  1. Demystifying Over-The-Air Testing – Important Antenna Parameters, Test System Setup, And Calibration

    The step from conducted measurements to OTA testing changes the measurement requirements to a certain degree, so users must have a basic understanding of antennas and antenna measurements.

  2. Reliable And Flexible Simulation Of Angle Of Arrival (AoA)

    The purpose of radar warning equipment is to detect, measure, and identify radar signals to provide a warning so available countermeasures can be taken. It is also mandatory to have direction finding (DF) capabilities to identify the angle of arrival (AoA) of a signal. It is highly desirable that engineers have a simulator that can provide test signals for simulating the AoA. This white paper presents a solution from Rohde & Schwarz designed to meet the challenges associated with simulating the AoA of radar signals.

  3. Choosing The Right Route To Low-Power Cellular IoT: User Guide To Simplifying LTE-M/NB-IoT Design Projects

    Cellular transformation is underway in the medical and industrial space with the push for low-power cellular networks such as LTE CAT-M1 and NB-IoT. These technologies are unleashing a new wave of IoT devices that drastically reduce cost and operate for years on a single battery. But that’s just the start. Combining low-power cellular with Bluetooth 5 offers two best-in-class wireless technologies to bridge local sensors, phones, people, gateways, and the cloud into one seamless extension.

  4. 3 Series MDO Spectrum Analyzer Vs. Oscilloscope FFT Comparison

    Mixed Domain Oscilloscopes (MDO) have built-in spectrum analyzers with an RF input ideal for significantly higher dynamic ranges, versus an oscilloscope using a regular input and an FFT function. 

  5. 4 Tips For 5G New Radio Signal Creation

    Working with 5G New Radio (NR) technologies requires dealing with millimeter-wave (mmWave) frequencies, wide channel bandwidths, and complex multi-antenna configurations. To properly simulate 5G NR compliant signals for testing transmitters and receivers of base stations, metrology-grade reference signals are required to see the true characteristics of the device under test (DUT). This white paper outlines the steps to get started on the next phase of the 5G rollout. Insights include tips on how to create and evaluate 5G NR signals, and what to watch for during design validation.
