Rohde & Schwarz will take advantage of European Microwave Week in Paris (Sept 7-10) to present its T&M highlights for the highest frequencies. The company will showcase its new R&S FSWP phase noise analyser and VCO tester for the first time in Europe. The new R&S FSWP phase noise analyser and VCO tester allows users to measure the spectral purity of signal sources such as generators, synthesisers or voltage-controlled oscillators.

The high-end instrument covers a frequency range of up to 26.5GHz and offers a top dynamic range. The extremely low phase noise of its local oscillator coupled with cross-correlation even makes it possible to easily measure signal sources that in the past required sophisticated test setups.

The noise analyser performs complex measurements at the push of a button and is operated via touchscreen. The instrument can quickly and easily measure the phase noise even of pulsed sources, making the R&S FSWP especially attractive for applications in aerospace and defence.

Looking to the future, 5G is expected to usher in the next generation of mobile radio by 2020. Rohde & Schwarz is involved in numerous 5G initiatives around the globe and supports research activities to make the spectrum in the millimetre-wave range usable for 5G. At the show the T&M specialist will present a test setup that consists of an R&S SMW200A vector signal generator, an R&S FSW67 signal and spectrum analyser and an R&S RTO oscilloscope.

When equipped with the R&S FSW B2000 option, the R&S FSW can analyse signals with a bandwidth of up to 2 GHz. The upper frequency limit of the R&S FSW67 is 67GHz; the new R&S FSW85 even reaches 85GHz with a continuous frequency range.

The R&S SMW200A supports the generation of signals up to 40 GHz and can also be expanded by using external mixers. The test setup on display can generate and analyse wideband signals in the 60 GHz range.

An innovative test solution for the development and production of automotive radar sensors used in driver assistance systems will be showcased by Rohde & Schwarz. There are a few new additions. The turnkey ARTS radar target simulator from ITS and miro-sys now features a reduced simulated minimum range of 6m and an increased bandwidth of 1GHz. As a result, it offers ideal characteristics for testing autonomous emergency braking (AEB) systems or blind spot detection, for example.

The real-time interface for hardware-in-the-loop (HiL) simulators can be used to reproducibly play back real-world test scenarios in the lab in line with Euro NCAP standards. This reduces development costs and time to market.

The R&S FSW85 high-end signal and spectrum analyser, which is the only signal and spectrum analyser in the world to cover the range from 2Hz to 85GHz, and its R&S FSW K60C analysis option for FMCW chirp signals are the perfect complement to the ARTS.

Also on display in Paris will be the USB-compatible R&S NRPxxS as well as the USB and LAN-compatible R&S NRPxxSN three-path diode power sensors. The sensors are each available for three different frequency ranges from 10MHz to 8GHz, 18GHz and 33GHz, enabling 10,000 triggered measurements per second and a minimum trigger repetition rate of 100µs.

In fast continuous average mode, it is even possible to perform more than 50,000 measurements per second. A lower measurement limit of –70dBm results in a very large dynamic range of 93dB. Particularly at low levels, this makes measurements up to four times faster than with previous solutions.

The LAN interface on the R&S NRPxxSN models now allows remote power measurements even over large distances. The power sensor is easy to control from a GUI accessed via web browser. No additional software is needed.

As the requirements for semiconductor tests continue to increase, this also places greater demands on complex on-wafer test systems. The quality of the wafer prober is just as important as the RF performance and functionality of the network analyser, complemented by (calibration) software. Rohde & Schwarz is collaborating with MPI Corporation for high-quality on-wafer test systems. A jointly developed solution will be on display at EuMW.

Probe stations from MPI feature outstanding mechanical stability and offer unique solutions for handling the prober as well as the reproducibility of the measurements.

The QAlibraTM calibration software supports all mid-range and high-end network analysers from Rohde & Schwarz. When combined, the user gets a wide range of measurement functions for passive and active DUTs with high-end RF performance.

In addition, users benefit from the calibration functions of the QAlibria software and from the largest portfolio of calibration methods available on the market, including the tools that enable precise measurements with a multitude of parameters. Power calibration in the range from 10 MHz to 110 GHz is possible with just a single sensor.

For the first time, Rohde & Schwarz will show test and measurement instruments from the broadcast sector at this year's EuMW. For professional A&D satellite applications, data and video transmissions require ever greater bandwidths. This is why DVB standards from the broadcast sector are used. For these applications, the R&S BTC broadcast test centre and the R&S SLG multichannel digital satellite TV modulator are available.

The R&S BTC provides an integrated real-time test environment for simulating the transmission of video and IP data in the satellite channel. The R&S SLG generates satellite signals with various standards and parameters up to a bandwidth of 500MHz. This makes it possible to test all imaginable uplink and downlink configurations as well as satellite payload configurations.

Rohde & Schwarz experts will present 19 workshops and seminars. Along with basic seminars, there will also be technical workshops that cover topics such as the challenges accompanying mm-wave measurements and the generation of pulsed signals for radar applications.
