NTEKJL:JJ*=« KA Certificate #4298.01 ~ SAR REFERENCE DIPOLE CALIBRATION REPORT Ref: ACR.109.7.18.SATUA 4 MEASUREMENT METHOD The IEEE 1528, FCC KDBs and CELMIEC 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 RETURNLOSS 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 phantomconstructed as outlined in the fore mentioned standards. 4.2 MECHANICAL REQUIREMENTS The IEEE Std. 1528 and CEIMIEC 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 phantomshell 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 RETURNLOSS 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 53 VALIDATION MEASUREMENT The guidelines outlined in the IEEE 1528, FCC KDBs, CENELEC ENSO361 and CELIEC 62209 standards were followed to generate the measurement uncertainty for validation measurements.

NTEKJE:WJ KA Certificate #4298.01 _ SAR REFERENCE DIPOLE CALIBRATION REPORT Ref: ACR.109.8.18.SATUA 4 MEASUREMENT METHOD The IEEE 1528, FCC KDBs and CELMIEC 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 RETURNLOSS 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 phantomconstructed as outlined in the fore mentioned standards. 4.2 MECHANICAL REQUIREMENTS The IEEE Std. 1528 and CEIMIEC 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 phantomshell 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 RETURNLOSS 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 53 VALIDATION MEASUREMENT The guidelines outlined in the IEEE 1528, FCC KDBs, CENELEC ENSO361 and CELIEC 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 dimensionof the flat phantom, with the top surface of the dipole at the described distance fromthe bottomsurface of the phantom. 7.1 HEAD LIQUID MEASUREMENT Fre:fll:le:cy Relative permittivity (€)‘) Conductivity (0) S/m required measured required measured 300 45.3 15 % 0.87 15 % 450 43.5 15 % 0.87 15 % 750 41.9 25 % 0.89 15 % 835 41.5 25 % 0.90 25 % 900 41.5 45 % 0.97 15 % 1450 40.5 +5 % 1.20 45 % 1500 40.4 15 % 123 15% 1640 40.2 25 % 131 +5 % 1750 40.1 +5 % 1.37 +5 % Page: 7/11 This document shall not be reproduced, except infull orin part, withoutthe written approval ofMVG.
