TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• RF Test Setup For Measuring Power & Harmonics

  Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

• 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.

• Characterization Of An Amplifier With The Combination Of Network And Spectrum Analysis

  The general characterization of complex DUTs such as amplifiers requires the measurement of several parameters. Thanks to its versatility, the R&S^® ZNL is an economic solution that can characterize a variety of DUTs both via network analysis and spectrum analysis.

• Electronic Packaging: Using EMI Material-Based Solutions

  It can be difficult when individual components could pass EMI testing but, as the components are combined into subsystems or into the final product, the DUT fails. Incorporating EMI shielding materials as part of an initial design is the most cost-effective way to prevent these last-minute issues during testing.
