EMC Question of the Week: April 8, 2019

Normalized Site Attenuation Measurement

Normalized site attenuation measurements are performed to evaluate the integrity of

  1. semi-anechoic environments
  2. reverberation chambers 
  3. TEM and GTEM cells
  4. filters

Answer

The correct answer is "a." Site attenuation measurements effectively measure the transfer coefficient between a transmitting antenna and a receiving antenna at a given semi-anechoic test site. The measured value is compared to the theoretical transfer coefficient for an ideal semi-anechoic environment as a measure of the site quality.
