Radiated Emissions (10m Method)

10m Semi-Anechoic Chamber Testing is a key facility used for Electromagnetic Compatibility (EMC) assessments. It is primarily utilized to measure the radiated emissions and immunity of electronic equipment at a distance of 10 meters. These tests are typically conducted in shielded semi-anechoic chambers compliant with international standards such as CISPR, FCC, and EN, ensuring accuracy and repeatability of test results.

Key Features:

1. 10-Meter Distance: Testing is conducted at a 10-meter range, suitable for larger equipment or applications requiring higher accuracy.

2. Shielded Semi-Anechoic Chamber: The chamber is lined with RF absorbers to minimize external electromagnetic interference and internal reflections, ensuring a clean testing environment.

3. radiated emission testing: Measures the electromagnetic radiation emitted during equipment operation to ensure it stays within regulatory limits.

4. Immunity Testing: Evaluates the equipment's performance under external electromagnetic interference to verify operational stability.

Application Fields:

- Consumer Electronics: Mobile phones, computers, home appliances, etc.

- Automotive Electronics: In-vehicle entertainment systems, navigation units, etc.

- Industrial Equipment: PLCs, inverters, robots, etc.

- Medical Devices: MRI systems, X-ray machines, patient monitors, etc.
