Because of skin effect, RF currents can't typically travel through metal walls ... of blindly accepting measurements and draw significant conclusions from them. Near-field measurements are easily ...

You may need to experiment with design modifications and repeated near-field measurements to get to the heart of the problem. Tim Dwyer, EMC program manager at TUV Rheinland (Newtown, CT; ...

Distinguishing between near field and far field conditions is ... The far field corresponds to an RF source-to-measurement antenna distance (r) great enough that energy radiates from the source ...

The sampled near field is then transformed into a far field using very accurate algorithms based on spherical wave expansion. The spherical geometry used for sampling is the most versatile and allows ...

The output power of an RF or microwave system is a key determinant ... to maintenance in the field. It is important that power measurements can be repeatable, which demands instruments offering a ...

Founded in Santa Rosa, CA in 2004 by two microwave engineers with a passion for quality microwave test instrumentation, LadyBug Technologies stands at the forefront of RF power measurement. Since its ...

Making off-air frequency measurements of AM broadcast stations ... I use the following complement of equipment: Field intensity meter (such as PI FIM-21/41, RCA WX-2 or Nems-Clarke 120); RF signal ...

Driven by the tracking-generator output of a spectrum analyzer, they provide the increased RF power outputs required ... are suitable for driving TekBox near-field probes in order to detect ...
