NORMx,y,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not effect the E" field uncertainty inside TSL (see below ConvF). e NORM(Px,y,z2 = NORMx,y,z* frequency_response (see Frequency Response Chart). This linearization is implemented in DASY4 software versions later than 4.2. The uncertainty of the frequency response is included in the stated uncertainty of ConvF. e DCPx,y,z; DCP are numerical linearization parameters assessed based on the data of power sweep (no uncertainty required). DCP does not depend on frequency nor media. e PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal characteristics. e Axyz Bx,y,z; Cx,y,z;VRx,y,z:A,B,C are numerical linearization parameters assessed based on the data of power sweep for specific modulation signal. The parameters do not depend on frequency nor media. VR is the maximum calibration range expressed in RMS voltage across the diode. e ConvF and Boundary Effect Parameters: Assessed in flat phantom using E—field (or Temperature Transfer Standard for fs800MHz) and inside waveguide using analytical field distributions based on power measurements for f >800MHz. The same setups are used for assessment of the parameters applied for boundary compensation (alpha, depth) of which typical uncertainty valued are given. These parameters are used in DASY4 software to improve probe accuracy close to the boundary. The sensitivity in TSL corresponds to NORMx,y,z* ConvF whereby the uncertainty corresponds to that given for ConvF. A frequency dependent ConvF is used in DASY version 4.4 and higher which allows extending the validity from:+50MHz to+100MHz. e Spherical isotropy (3D deviation from isotropy): in a field of low gradients realized using a flat phantom exposed by a patch antenna. e Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required. e Connector Angle: The angle is assessed using the information gained by determining the NORMx (no uncertainty required). Certificate No: Z19—60101 Page 2 of 11

The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connectedto the secondarmof the dipole. The antenna is therefore short—circuitedfor DC—signals. On some of the dipoles, small end caps are addedto the dipole arms in order to improve matching when loaded according to the position as explainedin the "Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still according to the Standard. No excessive force must be applied to the dipole arms, because they might bendor the soldered connections near the feedpoint may be damaged.

All figures stated in the certificate are valid at the frequency indicated. e Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed point exactly below the center marking of the fiat phantom section, with the arms oriented paralle! to the body axis. e Feed Point Impedance and Return Loss: These parameters are measured with the dipole positioned under the liquid filled phantom. 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. e 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 W at the antenna connector. e 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%.

The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm ofthe dipole. The antenna is therefore short—clreuited for DC—signals. On some of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded according to the position as explained in the "Measurement Conditions" paragraph, The SAR data are not affected by this change. The overall dipole length is still according to the Standard. No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the feedpoint may be damaged.
