Polarization 4               o rotation around probe axis
Polarization 8               8 rotation around an axis that is in the plane normal to probe axis (at
                             measurement center), i.e., 8 = 0 is normal to probe axis

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) CENELEC EN 50361, "Basic standard for the measurement of Specific Absorption Rate
       related to human exposure to electromagnetic fields from mobile phones (300 MHz — 3
      GHz), July 2001

Methods Applied and Interpretation of Parameters:
     NORMx,y,z: Assessed for E—field polarization 8 = 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 below ConvF).
         NORM(P)x,y,z = NORMx,y,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.
         DCPx,y,z: DCP are numerical linearization parameters assessed based on the data of
         power sweep (no uncertainty required). DCP does not depend on frequency nor media.
         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 muiltiplied 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 Page 8).
    Numerical linearization parameter: uncertainty not required.
