sXc1950

 

Designed to test radiofrequency electromagnetic field exposures from third generation (3G) mobile communication devices operating according to the UMTS standard. 2G modulation schemes such as GSM are also applicable. The setup is based on two R18 rectangular waveguide chambers that are blindly excited by a fully computer-controlled signal unit.
