  • 802.11ad – WLAN at 60 GHz
    802.11ad – WLAN at 60 GHz

    Data rates in the range of several Gigabit/s are needed to transmit signals like uncompressed video signals. Amendment 802.11ad to the WLAN standard defines the MAC and PHY layers for very high throughput (VHT) in the 60 GHz range. This white paper provides an introduction to the technology behind 802.11ad and highlights the test and measurement requirements.

  • eCall Conformance Testing
    eCall Conformance Testing

    Emergency Call (eCall) is a service provided in Europe with the goal of reducing response times for accidents or other emergencies on the roadways. This application note briefly describes the technology behind eCall and presents conformance tests for eCall using the R&S®CMW500 RF tester and the R&S®SMBV100A vector signal generator.

  • Using Enhanced Load-Pull Measurements For Base Station Power Amplifier Designs

    The concept of load-pull simulation is where a load or source impedance is swept by an active device and its performance is measured. Recently, advancements have been made to data file formats by load-pull measurement system vendors to expand the usefulness of load-pull characterization. These new file formats support a sweep of an independent variable such as input power, DC bias, temperature, or tone spacing, in addition to the swept source or load impedance. The NI AWR Design Environment™ software enables designers to import and manipulate these load pull data sets in a circuit simulator which greatly simplifies and speeds the design process, and gives them a broader design space to explore. This white paper covers in-depth information on how to use enhanced load-pull measurements for base station power amplifier designs.

  • Flexible Radar Target Generation Using COTS Test Equipment
    Flexible Radar Target Generation Using COTS Test Equipment

    With the recent introduction of the R&S®SMW200A microwave vector signal generator, Rohde & Schwarz now offers a novel approach to flexibly and conveniently generate multiple radar target echoes for systems up to 20 GHz.  When used in combination with the R&S®FSW signal and spectrum analyzer, these commercial off-the-shelf (COTS) test instruments can be configured to support flexible radar target generation including range and target velocity emulation.

Statistical Power Sensor: 7022 Statistical Power Sensor: 7022

A signal’s average power isn’t a sufficient enough control variable for modern day communications. It’s still an important parameter, but today’s signals typically require more diagnostic measurements. Bird’s 7022 is a statistical power sensor that uses statistical sampling techniques to measure the percentage of time the signal exists at a specific peak-to-average ratio.

In-Vehicle eCall Test Solution In-Vehicle eCall Test Solution

In-vehicle systems (IVS) are designed to connect to a public safety answering point when an automobile is an accident. They transmit a minimum set of data to emergency personnel that includes the vehicle’s GPS coordinates. Rohde & Schwarz recently developed a setup for manufacturers of these automatic in-vehicle systems (IVS) for reliability testing.  

R&S FSUP Signal Source Analyzer R&S FSUP Signal Source Analyzer
The Signal Source Analyzer R&S FSUP offers the user a high-end spectrum analyzer (R&S FSU) up to a maximum frequency of 50 GHz, combined with a phase noise tester based on the PLL method. In addition, the R&S FSUP is equipped with two independent, very low-noise DC ports. Supply voltage and tuning voltage can be individually defined for each port via a clear-cut menu, which enables control of external oscillators or a complete characterization. Like an FM/PM/AM demodulator – the R&S FSUP records the oscillator signal over time. With the functionality of a phase noise tester, time domain and spectrum analyzer combined into a single device with a maximum input frequency of 50 GHz, the R&S FSUP is the optimum instrument for development and production.
