Rohde & Schwarz extends its lead in network analysis with first four-port network analyzer up to 67 GHz

Mar 04, 2010 - The high-end R&S® ZVA67 vector network analyzer from Rohde & Schwarz is now also available as a four-port model. This is the first network analyzer on the market to feature four test ports for measurements up to 67 GHz. Its high dynamic range (110 dB at 67 GHz) and output power (6 dBm at 67 GHz) give the R&S® ZVA67 the flexibility and performance required for characterizing components and modules in the microwave and millimeter-wave range. It allows users in research and development to determine the S parameters of multiport devices quickly and with high precision. As an extra benefit, the analyzer's four internal signal sources reduce test system complexity and the number of instruments required, e.g. for measuring frequency-converting DUTs, because no external signal generators are needed.

The new R&S® ZVA67 vector network analyzer, with its unique architecture that includes four ports, four integrated signal sources and eight receivers, enables measurements on multiport devices such as mixers, couplers or balanced DUTs, with just one instrument. With its high output power of 6 dBm and wide power sweep range of > 40 dB, the R&S® ZVA67 is able to characterize the small- and large-signal behavior of active components. Linear and nonlinear measurements can be carried out using a simple test setup. This advantage becomes apparent, for example, when measuring the S parameters or intermodulation of mixers or amplifiers, or when measuring the group delay and phase of up- or downconverters.

Offering a frequency range up to 67 GHz, the four-port R&S® ZVA67 covers the band intended for the wireless transmission of multimedia data (wireless HDMI). Additional applications can be found in the aerospace and defense sectors, including measurements on inter-satellite communications systems and point-to-point communications systems. The analyzer’s wide dynamic range of 110 dB at 67 GHz also makes it a valuable tool for material measurements or microwave imaging applications.

Frequency converters from Rohde & Schwarz extend the frequency range of the four-port network analyzer to beyond 325 GHz. Due to its outstanding performance, the R&S® ZVA67 enables users to advance the development of materials and technologies into much higher frequency ranges.

Shaping the future of digital television: Rohde & Schwarz tests hands-on knowledge of young engineers

Feb 26, 2010 - It is hard to imagine life today without digital television. Rohde & Schwarz puts young engineers to the test in this field. For the seventh time the company is teaming up with the German Association for Electrical, Electronic and Information Technologies (VDE) to host its international case study competition. Engineering students from Germany and Singapore are invited to explore the DVB-T digital television standard and its successor, DVB-T2.

DVB-T has been gaining ground since 2002. However, this standard, which supports digital TV reception via antenna, is beginning to run up against its transmission capacity limits. Consequently, the next digital broadcasting technology generation, DVB-T2, is already waiting in the wings. The motto of this year’s case study competition is, "Move up to the next level – the future of digital broadcasting is in your hands!" The students’ assignment will be to prepare a presentation and then deliver it to network operators or program providers. The goal is to persuade them to use DVB-T2 to broadcast their services. To prepare their presentations the students must accomplish various tasks along the way. After all tasks are completed, each university’s winning team will be selected by a jury made up of a professor from the university as well as an engineer and a human resources manager from Rohde & Schwarz.

The preliminary rounds of the 2010 case study competition will take place between May 10 and June 7 at the participating universities, with the exception of Singapore. The two qualifying rounds for students at the National University of Singapore (NUS) and Nanyang Technological University (NTU) will take place at the Rohde & Schwarz office in Singapore.

In the final, scheduled for June 17/18 at Rohde & Schwarz headquarters in Munich, the winning teams from the various universities will go head to head. The winners will take home Apple iPads as well as a 2000 euro cash prize for their university. But your participation will be rewarderd in any case: Every participant achieves a technical text book from Rohde & Schwarz.

R&S®TS-EMF portable system for EMF measurements with new frequency range from 9 kHz to 6 GHz

Feb 25, 2010 - The R&S®TS-EMF portable system is ideal for safety-related electromagnetic field measurements, since it is highly reliable and makes it easy to prove compliance with the limits of different radio services. The new R&S®TSEMF-B2 and R&S®TSEMF-B3 isotropic antennas from Rohde & Schwarz perfectly meet the requirements for rolling out and for widespread use of new wireless technologies that increase the intensity of electromagnetic fields in the environment.

New communications services such as WLAN 802.11a and WiMAX™, with frequencies between 3 GHz and 6 GHz, require a frequency range extension of the measuring equipment for surveys, risk communication and studies. The R&S®TSEMF-B2 isotropic antenna can cover this extension. The antenna, featuring a frequency range from 700 MHz to 6 GHz, is also suitable for measuring EMF standards such as EN50499 and can measure all relevant wireless services in a single operation.

Many LF and HF transmitters contribute significantly to the total EMF budget, even if they are not in the direct vicinity of the measurement site. The new R&S®TSEMF-B3 isotropic antenna, which has a frequency range from 9 kHz to 200 MHz, makes it easy to perform measurements for standards that require evaluation of relevant transmitters starting at 9 kHz. The antenna even performs higher-sensitivity measurements in the frequency range from 30 MHz to 110 MHz, allowing more distant FM transmitters to be detected.

Compact EMC test solution

- The new R&S® R-Line test chamber from Rohde & Schwarz combined with the R&S® TS8996 test system delivers an EMI/EMS test performance and accuracy for wireless devices that is comparable to that of systems 10 times larger. During development this compact solution replaces a complete anechoic chamber and complex setup for the critical frequency range of 800 MHz to 18 GHz. It is as effective up to 40 GHz. The R&S® R-Line fits into any lab and will significantly reduce infrastructure investments for manufacturers and test houses.

The Rohde & Schwarz solution meets all S-VSWR validation requirements defined in the CISPR16-1-4:2007 standard. This translates into a compact and economical solution for measurements in the microwave range that can be used in the R&D lab.

The benefits of this compact, high-performance system are numerous, including the ability to optimize factors such as radiated spurious emissions during the development phase. This can eliminate complex modifications during the final conformance tests, which significantly reduces time-to-market.

Further test capabilities in the microwave range can be added with software upgrade packages. This allows designers to determine parameters such as radiated power and sensitivity and to carry out free-space, over-the-air (OTA) performance measurements. As a result, comprehensive RF OTA characterization of the wireless device can begin while the device is still in development.

The R&S® TS8996 test system consists of tried-and-tested instruments from Rohde & Schwarz that stand out for their unsurpassed measurement accuracy and reliability: A typical system includes the R&S CMU200 mobile radio tester, the R&S® FSP or R&S® FSU spectrum analyzer, and a signal generator for calibration.
