NORMDxy.z = NORMxy.2 * frequency_response (see Frequency Response Chart). This Iinearization is implemented in DASY4 software versions later than 4.2. The uncertainty ofthe frequency responseis included in the stated uncertainty of ConvF. DCPx,y,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW signal (no uncertainty required). DGP does not dapend on frequency nor media: PAR: PAR is the Peak to Average Ratiothat is not calibrated but determined based on the signal characteristics Axyie: Bxy.z: Cioy.z: Dxyiz: VRey.z: A, 8. C, D are numerical Inearization 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 calbration range expressed in RMS vollage across the diode. ConvF and Boundary Effact Parameters: Assessed in lat phantom using E—feld (or Temperature Transfer Standard for f < 800 Mz) and inside waveguide using analyticalfeld distrbutions based on power measurements for { > 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 NORMxy.z * Convwhereby the uncertainty corresponds to that given for Conv. A frequency dependent ConvFis 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 tothe offset of vitual 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 NORMs (no uncertainty required). Certficate No: EX3—3057_ May18 Page 2 o11
