UE measurement reports: checking mobile phone measurement accuracy: Universal Radio Communication Tester R&S ® CMU 200
Mobile phones have to measure characteristics such as the pilot channel power of the base station and then send the results to the radio network. Such measurements strongly affect the distribution of resources at the radio interface. The R&S ® CMU 200 triggers the mobile phone to carry out these measurements and presents the results in a clear-cut manner. The R&S ® CMU 200 can also set the mobile phone to compressed mode, in which the phone performs measurements on neighbour frequencies.

Testing cdma2000 data applications: Universal Radio Communication Tester R&S ® CMU 200
With the commercial launch of thirdgeneration mobile radio network standards, there is an increasing demand for test equipment to verify the proper functioning of data applications. This presents a new challenge to mobile radio testers that falls between pure RF parameter tests and sophisticated protocol tests. Standard cdma2000 mobile radio networks have already been in commercial use since 2000 in many Asian countries (e. g. Japan and South Korea), the Americas ( e. g. the USA and Canada), as well as in Eastern Europe. The R&S ® CMU 200 [1] now offers extensive test capabilities for data applications for this important global 3G standard.

Reducing test time through automation: Protocol Tester R&S ® CRTU-G
Being able to reduce test time is increasingly important in development laboratories. Completely automated test sequences are an effective means of achieving this goal. In addition, tests can be performed at off times – at night, for example. The operational software supplied with every R&S ® CRTU-G contains a preconfigured solution for such scenarios. It can significantly contribute to shorter test time.

Efficient programming interface for UMTS protocol development: Protocol Tester R&S ® CRTU-W
The R&S ® CRTU-W (FIG 1) has long been known for its convenient and powerful TTCN interface, which was designed and optimized for conformance testing. Research and development, however, require a flexible yet easy to operate programming interface. The new MLAPI software option (R&S ® CRTU-WT 02) now provides you with the right tool for R&D applications.

Complete radio solution for Bangkok’s underground train system: TETRA Mobile Radio System ACCESSNET ®-T
For years, the inhabitants of Bangkok have been suffering from daily traffic chaos. To tackle this problem, the Thai government drafted ambitious plans to build an underground train system. Siemens was commissioned to provide the trains and infrastructure, including signalling technology, power supply, depot equipment and communications system. Siemens in turn contracted R&S BICK Mobilfunk GmbH to furnish a complete radiocommunications solution, consisting of the ACCESSNET ®-T TETRA mobile radio system, a control center and the radiocommunications equipment on the trains.

Fast Bluetooth® RF testers compatible with the R&S ® CMU 200: Bluetooth® RF Production Testers R&S ® CBT / R&S ® CBT 32
When manufacturers purchase test tools, the manufacturing costs of Bluetooth® * modules are an important consideration. Increasing integration means falling sales prices, which, in turn, means ever tighter budgets for testing. To meet this trend, Rohde & Schwarz offers two economical Bluetooth RF testers for production – the R&S ® CBT and the R&S ® CBT 32. Both instruments contain the same high-quality and fast T&M technology but are designed for different applications.

Award-winning spectrum analyzer now up to 6 GHz: Handheld Spectrum Analyzer R&S ® FSH 6
The R&S ® FSH6 is the world’s first 6 GHz handheld spectrum analyzer that can directly measure WLAN 802.11a signals, for example. It is the followup to the successful 3 GHz model R&S ® FSH 3 [*], which won the NAB2004 Pick Hit Award. The latest firmware version now adds new functionality to all R&S ® FSH models, including for example receiver mode and frequency tuning based on channel lists.

Hard at work in the Andes regions of Peru: Handheld Spectrum Analyzer R&S ® FSH 3
In the remote Andes regions of Peru, a radio is often the only means of contact with the outside world. Many villages are a day’s hike from the nearest highway and are not served by electrical power lines. The villagers use small, battery-operated radios to listen to radio programs and obtain important information. For this reason, improving radio reception is of fundamental importance to the development of these regions.

Noise – an annoyance? Not with the new noise option!: Vector Signal Generator R&S ® SMU 200 A
With its outstanding signal quality, the Vector Signal Generator R&S ® SMU 200 A meets all expectations even in the most demanding applications [*]. Users frequently need to intentionally apply noise to – or otherwise affect – the “ideal” signal from this generator. The secret is additive white Gaussian noise (AWGN). Yet, even this noise signal needs to be “ideal“. A contradiction in terms? Not with the new option Additive White Gaussian Noise R&S ® SMU-K62 for generating noise.

Securing your investments: VHF / UHF TV Transmitters R&S ® NM 7000 C / NH 7000 C
In the years ahead, more and more TV networks will be retrofitted for digital operation. This means that investments still being made in analog networks need to be secured for the digital age. All analog TV transmitters of the R&S ® 7000 family [1, 2] can be retrofitted for digital operation. This is particularly easy with the Transmitters R&S ® NM / NH 7000 C (C stands for combined). They are available for the power ranges 3.5 kW to 10 kW for VHF (band III) and 3.5 kW to 20 kW for UHF (band IV / V).

DVB-H – new digital multimedia services for mobile terminals:
The combination of Internet and broadcast technologies is creating new multimedia services for mobile phone owners. DVB-H will be the basis for future mobile IP-based datacasting applications. As a result, video streaming will soon be available for mobile battery-operated devices. These services can be received in existing terrestrial DVB (DVB-T) networks for extended periods owing to the energy-saving DVB-H method and in mobile operation even at high speeds. Rohde & Schwarz already supports its customers with equipment during the pilot phase.

Nationwide spectrum monitoring system for Hungary: Spectrum Monitoring and Management System R&S ® ARGUS-IT
In December 2002, Rohde & Schwarz was contracted by the Hungarian regulatory authority NHH (NEMZETI HÍRKÖZLÉSI HATÓSÁG) to supply ten spectrum monitoring stations. The order included setting up an integrated national Spectrum Monitoring and Management System R&S ® ARGUS-IT that had to incorporate the existing central station in Budapest, two monitoring vehicles from Rohde & Schwarz and several fixed stations from another manufacturer. The decision in favour of Rohde & Schwarz followed a thorough evaluation of solutions from different suppliers that NHH had operated in parallel.

Software defined radios – overview and hardware (1):
Software defined radios combine a broad scope of complex radio techniques in one instrument. You can expand them for future techniques, reconfigure them for modified application profiles, and switch them between different radio services. Are they the ready-made solution or merely the concept of things to come?
