In general, we consider the following types of chamber for removal: Pre-compliance EMC chambers (e.g. 20’x10’x10′ and larger) Semi-anechoic chambers for EMC and RF testing purposes. Fully compliant 3m, 5m and 10m chambers.An anechoic chamber is a room that has been acoustically tuned to have no reverberation, and no echo. Echoes and reverberation can alter sound significantly. To examen the acoustical properties of an object of interest, it is important to do so in a room free of echoes so as not to alter results.The Engineering Technology programs (ECET and MET) emphasize hands-on learning and practical aspects of engineering. Many engineering technology courses have laboratories and the laboratory experience is an integral part of the learning objectives. We offer ABET accredited undergraduate programs in Electrical and Computer Engineering Technology ... Distance of far field region is also depending on size of antenna aperture. High antenna gain for measured antenna increases size of near field region. Assume a parabolic antenna, 1 meter dia. and 10 GHz. 10*lambda is then 300mm but at that distance is it not any planar wave. In this case starts far field region maybe at 1000*lambda away.NTS boasts the most EMI/EMC chambers in North America.
