Figure 1 ± MVG COMOSAR Dosimetric E field Dipole Probe Length 330 mm Length of Individual Dipoles 4.5 mm Maximum external diameter 8 mm Probe Tip External Diameter 5 mm Distance between dipoles / probe extremity 2.7 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.154.4.15.SATU.A 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 box illuminated with the fields from a half wave dipole. The dipole is rotated about its axis (0°±180°) in 15° increments. At each step the probe is rotated about its axis (0°±360°). 3.5 BOUNDARY EFFECT The boundary effect is defined as the deviation between the SAR measured data and the expected exponential decay in the liquid when the probe is oriented normal to the interface. To evaluate this effect, the liquid filled flat phantom is exposed to fields from either a reference dipole or waveguide. With the probe normal to the phantom surface, the peak spatial average SAR is measured and compared to the analytical value at the surface. 4 MEASUREMENT UNCERTAINTY The guidelines outlined in the IEEE 1528, OET 65 Bulletin C, CENELEC EN50361 and CEI/IEC 62209 standards were followed to generate the measurement uncertainty associated with an E-field probe calibration using the waveguide technique. All uncertainties listed below represent an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2, traceable to the Internationally Accepted Guides to Measurement Uncertainty.

SAR REFERENCE DIPOLE CALIBRATION REPORT Ref: ACR.75.4.15.SATU.A 4 MEASUREMENT METHOD The IEEE 1528, FCC KDBs and CEI/IEC 62209 standards provide requirements for reference dipoles used for system validation measurements. The following measurements were performed to verify that the product complies with the fore mentioned standards. 4.1 RETURN LOSS REQUIREMENTS The dipole used for SAR system validation measurements and checks must have a return loss of -20 dB or better. The return loss measurement shall be performed against a liquid filled flat phantom, with the phantom constucted as outlined in the fore mentioned standards. 4.2 MECHANICAL REQUIREMENTS The IEEE Std. 1528 and CEI/IEC 62209 standards specify the mechanical components and dimensions of the validation dipoles, with the dimensions frequency and phantom shell thickness dependent. The COMOSAR test bench employs a 2 mm phantom shell thickness therefore the dipoles sold for use with the COMOSAR test bench comply with the requirements set forth for a 2 mm phantom shell thickness. 5 MEASUREMENT UNCERTAINTY All uncertainties listed below represent an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2, traceable to the Internationally Accepted Guides to Measurement Uncertainty. 5.1 RETURN LOSS The following uncertainties apply to the return loss measurement: Frequency band Expanded Uncertainty on Return Loss 400-6000MHz 0.1 dB 5.2 DIMENSION MEASUREMENT The following uncertainties apply to the dimension measurements: Length (mm) Expanded Uncertainty on Length 3 - 300 0.05 mm 5.3 VALIDATION MEASUREMENT The guidelines outlined in the IEEE 1528, FCC KDBs, CENELEC EN50361 and CEI/IEC 62209 standards were followed to generate the measurement uncertainty for validation measurements.

The validation measurement must be performed against a liquid filled flat phantom, with the phantom constructed as outlined in the fore mentioned standards. Per the standards, the dipole shall be positioned below the bottom of the phantom, with the dipole length centered and parallel to the longest dimension of the flat phantom, with the top surface of the dipole at the described distance from the bottom surface of the phantom. 7.1 HEAD LIQUID MEASUREMENT Frequency Relative permittivity (r’) Conductivity (σ) S/m MHz required measured required measured 300 45.3 ±5 % 0.87 ±5 % 450 43.5 ±5 % 0.87 ±5 % 750 41.9 ±5 % 0.89 ±5 % 835 41.5 ±5 % 0.90 ±5 % 900 41.5 ±5 % 0.97 ±5 % 1450 40.5 ±5 % 1.20 ±5 % 1500 40.4 ±5 % 1.23 ±5 % 1640 40.2 ±5 % 1.31 ±5 % 1750 40.1 ±5 % 1.37 ±5 % Page: 7/11 This document shall not be reproduced, except in full or in part, without the written approval of MVG.
