Main Components of a Semi-Anechoic Chamber
A semi-anechoic chamber is more than a shielded room covered with RF absorber. It is a complete EMC test environment
Key Anechoic Chamber Performance Indicators: NSA, SVSWR, and Field Uniformity
An anechoic chamber can have excellent shielding effectiveness and still produce inaccurate EMC test results if its internal electromagnetic environment
Positioning System Requirements for Large Equipment and UAV EMC Testing
EMC testing becomes mechanically more demanding when the equipment under test is large, heavy, irregularly shaped, or connected to long
Why EUT Rotation and Antenna Height Scanning Matter in Radiated Emission Testing
Radiated emission testing is not a measurement taken from one fixed EUT position and one fixed antenna height. Electronic equipment
How RF Cables, Connectors, and Preamplifiers Affect EMC Test Results
In EMC emissions testing, the antenna and EMI receiver are only part of the measurement chain. The RF cable, connectors,
Broadband vs. Multi-Band Amplifiers for EMC Immunity Systems
An EMC radiated immunity system may need to generate controlled RF fields from tens of megahertz to several gigahertz. One
Common Signs of Insufficient RF Amplifier Power in EMC Testing
Insufficient RF amplifier power is a common reason why a radiated immunity test system cannot achieve the required electric field
How Amplifier Power, Antenna Gain, and Test Distance Determine Field Strength
In radiated immunity testing, the electric field applied to the equipment under test is not determined by RF amplifier power
