Selecting an RF power amplifier for EMC testing starts with the required test field, not with the highest wattage available. In a radiated immunity system,
Selecting an RF power amplifier for EMC testing starts with the required test field, not with the highest wattage available. In a radiated immunity system,
Radiated immunity testing is designed to verify whether electronic equipment can continue operating correctly when exposed to radio-frequency electromagnetic fields. The RF signal generator creates
Power-frequency magnetic fields are present in almost every electrical environment. Transformers, switchgear, motors, generators, power distribution cabinets, busbars, and high-current cables all generate low-frequency magnetic
A Coupling/Decoupling Network (CDN) is one of the most important devices used in EMC immunity testing. It enables RF disturbance signals to be injected into
Accurate EMC antenna measurements depend on more than the antenna specification printed on a datasheet. A calibrated antenna can still produce inconsistent radiated emissions results
Low-frequency electromagnetic disturbances are often dominated by magnetic fields generated by current flowing through power cables, switching circuits, transformers, motors, lighting equipment, and other electrical
Radiated EMC testing may require measurements from tens of megahertz to several gigahertz. A traditional setup often uses several antennas to cover this range, such
Dual-ridged horn antennas are widely used in EMC laboratories when radiated emissions or radiated immunity tests extend into the GHz range. Compared with conventional horn
In radiated EMC testing, the highest emission level is rarely found by placing the equipment under test in one fixed position and taking a single
Selecting an EMC antenna is not simply a matter of finding a model whose published frequency range covers the required test band. Two antennas may
A Line Impedance Stabilization Network (LISN) is one of the most important pieces of equipment used in EMC testing. It provides a standardized impedance between
Electronic products are often exposed to radio-frequency (RF) disturbances through power cables, signal lines, communication interfaces, and grounding systems rather than through the air. These
