Calibration is Performed According to the Following Standards:
a) IEEE Std 1528—2013, "IEEE Recommended Practice for Determining the Peak
  Spatial—Averaged Specific Absorption Rate (SAR) in the Human Head from Wireless
    Communications Devices: Measurement Techniques", June 2013

   exposure to radio frequency fields from hand—held and body—mounted wireless
   communication devices— Part 1: Device used next to the ear (Frequency range of 300MHz to
   6GHz)", July 2016
c) IEC 62209—2, "Procedure to measure the Specific Absorption Rate (SAR) For wireless
   communication devices used in close proximity to the human body (frequency range of
   30MHz to 6GHz)", March 2010
d) KDB865664, SAR Measurement Requirements for 100 MHz to 6 GHz

Additional Documentation:
e) DASY4/5 System Handbook

Methods Applied and Interpretation of Parameters:
e    Measurement Conditions: Further details are available from the Validation Report at the end
     of the certificate. All figures stated in the certificate are valid at the frequency indicated.
e    Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed
     point exactly below the center marking of the flat phantom section, with the arms oriented
     paraliel to the body axis.
e    Feed Point Impedance and Return Loss: These parameters are measured with the dipole
     positioned under the liquid filled phantom. The impedance stated is transformed from the
     measurement at the SMA connector to the feed point. The Return Loss ensures low
     reflected power. No uncertainty required.
e    Electrical Delay: One—way delay between the SMA connector and the antenna feed point.
     No uncertainty required.
     SAR measured: SAR measured at the stated antenna input power.
     SAR normalized: SAR as measured, normalized to an input power of 1 W at the antenna
     connector.
e    SAR for nominal TSL parameters: The measured TSL parameters are used to calculate the
     nominal SAR result.


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

 General Antenna Parameters and Design

 After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can
 be measured.


 The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly
 connected to the second arm of the dipole. The antenna is therefore short—circuited for DC—signals. On some
 of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded
 according to the position as explained in the "Measurement Conditions" paragraph. The SAR data are not
 affected by this change. The overall dipole length is still according to the Standard.
 No excessive force must be applied to the dipole arms, because they might bend or the soldered
 connections near the feedpoint may be damaged.
