  1. An Introduction To Interference Hunting

    As radio systems have grown and become more complex, the number of interferers has also increased. This white paper introduces the basic concepts of interference hunting and explores the different types of interferers, how to analyze them, and the tools needed for the job.

  2. Using Radar Echo Generators

    Radar testing is usually carried out in a lab as field testing can be expensive and particularly complicated with its setup and operation. This application note presents a solution for testing the complete radar system through the use of Radar Echo Generators.

  3. Evolution Of The Modern Receiver In A Crowded Spectrum Environment

    The Electromagnetic Spectrum is a finite resource and its use is rapidly expanding. Unencumbered access to spectrum has been, and continues to be, critical to many government and commercial systems. As existing RF systems evolve and new communication systems are deployed, the need for additional spectrum bandwidth continues to grow. With federal mandates and initiatives, such as the 500 MHz of federal spectrum released for commercial use by 2020, the impact to spectrum monitoring equipment and the role of spectrum management also must evolve. This article will cover the different functions of the traditional RF measurement instrument architectures and their role in spectrum monitoring.  The basic spectrum analyzer architecture is discussed as well as the modern digital monitoring receiver.   

  4. Pre-5G-NR Signal Generation And Analysis

    This application note offers instruction on how to use Rohde & Schwarz signal generators and analyzers for testing early 5G New Radio components, chipsets, and devices. These solutions provide a single user interface for signal generation and analysis configuration, flexible OFDM configuration, and user defined modulation schemes including complex scenarios.

  5. dB Or Not db? Everything You Need To Know About Decibels But Were Afraid To Ask

    What is a decibel and how should we use it in our calculations? Many calculations using decibels leave even experienced engineers scratching their heads. This application note is intended as a refresher on the subject of decibels.

  6. How To Avoid Pitfalls When Designing And Manufacturing An RF Automated Test Equipment System

    Automated test equipment (ATE) system development and manufacturing is a difficult job for many design teams. However, most of the issues that cause stress and delays can be avoided if they are identified and addressed long before a program begins.

  7. Modulation Accuracy Measurements Of DVB-S2 And DVB-S2X Signals

    This Rohde & Schwarz application note provides an overview on how signals with two different modulation schemes can be analyzed with a focus on DVB-S2(X) signals. It also covers a software tool that is used to automate the configuration and provide the variety of constellations used in DVB-S2(X).

  8. Ten Cues You Need A 5G MIMO Channel Modeler

    How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.

  9. Antenna Factor Concepts

    An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. This white paper explains the process of creating AF data and how to use it.

  10. Shielding Effectiveness Test Guide

    Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.
