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.2 = 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 ConvE. e 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. e Axy2; Bxyz: Cxy,2;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. * ConvF and Boundary Effect Parameters: Assessed in flat phantom using E—field (or Temperature Transfer Standard for f800MHz) and inside waveguide using analytical field distributions based on power measurements for f >800MHz. The same setups are used for assessmentof 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 from50MHz toz100MHz. 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: Z17—97167 Page 2 of11
