® A\G & T I & m Attestation of Global Compliance uo mvG SAR REFERENCE DIPOLE CALIBRATION REPORT Ref: ACR.69.2.17.SATU.A 4 MEASUREMENT METHOD The IEEE 1528, FCC KDBs and CEIIEC 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. § 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 CEUIEC 62209 standards were followed to generate the measurement uncertainty for validation measurements.
