performed in hop­ping-, reduced hopping- or non-hopping­mode. The CMU200 supports measure­ments using DH1, DH3 and DH5 packets.
The coupling between the CMU200 and the DUT can be either via a cable or a cou­pler, depending on the implementation of the DUT.
Applications
The Universal Radio Communication Tester CMU200 with the Bluetooth option is the ideal instrument for production, development and maintenance of any kind of devices with integrated Bluetooth wireless technology.
The CMU200 can also be equipped with additional options for cellular standards like GSM, AMPS, TDMA or CDMA. There­fore the CMU200 is an ideal tester for mobile phone production, as it offers measurements in line with Bluetooth wireless technology and cellular stand­ards in one instrument. With a further extension, which is already in develop­ment, the CMU200 will be able to run Bluetooth measurements and cellular measurements simultaneously. This means the total test time for a mobile phone will not be increased by the Blue- tooth tests because the two types of tests can take place at the same time.
Parallel operation for high meas­urement speed
Due to the high measurement speed and large memory capacity of the CMU, trans­mitter and receiver measurements can be carried out in parallel. When measure­ments are performed during frequency
hopping, a great test depth is rapidly attained. Only a few seconds are required between call setup, transmitter and receiver measurements and call detach.
Many convenient measurement functions
The CMU offers a great number of statis­tical monitoring and measurement func­tions. It is possible, for instance, to define individual tolerances for each measured value and to stop a measurement sequence after a certain number of meas­urements or when a tolerance has been exceeded. Besides the common traces for power and modulation versus time, aver­aged minimum or maximum traces can also be displayed over a userdefined number of packages.
Compliance with existing Blue­tooth standards
The CMU200 is compliant with the Blue­tooth core specifications Ver. 1.0 B and
1.1. The Bluetooth Test Mode (Core Spec. Part I:1) is implemented with all com­mands needed to perform the TX/RX measurements.
The Bluetooth RF Test Specification Ver. 0.9 describes RF test cases for the Bluetooth qualification process. Rohde&Schwarz offers the Test System TS8960 for Bluetooth qualification tests, which is fully compliant with the RF Test
Specification. Although the CMU 200 was not designed for qualification tests, the RF test specification was taken as a guideline for the implementation of the CMU200´s Bluetooth measurements.
Signalling
Setting up a Bluetooth connection
The CMU200 acts as the master of a Blue­tooth piconet, the DUT as a slave. The
CMU200 is able to perform the inquiry procedure for the identification of all Bluetooth devices within range of the CMU200. All devices found are listed on the display and one of them can be selected for the paging procedure. The CMU 200 then establishes the connection to the DUT and switches it into test mode operation.
The inquiry procedure can be skipped, if the Bluetooth device address of the DUT is already known. In this case a shorter setup time for the connection can be achieved. This is important for production tests of Bluetooth devices to increase the maximum throughput of a production line.
Signalling information from the DUT
The CMU200 is able to display a variety of information which is received from the DUT (eg device name, version numbers, service class, supported features).

The connection control menu allows to inquire
addresses of all Bluetooth
devices in range. The
“Device to page” softkey
then selects the DUT for
the measurements tests. Alternatively the input of a known address is possible

the frequency at the start of the packet and the frequency in the pay­load)
Maximum drift rate (maximum drift
rate anywhere within the packet pay­load)

For RX measurements, the built-in signal generator generates a selectable bit sequence, which is looped back in the DUT and demodulated and processed by the CMU200 again. The TX level of the CMU200 can be adjusted for this meas­urement. The BER application supports defining up to five test programs. Each program can independently set settings such as control parameters, limits, repeti­tion or statistical cycles.

