TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• 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.

• Power Consumption Analysis With Specialty DC Power Supplies

  Optimizing power consumption is critical for IoT devices running on small, non-rechargeable batteries. Learn how accurate characterization and smart design can extend device lifespans.

• 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.

• eUICC Profile Handling

  This application note describes the eUICC compliance and remote eUICC provisioning test solution based on R&S CMW500/CMW290 and COMPRION eUICC Profile Manager software tool with focus on M2M devices.
