TEST AND MEASUREMENT APPLICATION NOTES AND WHITE PAPERS
SCPI-Recorder: Test Automation At Your Fingertips
This application note briefly summarizes the history of SCPI and outlines in which fields of application a SCPI based test system software has still advantages over a driver (e.g. IVI) based approach.
Optimize Beamforming: From Bits To RF Beams
To achieve accurate, reliable and efficient beamforming, it is necessary to understand and compensate for the nonlinear behavior of RF components. This app note covers the benefits of Rohde & Schwarz’s portfolio of conducted and OTA test solutions and how they help to optimize beamforming.
Measurement Of Harmonics Using Spectrum Analyzers
This Application Note focuses on measurement of harmonics using modern spectrum analyzers and highlights the source of harmonics before focusing on their measurement using a spectrum analyzer.
Millimeter-wave Intermodulation Distortion (IMD) Measurements
This application note discusses the complications encountered in IMD measurements (set up complexity and hardware availability being the two main issues), and how Anritsu’s ME7838A family of broadband vector network analyzers (VNAs) can be used to make millimeter-wave measurements easier and more streamlined.
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.
