Continuous-Wave Propagation Channel-Sounding Measurement System - Testing, Verification, and Measurements

Abstract: In situ measurements of radio frequency (RF) spectrum activity provide insight into the physics of radio frequency wave propagation and validate existing and new spectrum propagation models. Both of these parameters are essential to supporting and preserving interference-free spectrum sharing, as spectrum use continues to increase. Verifying and validating a measurement system prior to making these types of important measurements is critical. This video article describes and illustrates the setup, validation and verification, and results from propagation measurements using a continuous-wave, radio frequency channel-sounding measurement system. ITS has used the technique shown here to validate other measurement systems so that the measurements are consistent. This protocol does not address electromagnetic interference or electromagnetic compatibility issues which can appear when multiple pieces of equipment are placed near each other.
