3            PRODUCT DESCRIPTION

3.1     GENERAL INFORMATION
MVG’s COMOSAR Validation Dipoles are built in accordance to the IEEE 1528, FCC KDBs and
CEI/IEC 62209 standards. The product is designed for use with the COMOSAR test bench only.

                        SAR REFERENCE DIPOLE CALIBRATION REPORT                                                     Ref: ACR.189.3.16.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.
                     Scan Volume                    Expanded Uncertainty

       7     VALIDATION MEASUREMENT
The IEEE Std. 1528, FCC KDBs and CEI/IEC 62209 standards state that the system validation
measurements must be performed using a reference dipole meeting the fore mentioned return loss
and mechanical dimension requirements. 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.

        7.2    SAR MEASUREMENT RESULT WITH HEAD LIQUID
The IEEE Std. 1528 and CEI/IEC 62209 standards state that the system validation measurements
should produce the SAR values shown below (for phantom thickness of 2 mm), within the
uncertainty for the system validation. All SAR values are normalized to 1 W forward power. In
bracket, the measured SAR is given with the used input power.
