NORMx,y,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not affect the E*—field uncertainty inside TSL (see below ConvF). * NORM(Mx,y,2 = NORMxy,z * frequency_response (see Frequency Response Chart). This linearization is implemented in DASY4 software versions later than 4.2. The uncertainty of the frequency responseis included in the stated uncertainty of ConvF. * DCPxy,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW signal (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 + Amyai Boyia Coye Day.z: VRxy.z: A, B, C, D 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 f = 800 MHz) and inside waveguide using analytical field distributions based on power measurements for f > 800 MHz. The same setups are used for assessment of the parameters applied for boundary compensation (alpha, depth) of which typical uncertainty values 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 + 50 MHz to + 100 MHz. «_ 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 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: EX3—3536_Jul1d4 Page 2 of 11
