TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• How To Test USB Power Delivery Over Type-C

  USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.

• Testing For Coexistence In Crowded And Contested RF Environments

  In this paper, we review some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.

• Accurate Test Fixture Characterization And De-Embedding

  This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.

• Circuit Models For Plastic Packaged Microwave Diodes

  This paper reports on the measurement and establishment of circuit models for SOT-23 and SOD-323 packaged diodes. Results indicate that the 1.5 nH estimate for the SOT-23 is a useful result, as is 1.2 nH for SOD-323 single packaged diodes. It was also determined that the effective inductance of the SOT-23 may be reduced to approximately 0.4 nH by adding a second bond wire and modifying the microstrip line. Other lead configurations, including parallel bond wires and common cathode configurations, were also studied.
