TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• Measurement Setup For Phase Noise Test At Frequencies Above 50 GHz

  Recent semiconductor technologies require more of the frequency range beyond 50 GHz, especially in wideband applications, such as 802.11ad, microwave links, or automotive RADAR. Low phase noise is essential for these applications to work properly, and accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise.

• Harmonic Measurement For IEC 61000-4-3 And Other Radiated Immunity Standards

  Amplifiers exhibiting significant harmonic distortion in immunity test systems can exhibit broadband characteristics that result in measurement uncertainty and unacceptable errors. This app note addresses acceptable harmonic measurement standards and other radiated immunity standards.

• 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.

• Test Automotive Radar Interference Mitigation

  Automotive radar is crucial for achieving Net Zero targets in the automobile industry, and the R&S AREG800A radar echo generator is essential for testing sensor immunity to interference.
