Figure 1 MVG COMOSAR Dosimetric E field Probe Probe Length Length of Individual Dipoles Maximum external diameter Probe Tip External Diameter Distance between dipoles / probe extremity 330 mm 2 mm 8 mm 2.5 mm 1 mm 3 MEASUREMENT METHOD The IEC/IEEE 62209-1528 and FCC KDB865664 D01 standards provide recommended practices for the probe calibrations, including the performance characteristics of interest and methods by which to assess their effect. All calibrations / measurements performed meet the fore-mentioned standards. 3.1 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 for frequency range 6007500MHz and using the calorimeter cell method (transfer method) as outlined in the standards for frequency 150-450 MHz.

COMOSAR E-FIELD PROBE CALIBRATION REPORT Ref: ACR.193.11.24.BES.B 3.2 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. 3.3 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 to 360 degrees in 15degree 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°). 3.4 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. The boundary effect uncertainty can be estimated according to the following uncertainty approximation formula based on linear and exponential extrapolations between the surface and dbe + dstep along lines that are approximately normal to the surface: where SARuncertainty dbe step SARbe is the uncertainty in percent of the probe boundary effect is the distance between the surface and the closest zoom-scan measurement point, in millimetre is the separation distance between the first and second measurement points that are closest to the phantom surface, in millimetre, assuming the boundary effect at the second location is negligible is the minimum penetration depth in millimetres of the head tissue-equivalent liquids defined in this standard, i.e., 14 mm at 3 GHz; in percent of SAR is the deviation between the measured SAR value, at the distance dbe from the boundary, and the analytical SAR value. The measured worst case boundary effect SARuncertainty[%] for scanning distances larger than 4mm is 1.0% Limit ,2%).

COMOSAR E-FIELD PROBE CALIBRATION REPORT Ref: ACR.193.11.24.BES.B 3.5 PROBE MODULATION RESPONSE MVG's probe were evaluated experimentally with various modulated signal and the deviation from CW response were found neglectable in the used power range of the probe. So the correction to taking into account the linearization parameters for different modulation is null, therefore the CW factor given in this report can be used whatever the measured modulation 4 MEASUREMENT UNCERTAINTY The guidelines outlined in the IEC/IEEE 62209-1528 and FCC KDB865664 D01 standards were followed to generate the measurement uncertainty associated with a SAR probe calibration using the waveguide or calorimetric cell technique depending on the frequency. The estimated expanded uncertainty (k=2) in calibration for SAR (W/kg) is +/-11% for the frequency range 150-450MHz. The estimated expanded uncertainty (k=2) in calibration for SAR (W/kg) is +/-14% for the frequency range 600-7500MHz. 5 CALIBRATION RESULTS Liquid Temperature Lab Temperature Lab Humidity Ambient condition 20 +/- 1 °C 20 +/- 1 °C 30-70 % 5.1 CALIBRATION IN AIR The following curve represents the measurement in waveguide of the voltage picked up by the probe toward the E-field generated inside the waveguide.

SAR REFERENCE DIPOLE CALIBRATION REPORT Ref: ACR.104.1.23.SATU.A 4 MEASUREMENT METHOD The IEC/IEEE 62209-1528 and FCC KDB865664 D01 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 constructed as outlined in the fore mentioned standards. A direct method is used with a network analyser and its calibration kit, both with a valid ISO17025 calibration. 4.2 MECHANICAL REQUIREMENTS The IEC/IEEE 62209-1528 and FCC KDB865664 D01 standards specify the mechanical components and dimensions of the validation dipoles, with the dimension's 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. A direct method is used with a ISO17025 calibrated caliper. 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 0.08 LIN 5.2 DIMENSION MEASUREMENT The following uncertainties apply to the dimension measurements: Length (mm) Expanded Uncertainty on Length 0 - 300 0.20 mm 300 - 450 0.44 mm 5.3 VALIDATION MEASUREMENT The guidelines outlined in the IEC/IEEE 62209-1528 and FCC KDB865664 D01 standards were followed to generate the measurement uncertainty for validation measurements.

Extended Calibration SAR Dipole Referring to KDB865664 D01, if dipoles are verified in return loss (<-20dBm, within 20% of prior calibration), and in impedance (within 5 ohm of prior calibration), the annual calibration is not necessary and the calibration interval can be extended. Justification of Extended Calibration SAR Dipole SID2450 serial no.

Therefore the value result should support extended.
