WCDMA generator for fast testing of 3G mobile radios: Universal Radio Communication Tester R&S CMU200
The first public WCDMA (FDD) network to the NTT DoCoMo standard went into operation in Japan in October 2001, so an increase in the production of mobile phones can be expected for the year 2002. In mid-2001 already, Rohde & Schwarz presented the first Universal Radio Communication Tester R&S CMU200 with WCDMA measurement functions. The following article illustrates how to
make excellent use of this tester in the development and production of 3G mobile radios.

Measuring EDGE signals: Universal Radio Communication Tester R&S CMU200
The mobile radio future means even greater speed on the data highway. The HSCSD 1) and GPRS 2) technologies recently introduced by network operators are just the beginning; the potential for more speed in 2.5G networks is far from exhausted.

Measuring the acoustic characteristics of 3G mobile phones: Audio Analyzer R&S UPL
Good acoustic reproduction quality is the most important characteristic for troublefree communication with mobile phones. The trend towards ever smaller and lighter phones does not exactly make life easier for the designer. With the new UPL-B9 option, all the tests for handset measurements defined in
3GPP TS26.132 are now available on the Audio Analyzer R&S UPL together with the Radio Communication Tester R&S CMU200.

Electrical,mechanical and optical performance testing of telephones: Production test systems based on R&S TSVP
The R&S TSVP [*] test platform, the basis of many Rohde & Schwarz production test systems, allows
optical testing of displays by cameras thanks to a newly implemented image processing function. The latest application demonstrating the versatility of this production test platform is the fully automatic
performance test of business telephones in the Leipzig Siemens production line. The test system
allows the stimulation of the devices under test (DUTs), electrical and acoustic tests, as well as optical
inspection of display elements.

Accurate,realtime characterization of balanced and multiport components: Network Analyzers Advantest R3765CG / R3767CG
There is increasing use of balanced components in modern electronic products such as mobile phones. They consume less power than unbalanced components, yielding the advantage of longer operation and standby. But balanced components mean completely new test requirements - optimally met by two network analyzers from Advantest.

TV Test Receiver R&S EFA: Eye monitoring for continuous detection of digital TV signals
Rohde & Schwarz presents a new display for the analysis of digitally modulated signals (QAM and 8VSB) to go with the Test Receivers R&S EFA, making a valuable contribution to the evaluation and monitoring of advanced communication systems. This innovative method (patent pending) is based on the classic constellation diagram, expanded by the dimension time. It opens up completely new possibilities for judging quality and errors.

High-definition TV pictures of the future: MPEG2 Generators R&S DVG / R&S DVRG
The MPEG2 Generators R&S DVG and R&S DVRG can be used in many ways, e. g. in the production of set-top boxes, for the installation of transmission links or for performing test sequences.
A special and important feature is the large signal repertoire stored in the generators. The versatile signal set has now been extended by the new DV-HDTV option, adding pictures for high-definition TV (HDTV). This makes the generators true allrounders in digital TV measurements.

VHF Transmitter Family R&S NM / NW7000: Liquid-cooled VHF TV transmitters
The introduction of the R&S NM/ NW7000 expands the family of liquid-cooled, high-power transmitters to the VHF range. The transmitters of the UHF family have already met with excellent acceptance on the market, more than 350 systems having been sold since they were launched two years ago. Rohde & Schwarz is thus able to offer a uniform transmitter concept for the two major TV frequency bands. Thanks to their modular design, the transmitters can be configured for both digital and analog TV.

20 kW TV transmitters - compact and mobile: UHF Transmitter Family R&S NH/ NV7000
In 1998, Crown Castle International was the world’s first operator to set up a nationwide, terrestrial digital broad-casting network with four multiplexers. Rohde & Schwarz supplied more than 80 transmitters of the power classes 750 W to 3 kW for this network in Britain. Staff of Crown Castle International and of the Rohde & Schwarz UK subsidiary jointly set up the network over a number of months and put it into operation. In addition, Rohde & Schwarz supplied eight mobile digital transmitters as backups.

Liquid-cooled TV transmitter at airy height: TV Transmitter R&S NH6050
Acrodyne Industries Inc., Rohde & Schwarz’s US partner, scored with a TV transmitter order for the Houston Tower in Texas. The system installed there is one of the first liquid-cooled transmitters in the USA. The Rohde & Schwarz concept won out where air-cooled transmitters otherwise dominate. This report by the operator once more confirms customer satisfaction with high-tech transmitters from Rohde & Schwarz.

MPEG2 over ATM - the state of the art:
In recent years, ATM (asynchronous transfer mode) has established itself as a standard in many telecommunication networks because of its many benefits. In contrast to circuit-switched modes, ATM is packet-oriented and allows assignment of transmission capacity to meet demand.

Members only - confidential telephone and data communication: R&S TopSec product family
Anyone who has suffered damage once will be very careful the next time, that is what the proverb "once bitten, twice shy" is meant to convey. But what happens if you fail to notice
the damage in the first place? This may be the case when a business becomes the victim of industrial
espionage. So the maxim "better safe than sorry" seems to be the better one, because the losses caused by industrial espionage in Germany alone have been estimated at € 10 billion
every year. For this reason, both the German Information Security Agency and the EU Commission advise all businesses to protect, i. e. encrypt, all communication channels used to
transmit sensitive information.

Free software device drivers for remote control of T&M equipment:
Many Rohde & Schwarz customers prefer the graphical programming languages LabVIEW from National Instruments or VEE from Agilent when writing applications for T &M equipment. Quite often, C-based LabWindows/CVI from National Instruments and Visual Basic or Visual C++ from Microsoft/ Borland are also used. As a service, Rohde & Schwarz provides software device drivers free of charge for all these programming languages. All recent T &M equipment is supported, and demo programs
are also often available.
