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, OET 65 Bulletin C, CENELEC EN50361 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. COMOSAR E-FIELD PROBE CALIBRATION REPORT Ref: ACR.233.1.17.SATU.A Page: 5/10 This document shall not be reproduced, except in full or in part, without the written approval of MVG. The information contained herein is to be used only for the purpose for which it is submitted and is not to be released in whole or part without written approval of MVG. 3.2 SENSITIVITY The sensitivity factors of the three dipoles were determined using a two step calibration method (air and tissue simulating liquid) using waveguides as outlined in the standards. 3.3 LOWER DETECTION LIMIT The lower detection limit was assessed using the same measurement set up as used for the linearity measurement. The required lower detection limit is 10 mW/kg. 3.4 ISOTROPY The axial isotropy was evaluated by exposing the probe to a reference wave from a standard dipole with the dipole mounted under the flat phantom in the test configuration suggested for system validations and checks. The probe was rotated along its main axis from 0 - 360 degrees in 15 degree steps. The hemispherical isotropy is determined by inserting the probe in a thin plastic box filled with tissue-equivalent liquid, with the plastic …
