An anechoic chamber is a laboratory specifically designed for testing the electromagnetic compatibility (EMC) and radio frequency (RF) performance of electronic equipment. It effectively isolates external electromagnetic interference and provides a highly controlled testing environment.
Key Features :
Structure and Materials: Typically a sealed, metal-shielded space, internally covered with absorbing materials (such as polyurethane foam cones and ferrite tiles) to absorb electromagnetic waves and reduce reflections and multipath effects.
Types :
• Fully Anechoic Chamber: The floor, walls, and ceiling are all covered with absorbing materials, simulating a free-space environment. Shielding effectiveness can reach 80dB~140dB, suitable for emission, sensitivity, and immunity testing.
• Semi-Anechoic Chamber: The floor is a conductive reflector, and the other surfaces are covered with absorbing materials, simulating an open field, suitable for radiated interference testing.
Applications :
• EMC testing (radiated, conducted, immunity), RF testing, antenna performance evaluation.
• Radio frequency certification (FCC, CE, etc.), safety testing, environmental testing (waterproof, dustproof, etc.).
• Applicable to testing and certification of various products including electronics, automotive, aerospace, and medical devices.
Precise Equipment Support :
• Top-of-the-line testing instruments (spectrum analyzers, signal generators, turntables, etc.)
• Automated testing process, ensuring accurate and stable data.
Product Specifications and Services :
• Offers multiple size options (e.g., 3m, 5m, 10m testing distances), customizable to meet different site requirements.
• Modular structure for easy installation and maintenance, compliant with international standards.
• Offers testing equipment purchase, rental, and maintenance/calibration services.
