4.2.2. E-FIELD PROBE CALIBRATION
Each probe is calibrated according to a dosimetric assessment procedure with accuracy better
than ±10%. The spherical isotropy was evaluated and found to be better than ± 0.25dB. The
sensitivity parameters (NormX, NormY, NormZ), the diode compression parameter (DCP) and
the conversion factor (ConvF) of the probe are tested.
The free space E-field from amplified probe outputs is determined in a test chamber. This is
performed in a TEM cell for frequencies bellow 1 GHz, and in a wave guide above 1 GHz for
free space. For the free space calibration, the probe is placed in the volumetric center of the
cavity and at the proper orientation with the field. The probe is then rotated 360 degrees.
E-field temperature correlation calibration is performed in a flat phantom filled with the
appropriate simulated brain tissue. The measured free space E-field in the medium correlates
to temperature rise in a dielectric medium. For temperature correlation calibration a RF
transparent thermistor-based temperature probe is used in conjunction with the E-field probe.

4.2.4. SCANNING PROCEDURE
The DASY5 installation includes predefined files with recommended procedures for
measurements and validation. They are read-only document files and destined as fully defined
but unmeasured masks. All test positions (head or body-worn) are tested with the same
configuration of test steps differing only in the grid definition for the different test positions.
The “reference” and “drift” measurements are located at the beginning and end of the batch
process. They measure the field drift at one single point in the liquid over the complete procedure.
The indicated drift is mainly the variation of the DUT’s output power and should vary max. ± 5 %.
The “surface check” measurement tests the optical surface detection system of the DASY5
system by repeatedly detecting the surface with the optical and mechanical surface detector and
comparing the results. The output gives the detecting heights of both systems, the difference
between the two systems and the standard deviation of the detection repeatability. Air bubbles or
refraction in the liquid due to separation of the sugar-water mixture gives poor repeatability (above
± 0.1mm). To prevent wrong results tests are only executed when the liquid is free of air bubbles.
The difference between the optical surface detection and the actual surface depends on the probe
and is specified with each probe. (It does not depend on the surface reflectivity or the probe angle
to the surface within ± 30°.)

Area Scan
The “area scan” measures the SAR above the DUT or verification dipole on a parallel plane to the
surface. It is used to locate the approximate location of the peak SAR with 2D spline interpolation.
The robot performs a stepped movement along one grid axis while the local electrical field strength
is measured by the probe. The probe is touching the surface of the SAM during acquisition of
measurement values. The standard scan uses large grid spacing for faster measurement.
Standard grid spacing for head measurements is 15 mm in x- and y- dimension(≤2GHz),12 mm
in x- and y- dimension(2-4 GHz) and 10mm in x- and y- dimension(4-6GHz). If a finer resolution is
needed, the grid spacing can be reduced. Grid spacing and orientation have no influence on the
SAR result. For special applications where the standard scan method does not find the peak SAR
within the grid, e.g. mobile phones with flip cover, the grid can be adapted in orientation.

Zoom Scan
A “zoom scan” measures the field in a volume around the 2D peak SAR value acquired in the
previous “coarse” scan. This is a fine grid with maximum scan spatial resolution: Δxzoom, ∆yzoom≤
2GHz -≤8mm, 2-4GHz -≤5 mm and 4-6 GHz-≤4mm; ∆zzoom≤3GHz -≤5 mm, 3-4 GHz-≤4mm
and 4-6GHz-≤2mm where the robot additionally moves the probe along the z-axis away from the
bottom of the Phantom. DASY is also able to perform repeated zoom scans if more than 1 peak is
found during area scan. In this document, the evaluated peak 1g and 10g averaged SAR values
are shown in the 2D-graphics in Appendix B. Test results relevant for the specified standard (see
chapter 1.4.)are shown in table form form in chapter 7.2.
A Z-axis scan measures the total SAR value at the x-and y-position of the maximum SAR value
found during the cube scan. The probe is moved away in z-direction from the bottom of the SAM
phantom in 2 mm steps. This measurement shows the continuity of the liquid and can - depending
in the field strength – also show the liquid depth.

The following table summarizes the area scan and zoom scan resolutions per FCC KDB
865664D01:
4.2.5. SPATIAL PEAK SAR EVALUATION
The spatial peak SAR - value for 1 and 10 g is evaluated after the Cube measurements have been
done. The basis of the evaluation are the SAR values measured at the points of the fine cube grid
consisting of 5 x 5 x 7 points( with 8mm horizontal resolution) or 7 x 7 x 7 points( with 5mm
horizontal resolution) or 8 x 8 x 7 points( with 4mm horizontal resolution). The algorithm that finds
the maximal averaged volume is separated into three different stages.

The data between the dipole center of the probe and the surface of the phantom are
extrapolated. This data cannot be measured since the center of the dipole is 2.7 mm away
from the tip of the probe and the distance between the surface and the lowest measuring point
is about 1 mm (see probe calibration sheet). The extrapolated data from a cube
measurement can be visualized by selecting “Graph Evaluated”.

The maximum interpolated value is searched with a straight-forward algorithm. Around this
maximum the SAR - values averaged over the spatial volumes (1g or 10 g) are computed
using the 3d-spline interpolation algorithm. If the volume cannot be evaluated (i.e., if a part of
the grid was cut off by the boundary of the measurement area) the evaluation will be started
on the corners of the bottom plane of the cube.

