Figure 1 – MVG COMOSAR Dosimetric E field Dipole Probe Length 330 mm Length of Individual Dipoles 2 mm Maximum external diameter 8 mm Probe Tip External Diameter 2.5 mm Distance between dipoles / probe extremity 1 mm 3 MEASUREMENT METHOD The IEEE 1528, FCC KDB865664 D01, CENELEC EN62209 and CEI/IEC 62209 standards provide recommended practices for the probe calibrations, including the performance characteristics of interest and methods by which to assess their affect. All calibrations / measurements performed meet the fore mentioned standards. 3.1 LINEARITY The evaluation of the linearity was done in free space using the waveguide, performing a power sweep to cover the SAR range 0.01W/kg to 100W/kg.
