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. * DCPxy,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. * Asyz Buyz; Coyz;VRuyzA,B,C are numerical linearization parameters assessed based on the data of power sweepfor 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 fsBOOMFHz) and inside waveguide using analylical 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" Convwhereby 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 froma50MHz tox10OMHz. * 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 sensoroffset corresponds to the offset of virtual measurement centerfrom 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: Z18—60364 Page 2 of 11
