EMC testing becomes mechanically more demanding when the equipment under test is large, heavy, irregularly shaped, or connected to long cables and auxiliary equipment. This
Radiated emission testing is not a measurement taken from one fixed EUT position and one fixed antenna height. Electronic equipment rarely radiates electromagnetic energy equally
In EMC emissions testing, the antenna and EMI receiver are only part of the measurement chain. The RF cable, connectors, adapters, and preamplifier between them
An EMC radiated immunity system may need to generate controlled RF fields from tens of megahertz to several gigahertz. One of the main design decisions
Insufficient RF amplifier power is a common reason why a radiated immunity test system cannot achieve the required electric field strength. The problem is not
In radiated immunity testing, the electric field applied to the equipment under test is not determined by RF amplifier power alone. The achievable field strength
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
