  1. Understanding And Testing Multi-Channel RF Systems With Signal Generators
    8/13/2019

    As the number of antennas grow in wireless systems, test complexity also increases. As a result, it is necessary to generate multiple RF channels for receiver testing and to analyze multiple RF channels for transmitter testing.

  2. Reimagining The Role Of Connectivity In Communications, Sensing, And Protection Of Ground Forces
    8/7/2019

    The U.S. and several NATO countries have been working on the seemingly impossible task of reducing size and weight of soldiers’ equipment while simultaneously increasing functionality and power. For engineers dealing with connectivity issues, this has brought about smaller and smaller connectors, cables and devices. Interconnected and portable devices have until now mainly been used by soldiers on covert operations. A wired tactical vest extends the concept of wearables beyond special forces by making the garments more modular, more accessible, and more affordable.

  3. NewSpace Terminal Testing Challenges And Considerations
    8/7/2019

    NewSpace networks and terminal vendors need to thoroughly test wireless communication systems and components to ensure uninterrupted operation and high quality of service. This white paper focuses primarily on the challenges ground terminals (user terminals and gateway terminals) present to design verification testing and manufacturing. Conducted and radiated test solutions are also discussed.

  4. Designing Microwave PCBs For Successful Manufacture — Getting It Right The First Time
    8/6/2019

    With improvements in processor speed and model accuracy, it is more common for microwave circuit simulations to bear close approximation to their eventual real-world performance. However, not all pitfalls present in the successful manufacture of a complex microwave circuit are captured in simulations. 

  5. EMC Pre-Compliance Fundamentals
    7/24/2019

    By using a performance EMI receiver, independent compliance test laboratories and companies with in-house self-certification labs can make radiated and conducted emissions tests, certifying a product meets local regulatory compliance standards. Learn how to make EMC pre-compliance measurements with this white paper.

  6. 3 Tactics For Configuring Phase-Coherent RF Signal Generation
    7/24/2019

    This white paper will help the reader understand phase coherence and why it matters, and offer tactics for generating phase-coherent signals.

  7. Glass Sidewall Packages Provide Performance For RF Applications
    7/19/2019

    Glass sidewall packages achieve highest levels of hermeticity for hardware in space vacuums and extreme temperatures. Compared to ceramic, they deliver better RF performance thanks to their lower dielectric constant.

  8. Highs And Lows Of Electronic Warfare
    7/18/2019

    The next chapter of electronic warfare is all about precision and low visibility. Col. Mark Dotson said the Army’s new EW strategy is centered on, “using low power to affect the signal and to affect it in such a way that it may not even be detectable that you’re interfering with what they’re doing.”

  9. 5G New Radio eBook
    7/18/2019

    Is 5G simply another generation of mobile communications technologies? Or something revolutionary? In this eBook, Rohde & Schwarz give insights into 5G New Radio (NR), exploring all of its relevant details, key implementation aspects, and required test and measurement equipment for the development of 5G NR products.

  10. The Wi-Fi 6 Revolution Wakeup Call For Your Test Strategy
    7/18/2019

    The IEEE 802.11ax amendment (Wi-Fi 6) focuses on greater efficiency in wireless connectivity. While key attributes of this improved efficiency directly improve traditional Wi-Fi applications, these attributes will largely affect higher-density applications such as large offices, apartment complexes, airports, arenas, and outdoor stadiums. This white paper offers several ideas of how to make Wi-Fi 6 a reality.
