Semi-Anechoic Chamber 

EMERL houses a 10m Semi-Anechoic Chamber for emission measurements and susceptibility tests in compliance to EMC standards.  
 

 
Semi-Anechoic Chamber


Semi-anechoic chamber is catering to MIL-STD-461E, FCC and EN full compliance requirement for radiated and conducted emission. 

  • Physical dimension: 21m by 13m and 9m tall

  • Turntable: 4m diameter, withstand 30 tones of static load

  • Operating frequency: up to 40 GHz

The Semi-Anechoic Chamber is based on the modular design, it have the following shielding effectiveness:

Magnetic field

Electric Field

56 dB at 10KHz to 90dB at 100KHz

At least 100dB from 10KHz to 40GHz


The RAM (radar absorbing material) lining the walls and ceiling are moisture resistant and flame retardant having reflectivity of -25dB from 30MHz to 18GHz. Ferrite tiles with absorption of 19dB up to 800MHz and -10dB up to 1.5GHz were used.
