Near-field probe sets may include three sizes of H-field loop probes and one E-field contact probe. Courtesy of ETS-Lindgren. Near-field probes are useful tools for locationing the sources of ...

The field of antenna measurements has seen substantial advancements through the development of near-field to far-field (NF-FF) transformation techniques. These methods are vital for accurately ...

Electromagnetic interference (EMI) poses a significant challenge in modern electronic systems, where high-speed digital circuits and densely integrated components increasingly risk mutual disruption.

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical near-field antenna range. The 1,260-square-foot indoor range, lined with radio ...

EMI from on-board DC-DC converters is a common problem with IoT products. These small circuits generally switch between 1 MHz and 3 MHz and use very fast sub-nanosecond edge speeds. The result is ...

When Scotty is beaming up, he’s working in the very far field. Distinguishing between near field and far field conditions is especially important in EMC testing. Published antenna factors and related ...

Photon offers a line of NIST-traceable camera-based near-field profilers based on the 2/3-inch USBeamPro CMOS camera and the 1/2-inch and 2/3-inch FireWire CCD cameras. Photon Near Field Profilers: ...

Luminous intensity data is critical for lighting design, providing insight to the effect and appearance of lighting in a given environment. Captured in photometric data files, luminous intensity data ...

SwRI’s 1,260-square-foot indoor spherical near-field antenna range is equipped with a built-in overhead half-ton hoist to install and test large antennas up to 10 feet in diameter and 1,000 pounds.
