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.

• 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.

• 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.
