Product Information:
The Coaxial Shielding Effectiveness Testing Device is designed in accordance with the requirements of GB/T 30412-2013. The high-precision machined coaxial flange components exhibit extremely low Voltage Standing Wave Ratio (VSWR) and minimal insertion loss across the testing frequency range, effectively ensuring the authenticity and accuracy of test results. The testing device is fully electroplated, which not only guarantees excellent performance but also provides durability and an aesthetically pleasing appearance.
Purpose
This device is suitable for measuring the plane-wave shielding effectiveness of planar electromagnetic shielding materials such as shielding fabrics, metal foils, coatings or platings on non-conductive materials, metal meshes, conductive films, conductive glass, and conductive dielectric plates. It fully complies with the requirements of GB/T 30142-2013 and is also applicable with reference to GJB 6190-2008. GB/T 25471-2010. and ASTM D4935-2018 (replacing ASTM D4935-2010) standards.
