                                                     NORMx,y,z are only intermediate values, L.e., the uncertainties of NORMx,y,z does not affect the E*—field
                                                     uncertainty inside TSL (see below ConvF).
                                                     NORM(Mx,y,z = 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 response is included
                                                     in the stated uncertainty of ConvF.
                                                     DCPxy,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW

                                                     to NORMx,y,z * Conv whereby the uncertainty corresponds to that given for ConvF. A frequency dependent

                                                     (on probe axis). No tolerance required.
