Shield Effect Measurement kit
Vinstronics’ Shield Effect Measurement kit is a tool specifically designed for electromagnetic compatibility (EMC) testing, capable of accurately measuring the shielding performance of electric quantities and connectors caused by coupling impedance and shielding attenuation.
The Shield Effect Measurement kit is a tool specifically designed for measuring the effectiveness of electromagnetic shielding materials and radio frequency cable assemblies. It is an essential piece of equipment in the testing and certification process of electronic products, ensuring that various electrical and electronic devices and systems can operate normally and without interference within the same electromagnetic environment.
Vinstronics’ triaxial shielding measurement can simultaneously test shielding attenuation, transfer impedance, and coupling attenuation. It can accurately measure the radio frequency electrical quantities and connector shielding performance caused by coupling impedance and shielding attenuation, with reference to the standard IEC 62153-4-X.
