Calibration is Performed According to the Following Standards:
     a)   IEEE Std 1528—2003, "IEEE Recommended Practice for Determining the Peak Spatial—Averaged Specific
          Absorption Rate (SAR) in the Human Head from Wireless Communications Devices: Measurement
          Techniques", December 2003
     b)   IEC 62209—1, "Procedure to measure the Specific Absorption Rate (SAR) for hand—held devices used in close
          proximity to the ear (frequency range of 300 MHz to 3 GHz)", February 2005

Methods Applied and Interpretation of Parameters:
          NORMx,y,z: Assessed for E—field polarization 9 = 0 (f < 900 MHz in TEM—cell; f> 1800 MHz: R22 waveguide}.
          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 betow ConvF).
          NORM(Px,y, z = NORMx,y, 2 * 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.
          DCPx,y,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,
          Ax.y,2; Bx.y,z; Cx,y,z, 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 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.

 The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied
 by the coverage factor k=2, which for a normal distribution corresponds to a coverage probability of
 approximately 95%.


* The uncertainties of NormX,Y,Z do not affect the E—field uncertainty inside TSL (see Pages 5 and 6).
® Numerical linearization parameter: uncertainty not required.
© Uncertainty is determined using the maximum deviation from linear response applying recatangular distribution and is expressed for the square of the field value.
