NORMxy,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not effect the E" feld uncertainty inside TSL (see below ConvF). * NORM(xy2 = NORMx.y,2" 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. * DCPx,y,2: DCP are numerical linearization parameters assessed based on the data of power sweep (no uncertainty required). DCP does not depend on frequency nor media. «_ PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal characteristics. * Axyz; Buy.z: Coyz;VRxy,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. * 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 >B0OMHz. 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* Conywhereby 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. * Spherical isotropy (3D deviation from isotropy): in a field of low gradients realized using a fiat phantom exposed by a patch antenna. * Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required. * Connector Angle: The angle is assessed using the information gained by determining the NORMx (no uncertainty required). Certificate No: Z17—97052 Page 2 of 11

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. 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. PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on thesignal characteristics. Axy.z; Bx.y.z; Cxy,2z; VRXy.2: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. ConvF and Boundary Effect Parameters: Assessed in flat phantom using E—field (or Temperature Transfer Standard for f5800MHz) 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* Conv whereby the uncertainty corresponds to that given for ConvF. A frequency dependent Convr is used in DASY version 4.4 and higher which allows extending thevalidity from::50MHz tos100MHz. Spherical isotropy (3D deviation from isotropy); in a field of low gradients realized using a flat phantom exposed by a patch antenna. Sensor Offset: The sensor offset corresponds to theoffset of virtual measurement center from the probe tip (on probe axis). No tolerance required. Connector Angle: The angle is assessed using the information gained by determining the NORMx (no uncertainty required) Certi ficate No: Z17—97152 Page 2 of11
