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(Mx,y,z = 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,yz; Cx,yz;VRx,y,z:A,B,C are numericallinearization 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 analyticalfield 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 sensoroffset 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 NORMsx (no uncertainty required). Certificate No: Z18—60160 Page 2 of 11

The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm of the dipole. The antennais therefore short—circuited for DC—signals. On some ofthe 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.
