TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• 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.

• Qorvo Biotechnologies Sensor-Based Technology Provides Rapid Reference-Lab Quality Tests At Point-of-Care

  This white paper describes Qorvo Biotechnologies’ Bulk Acoustic Wave (BAW) immunosensor detection platform designed for point-of-care applications and describes analytical and functional sensitivity testing on human Thyroid Stimulating Hormone (hTSH) as an example. The Qorvo Biotechnologies’ platform is targeted to be central lab matched, with the goal of providing clinicians data that will enable quicker decision making across multiple disease states, such as in cardiac and infectious disease segments, where time to result and high performance are critical factors in the patient care workflow.

• Crowdsourcing Versus Mobile Network Testing

  The need for an objective evaluation of mobile network quality and performance drives two fundamentally different approaches, crowdsourcing, and mobile network testing.

• An Introduction To Direction Finding Methodologies

  All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.
