The impedance stated is transformed from the measurement at the SMA connector to the feed point. The Return Loss ensures low reflected power. No uncertainty required. Electrical Delay: One-way delay between the SMA connector and the antenna feed point No uncertainty required. SAR measured: SAR measured at the stated antenna input power. SAR normalized: SAR as measured, normalized to an input power of 1 Wat the antenna connector. SAR for nominal TSL parameters: The measured TSL parameters are used to calculate the nominal SAR result. The reported uncertainty of measurement is stated as the standard uncertainty of Measurement multiplied by the coverage factor k=2, which for a normal distribution Corresponds to a coverage probability of approximately 95% Certificate No: Z23-60014 Page 2 of 6 In Collabo rati on with CALIBRATION LABORATORY Add: No.51 Xueyuan Road, Haidian District, Beijing, I 00191, China Tel: +86-10-62304633-2079 Fax: +86-10-62304633-2504 E-mail: [email protected] http://www.chinattl.cn Measurement Conditions DASY system configuration, as fa DASY Version DASY52 V52.10.4 Extrapolation Advanced Extrapolation Phantom Triple Flat Phantom 5.1 C Distance Dipole Center - TSL 10 mm with Spacer Zoom Scan Resolution dx, dy, dz = 5 mm Frequency 2600 MHz土1MHz Head TSL parameters The fo Temperature Permittivity Conductivity Nominal Head TSL parameters 22.0 ° C 39.0 1.96 mho/m Measured Head TSL parameters (22 0士0.2) ° C 40.1士6% 1.95 mho/m士6% Head TSL temperature change during test <1.0 ° C －－－－ ---- d a pplied SAR result with Head TSL 3 Condition SAR averaged over 1 cm (1 g) of Head TSL SAR measured 250 mW input power 14.2 W/kg SAR to「 nominalHead TSL parameters no「malizedto 1 W 57.3 W/kg士18.8% (/r-2) 3 Condition SAR averaged over 10 cm (10 g) of Head TSL SAR measured 250 mW input power 6.25 W/kg SAR for nominal Head TSL parameters normalized to 1 W 25.1 W/kg士18.7% (/r-2) Certificate No: Z23-60014 Page 3 of 6 ln Collaborati on with CALIBRATION LABORATORY Add: No.51 Xueyuan Road, Haidian District, Beijing, 100191, Chma Tel: +86-10-62304633-2079 Fax: +86-10-62304633-2504 E-mail: [email protected] http://www.chinattl.cn Appendix(Additional assessments outside the scope of CNAS L0570) Antenna Parameters with Head TSL Impedance, transfo「med to feed point 48.40-6.46j0 Return Loss - 23.4d8 General Antenna Parameters and Design Electrical Delay (one direction) 1.065 ns After long term use with 1 OOW radiated power, only a slight warming of the dipole near the feed point can be measured.
