TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

Voltage Standing Wave Ratio (VSWR) Explained
Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.
Transmit And Receive Testing Of Digital Waveforms Using R&S®CMA180
The compact R&S®CMA180 Radio Test Set allows straightforward tests on devices that use analog or digital modulation and demodulation formats. This application note focuses on the use of the digital radio capabilities for measurements on radio transceiving devices in terms of their functionality and parameter characterization. Also shown is how to use the instrument with the various software tools available from Rohde & Schwarz for creating and evaluating digitally modulated signals.
Design Of A Complete RF Downconverter Module For Test Equipment
The example module and its constituent parts were designed and simulated with AWR Design Environment software using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks.
Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation
This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.
Solution For BCI Applications
Rohde & Schwarz provides a compact solution for conducted immunity tests with a signal generator, RF solid-state amplifier up to 350 W, power sensors, and test software for frequencies from 4 kHz to 400 MHz.
