COMOSAR E-FIELD PROBE CALIBRATION REPORT Ref: ACR.189.1.16.SATU.A 1 DEVICE UNDER TEST Device Under Test Device Type COMOSAR DOSIMETRIC E FIELD PROBE Manufacturer MVG Model SSE5 Serial Number SN 37/08 EP80 Product Condition (new / used) Used Frequency Range of Probe 0.7 GHz-3GHz Resistance of Three Dipoles at Connector Dipole 1: R1=1.445 M Dipole 2: R2=1.467 M Dipole 3: R3=1.477 M A yearly calibration interval is recommended. 2 PRODUCT DESCRIPTION 2.1 GENERAL INFORMATION MVG’s COMOSAR E field Probes are built in accordance to the IEEE 1528, OET 65 Bulletin C and CEI/IEC 62209 standards. 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.189.1.16.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.
