  • Bluetooth Low Energy Measurements Using R&SCBTgo; Additional Tests

    Nearly all tests in accordance with the Bluetooth low energy test specification V4.0 [1] can be performed using the R&S®CBT alone. Some tests additionally call for signal generators to provide interference signals. This application note describes the tests performed with additional equipment and presents straightforward solutions based on the R&S®CBTgo software.

  • 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.

  • Simulating Automatic Obscuration and Multipath for Realistic GNSS Receiver Testing
    Simulating Automatic Obscuration and Multipath for Realistic GNSS Receiver Testing

    The R&S®SMBV100A is both, a versatile general-purpose vector signal generator and a powerful GNSS signal simulator. It can simulate up to 24 satellites in realtime for testing GNSS receivers flexibly, reliably, and cost-efficiently. The R&S®SMBV100A supports receiver testing under realistic conditions by offering features such as obscuration simulation and automatic multipath generation. Out of a multitude of possible test scenarios – with predefined or user-specific settings – this application note presents some examples to give an impression of the instrument’s capabilities.

  • Measurements on FM Transmitters for Acceptance, Commissioning and Maintenance
    Measurements on FM Transmitters for Acceptance, Commissioning and Maintenance

    Despite the advent of advanced digital transmission methods, analog broadcasting remains highly important. Until now, measurements on FM transmitters in connection with acceptance testing, commissioning and maintenance required using a variety of T&M instruments.

  • Solving Oscillator Frequency Pops (Perturbation)

    This aplication note offers two solutions to dealing with abruptly jumps -- up or down -- in oscillator frequency, causing a lost PLL lock or a variety of other system-related problems.

Microwave USB Power Sensor (MA24105A) Microwave USB Power Sensor (MA24105A)

The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements from 2 mW to 150 W and peak power measurements from 2 W  to 300 W over the frequency range of  350 MHz to 4 GHz. The sensor employs a “dual path” architecture that enables True-RMS measurements over the entire frequency and dynamic range allowing users to measure CW, multi-tone and digitally modulated signals such as LTE, LTE-TDD, GSM/EDGE, CDMA, W-CDMA, WiMAX, TD-SCDMA, WLAN, and LTE. The forward direction path also include a 4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as PEP power, crest factor, CCDF, and burst average power. Another detection circuit on the reverse direction adds reverse power measurement capabilities including reverse power, reflection coefficient (magnitude), return-loss, and SWR. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter.

RF/Microwave Signal Generator: MG3690C RF/Microwave Signal Generator: MG3690C

The MG3690C series of broadband signal generators covers audio, HF, VHF, UHF, RF and microwave frequencies from 0.1 Hz to 70 GHz in single coaxial output and up to 325 GHz or beyond, with external multipliers. Thus, the MG3690C series is an ideal signal source for both RF and microwave requirements, fully configurable for simple to high performance applications.

<B>Injection Current Probes</b> Injection Current Probes

The Injection Current Probe is a device used to inductively couple large RF currents into their conductors. With three separate models differing in insertion loss, aperture and frequency range, these injection probes can be used as an injection source as well as a sensitive monitoring probe for high-frequency bulk injection testing.

Wideband Frequency Synthesizer 29 To 3840 MHz: KY3840A Wideband Frequency Synthesizer 29 To 3840 MHz: KY3840A
The KY3840A is a wideband frequency synthesizer that operates in the 29 to 3840 MHz frequency range that features 1 Hz tuning resolution, +10 dBm output power, an internal temperature monitor, a 6 millisecond tuning time, a selectable frequency external reference input, a single +15 Vdc supply, ±1.0 ppm internal reference stability, and more. This frequency synthesizer will operate from either the internal TCXO reference or an external source. For embedded applications, it can be controlled via a 4-wire serial interface. Alternatively, the synthesizer can be controlled using a PC with an RS-232 serial port.
Cable And Antenna Analyzer: R&S ZVH Cable And Antenna Analyzer: R&S ZVH

The R&S®ZVH cable and antenna analyzer is rugged, handy and designed for use in the field. Its low weight and simple operation make it indispensable for anyone who needs an efficient measuring instrument outdoors for the installation and maintenance of antenna systems.

Switch Matrix: R&S&reg; ZN-Z84 Switch Matrix: R&S® ZN-Z84

The R&S® ZN-Z84 is a 48-port solution designed to complement the R&S ZNB network analyzer. It’s used to test multiport components for the wireless communications market in R&D and production phases. The matrix covers the 10 MHz to 8.5 GHz frequency range and can be controlled and operated directly from the ZNB network analyzer.

Non-Blocking RF Switch Matrix Non-Blocking RF Switch Matrix

A non-blocking RF switch matrix is more complex than the blocking type, but it’s also more flexible.  In this configuration, an input can be switched to multiple outputs.  One input can in fact be switched to all of the outputs at once.  This provides an extra degree of flexibility compared to the blocking architecture.  However, a non-blocking architecture still has the limitation of not allowing two or more inputs to be switched to the same output.  Input 1 for example can be simultaneously switched to every output or selectively switched to several outputs at once, but no other input can be switched to any of the same outputs.
