EMC/EMI Testing, Support, and Certification Services
Working closely with health and safety organizations, the FCC and other spectrum authorities around the world have adopted limits for exposure to radio frequency (RF) energy. For devices used closer than 20 cm to the head or body, the RF exposure limits are given in terms of the Specific Absorption Rate (SAR), which is a measure of radio frequency energy absorbed by the head or body. As part of the equipment authorization process, manufacturers are required to ensure that their devices comply with these limits for exposure. The FCC and Industry Canada limit for public exposure is a SAR level of 1.6 watts per kilogram (1.6 W/kg). The European Union and many other countries have a SAR limit of 2.0 W/kg.
Our SAR Testing lab is located in a semi-anechoic chamber to maintain strict temperature control and eliminate influences from other nearby transmitters. We’ve selected the premier supplier of SAR evaluation systems and government-preferred vendor, SPEAG of Zurich Switzerland, to provide their latest offering – the DASY5. Equipped with probes, tissue simulants, and phantoms, the DASY5 can evaluate wireless devices operating from 400 MHz – 6 GHz. In addition, we use the R&S CMU200 to support all cellular operating modes up through EVDO and HSPA Rel. 6.