WCDMA in CMU200
The need for higher data rates is the trend in our information-oriented society in the new millennium. The enhancement of mobile phones takes this need into account on the way to the next genera­tion of wireless communication. How to cover these future challenges? Driven by ideas of the first and second generation (SIM, global roaming, military CDMA technology, data services), WCDMA will take all of these fundamentals to unprec­edented levels and add new applications and higher data security. Derived from Asian, American and European ideas, "3G" is getting ready to be the mobile solution for future needs as well as the current applications.
WCDMA
Depending on the level of mobility, WCDMA provides several times the capacity of 2nd generation CDMA or TDMA systems.
Thanks to the modular concept of CMU200, WCDMA functionality plus e.g. GSM, TDMA (TIA/EIA-136), AMPS and other wireless standards such as Blue­tooth, can be implemented in a single unit at the same time.
WCDMA FDD functionality
The tests are based on the 3GPP/FDD, release 99 WCDMA radio link standards version June 2001. The CMU200 can eas­ily be upgraded to different functionality steps by means of hardware and software options for non-signalling Tx/Rx measure­ments and signalling measurements. All measurements are following the 3GPP specification TS 34.121. This is especially interesting due to the variety of different filter bandwidth and shapes for ACLR, SEM, MIN power, MAX power, etc that are to be used according to the specifica-
tion. Due to the highly user-friendly menu concept, the CMU200 provides quick access to all measurements desired and optimizes handling and consequently efficiency.
Non-signalling mode
The non-signalling mode is for generating and analyzing WCDMA (3GPP/FDD) sig­nals within the frequency range from of the CMU200 base unit. CMU200 pro­vides WCDMA-specific TX measurements on signals with up to 6 DPDCHs such as
ACLR (Adjacent Channel Leakage
Power Ratio): Two measurement modes, Filter (Bargraph) and FFT (cont. spectrum) method: Absolute or relative readout
OBW (Occupied Bandwidth)
SEM (Spectrum Emission Mask)
CDP (Code Domain Power): CDP vs all
codes, CDP vs DCH channels, RHO vs all codes, RHO vs DCH channels. All measurements in relative or absolute readout, splitted into I and Q parts
Modulation (for 3GPP or general
QPSK): EVM (Error Vector Magnitude), Magnitude Error, Phase Error, Fre­quency Error, I/Q Offset, I/Q Imbal­ance, Peak Code Domain Error, RHO (Waveform Quality)
Power: MAX, MIN, OFF (UE test mode)
Autoranging for received UE signal
The non-signalling mode allows tests of all essential RF parameters of the con­nected UE (User Equipment). The meas­urements work in unsynchronized mode. No time consuming call setup is done to evaluate UE performance using these measurements.
RX measurements
A synchronization (but still no call setup) is needed for the RX evaluation and some additional TX measurements, such as
Inner Loop Power Control with TPC
commands: TPC stepping measure­ment (UE receives TPC commands from CMU200 generator)
Receiver Quality: BER, BLER, (with UE­assisted evaluation, no RF loopback)
The generated channels and functions available are
P-CPICH/P-SCH/S-SCH/P-CCPCH/
DPCCH/DPDCH
TPC profiles
In conjunction with the Rohde&Schwarz Baseband Fading Simulator ABFS and the planned option CMU-B17, conditions of fading may be simulated and evaluated with CMU200.
FDD signalling mode (planned)
The CMU200 simulates a WCDMA base­station RF interface including the signal­ling protocol so that a mobile can be tested with regard to different signalling parameters. All necessary network and Node B (base station) parameters such as control and data channel configurations ca n b e s et. This mo de wi ll be su ppor ted i n a next step. In addition to the non-signal­ling tests it provides features such as
Power: MAX, MIN, OFF (UE signalling mode)
Power control: ON/OFF time mask, open loop power control, inner loop power control (3GPP mode)
Receiver Quality: BER, BLER, (with RF
loopback)
Call setup and release / paging

Test mode connection
Signalling test allows tests in an environment closer to a real live network. However in a produc­tion context they might not be absolutely neccessary.
WCDMA development
With its great versatility the CMU200 is also a suitable tool for the development of mobile phones. Four configurable RF connectors are provided to ena­ble flexible signal levels. The clearly structured and user­friendly menu design together with the clear-cut screen layout provides quick access to all fea­tures and ensures trouble-free monitoring of the device under test. The tester can be switched between 3GPP and general QPSK modes to increase the usa­bility with DUTs under develop­ment.

Quality assurance
Due to its high measurement repeatability and accuracy, the CMU200 is the right choice to ensure a consistently high qual­ity standard of all your deliveries. WCDMA-specific measure­ments such as BER, EVM , and full implementation of compli­mentary (i.e. ACLR- and OBW-) measurements provide an excel­lent test platform to guarantee

the production of high-quality devices.
Production of mobile phones
The production of mobile phones requires time-efficient and cost-effective means that ensure both high throughput and state-of-the-art accuracy. Thanks to the unique IEC/IEEE-bus concept of the CMU200, these two goals can be easily achieved in your production line. The intelligent handling of the received GPIB commands thoroughly optimizes the measurement speed for WCDMA-specific measurements. In practice, this will mean reduced test time and enhanced test yield.
Switching standards
ACLR measurements are available using two differing measurement methods and corresponding displays. In this screenshot, the ACLR is measured using the filter method to obtain results for 5 channels. The scalar display except center channel (0MHz) may be switched to absolute readout as well
The flexibility of CMU200 makes for quick and simple switching between different standards. This is very important for e.g.
