Semi Anechoic Chambers for EMC testing
EMC Semi Anechoic Chambers are used while performing electromagnetic compatibility tests of equipments or systems. Most of the product standards require EMC testing to be done in RF isolated and absorber covered test chambers. If the floor of the anechoic chamber is ground, we call it semi anechoic chamber. Becasue not all of the six surfaces are covered by RF absorbers. Instead, 5 surfaces is covered by RF absorbers.
Semi Anechoic Chambers used for electromagnetic compatibility emissions and immunity tests are categorized according their far field measurement distance:
3 meter Semi Anechoic Chamber (SAC)
5 meter Semi Anechoic Chamber (SAC)
10 meter Semi Anechoic Chameber (SAC)
30 meter Semi Anechoic Chamber (SAC)
Measurement distance is essential to define the semi anechoic chamber’s dimensions. For a 3 meter SAC the most used and recommended dimensions are 9x6x6m (LXWXH).
