TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• R&S®FSWP And The Validity Of Positive Phase Noise Values

  This white paper reviews the classical spectrum analyzer measurement of L(f) and its shortcomings. It also discusses how modern phase noise test sets measure phase noise and avoid the limitations imposed by direct spectrum measurements, especially with the use of the R&S®FSWP.

• 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.

• 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.

• Power Supply Control Loop Response Measurements (Bode Plot)

  The R&S^® RTx-K36 frequency response analysis (Bode plot) option provides a low-cost alternative to low frequency network analyzers or dedicated standalone frequency analyzers. 

• VCO Measurements With FSPN Phase Noise Analyzer

  This application note provides a short technical introduction to voltage-controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.
