Questions to Ask Before Purchasing a TEM Cell or GTEM Cell

When it comes to conducting electromagnetic compatibility (EMC) testing, TEM (Transverse ElectroMagnetic) cells and GTEM (GigaHertz Transverse ElectroMagnetic) cells are widely used for their ability to generate controlled and repeatable test environments.

The Importance of Antenna Beamwidth in RF Testing

Antenna beamwidth determines the expected signal strength given the direction and radiation distance of an antenna. The beamwidth will vary given a number of different factors such as the antenna type, design, orientation, and radio frequency. Understanding beamwidth and how it influences a test environment is critical to accurate and repeatable tests.

Application of Thrifty Test Equipment for EMC Testing

EMC testing laboratories often have limitations (limited availability, lead times, etc.) that can make it difficult to obtain timely results from routine troubleshooting. Inexpensive test equipment can support efficient and economical in-house EMC troubleshooting.

Trust but Verify

It’s imperative for successful completion of a testing project that as a compliance engineer or technician leading a product certification effort, you trust but verify the work of testing facilities.

Dipole-Type Antennas in EMC Testing

This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna. Part I presents the antenna models and the construction details.
