EMF Exposure Systems
sXh900/sXh2140
sXh900/sXh2140
The sXh900 and sXh2140 ex- posure systems are designed to perform human provocation studies in the GSM and UMTS mobile bands. They are based on patch antennas mounted on the side of the volunteer’s head. The antennas are covered with plastic boxes, such that the two systems are not visually distin- guishable.
