Testing the 3rd generation
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.

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

Ready for today‘s networks …
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:
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
◆ 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 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.
−130 dBm up to +13 dBm,
−80
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.

(EDGE) is already
implemented.
Thus EDGE bursts

can easily be ana-
lyzed
Universal Radio Communication Tester CMU2009
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-

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.

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.
18 Universal Radio Communication Tester CMU200
Open-loop time response
The open-loop power con-
trol test shows the
response of the mobile sta-
tion to an increase or
decrease in base-station
total power. The default
increase or decrease for
this test is 20 dB. Power
stepping and cdmaOne
levels are user-definable
Gated output power
The gated output power
can be displayed in several
formats. Select FULL DIS-
PLAY to show the total
period of the IS-98 gated
output template. The
period of the full display is
approx. 1500 µs. Select
RISING EDGE (see figure)
or FALLING EDGE to zoom
in to display the 17 ms
period of the rising or falling edge of the waveform.
In each of these displays, a
MARKER may be activated
to display both power
amplitude and relative
time
Modulation measure-
ments: magnitude error
Modulation measurements
serve for assessing the
quality of the mobile’s
transmit part. In addition
to phase error, error vector
magnitude and magnitude
error can be shown graph-
ically at the push of a but-
ton. A clearly arranged

ance, frequency error and

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
for the 450 MHz band (band class 5)
◆ 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).
26 Universal Radio Communication Tester CMU200
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 power menu shows
the results in graphical and
scalar form. Statistical
functions as well as con-
venient markers aid fur-
ther evaluation. The timing
measurement comple-
ments the numerical
power results
The graphical display of
the modulation results
may be spread between 1/
1 and 1/8 of a burst for indepth analysis. The “Max.
Freq. Dev.” and “Min Freq.
Dev.” results allow the
highest and lowest values
for 10 bit long fractions of
a payload to be evaluated
individually

TX measurements
The current measurement values for each
parameter are displayed on the CMU200
screen. Additionally average, maximum
and minimum values are displayed as a
result of a statistical evaluation of a settable number of Bluetooth packets (bursts).
Power measurements
Measurement parameters:
Measurement parameters:
◆ Nominal power (measured as the part
of the burst starting at the detected
1st bit of the preamble (bit 0) to the
last bit of the burst)
◆ Peak power (shows the highest pow-
erlevel within a burst)
◆ Leakage power (measured within de-
fined areas before and after the burst)
Timing measurements
Measurement parameter:
◆ Packet alignment (distance between
ideal master receiver slot and detect-
ed bit 0 of the received burst)
This measurement is displayed on the
“Power“ screen.
Modulation measurements
Measurement parameters:
◆ Frequency accuracy (difference be-
tween measured frequency and in-
The device under test can be connected to the CMU200 via a RF coupler (antenna) or a cable

◆ Frequency drift (difference between
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)
◆ Average, maximum and minimum fre-
quency deviation (calculated over 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
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
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
30 Universal Radio Communication Tester CMU200
◆ 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 ACLR menu
shows all adja-
cent channel
related information in graphical

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.

as many 3GPP UEs for markets with networks of these second generation stand-
