3-Meter EMC Anechoic Chamber

3-Meter Anechoic Chamber

I. Applications

1. This 3-meter anechoic chamber is a newly designed EMC test site primarily used for standard testing of radiated emissions and radiation susceptibility. The entire system is multi-functional, covering international, European, American, and national standards.

2. This site can test telecommunications equipment, household appliances, automotive components, industrial, medical, and electronic equipment (ISM), and information technology equipment (ITE) within a 3-meter testing distance.

3. The 3-meter anechoic chamber is also accredited by FCC facilities, European accreditation, and VCC1 recognition.

4. This anechoic chamber fully complies with general standards, and its frequency range can be extended to 18 GHz.

5. Utilizing a state-of-the-art modular system for shielding and absorbing materials, the installed anechoic chamber can be dismantled, reinstalled, or expanded to adapt to new standards.

II. Emission

1. For standard testing, radiated emission testing during the R&D phase and quality control is perfectly adequate in a 3-meter anechoic chamber. It complies with EN 50147-21996 and ANSI C63.41992 standards and has a 2.0-meter diameter quiet zone.

2. Alternatively, this 3-meter anechoic chamber can be upgraded to a frequency range up to 18 GHz.

III. Immunity
This 3-meter anechoic chamber also exhibits superior performance in radiated immunity testing. Within a 1.5 × 1.5 meter plane, a 3-meter test distance accurately meets IEC 1000-4-31995 and EN 61000-4-31996 standards.

IV. Radiated Emissions

1. According to EN 50147-21996 and ANSI C63.41992, the quiet zone performance at a test distance of 3 meters and a diameter of 2.0 meters achieves +/-4 dB.

2. Typical calibration data for normalized site attenuation across the frequency range. Horizontal and vertical polarization can be verified at a measurement distance of 3 meters.

V. Radiated Sensitivity
Accurately meets IEC 1000-4-31995 and EN 61000-4-31996 standards, requiring 75% accuracy of 16 points within 0…+6 dB at a test distance of 3 meters on a 1.5×1.5 meter plane.

VI. Technical Specifications

1. Anechoic chamber dimensions: Approximately 9.2*6.0*6.2 meters (length x width x height). 2. Control room enclosure dimensions: 4.0*3.0*3.0 meters / Amplifier room enclosure dimensions: 2.0*3.0*3.0 meters (dimensions can be adjusted according to site conditions)

3. Shielding performance: 9kHz≥70dB, 150kHz≥90dB, 200kHz-50MHz≥100dB, 50MHz-1GHz≥100dB, 1GHz-18GHz≥95dB.
