Measuring radiated RF characteristics of mobile phones right on the lab bench: Test cells
First-time pass in certification measurements – this is a goal that every developer would like to achieve. The new R&S®DST200 RF diagnostic chamber can make this difficult path much smoother. It allows developers to perform a wide variety of radiated tests and receiver sensitivity measurements on wireless devices (e. g. mobile phones) – and it is available directly on the lab bench.

Powerful software handles nonlinear effects in amplifiers: Test methods
Today’s wireless communications standards place increasingly higher demands on the bandwidth, transmission linearity and power efficiency of the output stages in mobile devices and base stations. Developers must therefore measure, characterize and optimize linear and nonlinear effects of active and passive components. The R&S®FS-K130PC distortion analysis software is a powerful tool for accomplishing these tasks.

More effective than ever: R&S®EMC32 EMC measurement software with new enhancements: Measurement software
New options for increasing the automation and flexibility of test sequences, for measuring antenna radiation patterns and for integrating the software into laboratory management systems make the R&S®EMC32 EMC measurement software even more versatile. It is therefore no surprise that this powerful tool for electromagnetic interference (EMI) and susceptibility (EMS) measurements, with more than 2000 licenses sold worldwide, is the market leader for automatic EMC testing in all relevant sectors and standardization fields.

Realistic simulation: cable TV networks for J.83/B and DOCSIS 3.0: Broadcast test transmitters
Despite faults and interference in cable networks, set-top boxes and cable modems always have to provide perfect reception. Therefore, they are thoroughly tested during development and production to make sure they fulfill this requirement. Rohde&Schwarz offers a system that, for the first time, can realistically simulate cable TV networks. The system consists of the R&S®SFU broadcast test system and several R&S®SFE100 test transmitters.

3D TV test signals in accordance with the HDMI 1.4a interface standard : Baseband signal generators
3D, the runaway hit in cinemas, can now be enjoyed at home. The 3D sensation requires state-of-the-art TV sets that are able to process the corresponding pictures and provide suitable panels. As a result, R&D departments and quality assurance are going to face new challenging tasks. The R&S®DVSG digital video signal generator, which already creates all the required signals, is the ideal tool to meet such requirements.

Europe’s air traffic control on the way to voice over IP : Air traffic control
Voice communications systems will continue to be absolutely essential for the safe handling of air traffic in Europe in the future. But the rapid technical development opens up completely new opportunities for air traffic control (ATC) organizations. They are subjecting these new methods to thorough tests, for high safety requirements must be met. This careful migration is made possible by the radios of the R&S®Series4200 family, because they support several communications technologies that make migration easier.

High-precision calibration of EMC test antennas – also as a service: Antenna calibration
The calibration laboratory of Rohde&Schwarz Messgerätebau GmbH now also performs accreditation measurements of the free space antenna factor. The measurement uncertainty achieved at the Rohde&Schwarz open area test site was verified by Germany’s National Metrology Institute (PTB). This test site achieves the highest accuracy among the three laboratories in Germany that are admitted to perform these types of measurements. The service is also available for measurements on customer antennas.

Change at the helm of Rohde&Schwarz:
Manfred Fleischmann succeeds Michael Vohrer : International
After a long career with Rohde&Schwarz spanning 35 years, including seven years on the Executive Board and five years as its Chairman, Michael Vohrer (62) has retired. An electrical engineer by profession, Vohrer played a key role in the company’s success throughout the years. One of his major contributions was achieving market leadership in the field of mobile radio test and measurement when he headed that division. The company’s entry into the oscilloscope market, which is now underway, marks the end of his long and productive career. On July 1, 2010, his colleague Manfred Fleischmann became President and CEO. Gerhard Geier, previously Head of the Radiomonitoring and Radiolocation Division, has been newly appointed to the Executive Board. Managing partner Christian Leicher remains on the Executive Board.
