  • Overview of Tests on Radar Systems and Components

    The scope of the subject “radar” has expanded in the recent years in terms of its technical evolution and spreading of applications. This application note along with its corresponding white paper 1MA207 show how to use the R&S radar product portfolio to tackle test and measurement tasks in modern radar technology. Target groups are students who want to become familiar with radar issues as well as radar professionals who want to solve certain test and measurement tasks.

  • Testing airborne radios to the limits

    Replace extensive field tests on fast frequency hopping radios by simulating real-world radio link conditions in the lab

  • Verify your avionics navigation equipment

    Rohde & Schwarz offers unique one-box solutions for reliable testing of air navigation systems such as ILS, VOR and DME.

  • Noise Figure Measurements on Amplifiers in Pulsed Mode

    Power amplifiers in digital TDMA mobile phones are fed with current only during the active slot to save power. Using conventional measuring equipment, the noise figure, an important parameter in power amplifiers, can only be determined with the amplifier in continuous operation. However, continuous operation can lead to amplifier overload and produce distorted results. Now there is a convenient way of determining the noise figure of amplifiers with pulsed power supply: using a Spectrum Analyzer (FSP or FSE or FSIQ or ESI), Noise Measurement Software FS-K3 and a function or pulse generator.

  • Test of DME/TACAN Transponders

    This Application Note describes the operating principle of DME (Distance Measurement Equipment) that is used for distance measurement in aviation. It also describes various test scenarios for the maintenance of a DME transponder. These tests require an R&S®SMA100A signal generator with R&S®SMA-K26 DME modulation option, and an R&S®NRP-Z81 wideband power sensor.

  • Antenna Measurements, RCS Measurements and Measurements on Pulsed Signals with Vector Network Analyzers R&S®ZVM, R&S®ZVK

    This application note describes the suitability of the R&S®ZVM and R&S®ZVK as multichannel microwave receivers for antenna measurements and RCS measurements including measurements on pulsed signals. Application examples describe the measurement possibilities on pulsed signals using the R&S®ZVM/ZVK as stand-alone units. In addition, various R&S®ZVM/ZVK-based antenna measurement systems of the March Microwave company are presented in detail.

  • Pulse Train Master for the R&S Signal Generators

    This Application Note describes a software program that provides easy creation and transfer of Pulse Trains between a PC and the R&S SMB100A, R&S SMA100A and R&S SMF100A analog signal generators with the Pulse Train option; or between a PC and the ARB of R&S SMBV100A, R&S SMJ100A or R&S SMU200A vector signal generators.

  • 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.

  • Hardware in the Loop (HIL) Testing with a GNSS Simulator

    The vector signal generator and GNSS simulator R&S®SMBV100A is remote-controllable in realtime and can therefore be implemented into a dynamic HIL environment. The HIL simulator can dictate position coordinates, kinetic parameters, and vehicle attitude information based upon which the R&S®SMBV100A updates the simulated receiver movement in realtime.This application note presents background information and details about operating the R&S®SMBV100A in HIL applications.

  • RSCommander

    Versatile Software Tool for Rohde & Schwarz InstrumentsRSCommander is a versatile software tool for a wide range of Rohde & Schwarz spectrum-, network analyzers, signal generators and oscilloscopes. It allows for automatic instrument discovery, making screenshots, reading traces, file transfer and simple script creation.
