EMF Exposure Systems
sXcTEM835
sXcTEM835
Tests radiofrequency electromagnetic field exposures from mobile communication devices operating in the 900 MHz region (additional frequencies upon request). The setup is based on two Crawford TEM cells that are blindly excited by a fully computer-controlled signal unit.
