The Fabric anti-electromagnetic radiation performance tester is an advanced, highly precise testing device designed to measure the shielding effectiveness of various textiles, metal sheets, plastic cloth, and non-conductive metal surface coating against electromagnetic radiation. The fabric sample is placed using the automatic clamping system inside the controlled electromagnetic chamber. The device releases electromagnetic waves at different frequencies that pass through the sample fabric. The difference between these signals determines the shielding effectiveness of the fabric.

Key Features

Precision testing method: The tester uses a flange coaxial method to measure how much a material can block electromagnetic radiations and ensure consistent and accurate testing results.

Compound network for detecting signals: This electromagnetic shielding efficiency tester has a network analyzer that measures the transmission and reflection parameters by analyzing how signals pass through and reflect through the sample fabric.

Advanced digital technology: The tester contains a highly precise DDS (Direct Digital Synthesis) signal source with a narrow-band receiver that generates accurate frequency radiation. It also has DSP (Digital Signal Processing) technology and a high-speed processor for accurate real-time data processing.

Comprehensive testing ability: The device does full-frequency scanning to analyze a wide spectrum of shielding performance.

User-friendly operation: This radiation detector performance tester has intuitive PC software for synchronized parameter settings and automatic data processing, which is quick and reliable for testing operations