All neighboring volumes are evaluated until no neighboring volume with a higher average
value is found.
Extrapolation
The extrapolation is based on a least square algorithm [W. Gander,
Computermathematik,p.168-180]. Through the points in the first 3 cm along the z-axis,
polynomials of order four are calculated. These polynomials are then used to evaluate the points
between the surface and the probe tip. The points, calculated from the surface, have a distance
of 1 mm from each other.
Interpolation
The interpolation of the points is done with a 3d-Spline. The 3d-Spline is composed of three
one-dimensional splines with the "Not a knot"-condition [W. Gander, Computer mathematik,
p.141-150] (x, y and z -direction) [Numerical Recipes in C, Second Edition, p.123ff ].
Volume Averaging
At First the size of the cube is calculated. Then the volume is integrated with the trapezoidal
algorithm. 8000 points (20x20x20) are interpolated to calculate the average.
Advanced Extrapolation
DASY5 uses the advanced extrapolation option which is able to compansate boundary effects on
E-field probes.

4.2.6. DATA STORAGE AND EVALUATION
4.2.6.1 Data Storage
The DASY5 software stores the acquired data from the data acquisition electronics as raw data (in
microvolt readings from the probe sensors), together with all necessary software parameters for
the data evaluation (probe calibration data, liquid parameters and device frequency and
modulation data) in measurement files with the extension “.DAE4”. The software evaluates the
desired unit and format for output each time the data is visualized or exported. This allows
verification of the complete software setup even after the measurement and allows correction of
incorrect parameter settings. For example, if a measurement has been performed with a wrong
crest factor parameter in the device setup, the parameter can be corrected afterwards and the
data can be re-evaluated.
The measured data can be visualized or exported in different units or formats, depending on the
selected probe type ([V/m], [A/m], [°C], [mW/g], [mW/cm²], [dBrel], etc.). Some of these units are
not available in certain situations or show meaningless results, e.g., a SAR output in a lossless
media will always be zero. Raw data can also be exported to perform the evaluation with other
software packages.

actual system setup are used. In the scan visualization and export modes, the parameters stored in
the corresponding document files are used.
The first step of the evaluation is a linearization of the filtered input signal to account for the
compression characteristics of the detector diode. The compensation depends on the input signal,
the diode type and the DC-transmission factor from the diode to the evaluation electronics.
If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate
for peak power. The formula for each channel can be given as:
Vi = Ui + Ui2 · cf / dcpi
With
Vi = compensated signal of channel i
Ui = input signal of channel i
cf = crest factor of exciting field
dcpi = diode compression point

Note that the density is normally set to 1 (or 1.06), to account for actual brain density rather than the
density of the simulation liquid. The power flow density is calculated assuming the excitation field to
be a free space field.
Ppwe = Etot2 / 3770 or Ppwe = Htot2 · 37.7
With
Ppwe = equivalent power density of a plane wave in mW/cm2
Etot = total field strength in V/m

Note:
1) The dielectric parameters of the tissue-equivalent liquid should be measured under similar
ambient conditions and within 2 °C of the conditions expected during the SAR evaluation to satisfy
protocol requirements.
2) KDB 865664 was ensured to be applied for probe calibration frequencies greater than or equal
to 50MHz of the EUT frequencies.
3) The above measured tissue parameters were used in the DASY software to perform interpolation via
the DASY software to determine actual dielectric parameters at the test frequencies. The SAR test
plots may slightly differ from the table above since the DASY rounds to three significant digits.

5.3. SYSTEM CHECK PROCEDURE
The system check is performed by using a system check dipole which is positioned parallel to the
planar part of the SAM phantom at the reference point. The distance of the dipole to the SAM phantom
is determined by a plexiglass spacer. The dipole is connected to the signal source consisting of signal
generator and amplifier via a directional coupler, N-connector cable and adaption to SMA. It is fed with
a power of 250 mW(below 5GHz) or 100mW(above 5GHz). To adjust this power a power meter is used.
The power sensor is connected to the cable before the system check to measure the power at this point
and do adjustments at the signal generator. At the outputs of the directional coupler both return loss as
well as forward power are controlled during the system check to make sure that emitted power at the
dipole is kept constant. This can also be checked by the power drift measurement after the test.
System check results have to be equal or near the values determined during dipole calibration (target
SAR in table above) with the relevant liquids and test system (±10 %).

6.. SAR MEASUREMENT VARIABILITY AND UNCERTAINTY
6.1. SAR MEASUREMENT VARIABILITY
Per KDB865664 D01 SAR measurement 100 MHz to 6 GHz, SAR measurement variability must be
assessed for each frequency band, which is determined by the SAR probe calibration point and
tissue-equivalent medium used for the device measurements. The additional measurements are
repeated after the completion of all measurements requiring the same head or body tissue-equivalent
medium in a frequency band. The test device should be returned to ambient conditions (normal room
temperature) with the battery fully charged before it is re-mounted on the device holder for the
repeated measurement(s) to minimize any unexpected variations in the repeated results.
1) Repeated measurement is not required when the original highest measured SAR is < 0.80 W/kg;
steps 2) through 4) do not apply.
2) When the original highest measured SAR is ≥ 0.80 W/kg, repeat that measurement once.
3) Perform a second repeated measurement only if the ratio of largest to smallest SAR for the original
and first repeated measurements is > 1.20 or when the original or repeated measurement is≥ 1.45
W/kg (~ 10% from the 1-g SAR limit).
4) Perform a third repeated measurement only if the original, first or second repeated measurement is
≥1.5 W/kg and the ratio of largest to smallest SAR for the original, first and second repeated
measurements is > 1.20.
The same procedures should be adapted for measurements according to extremity and occupational
exposure limits by applying a factor of 2.5 for extremity exposure and a factor of 5 for occupational
exposure to the corresponding SAR thresholds.
The detailed repeated measurement results are shown in Section 8.2.

8.2. SAR TEST RESULTS
General Notes:
1) Per KDB447498 D01, all measurement SAR results are scaled to the maximum tune-up
tolerance limit to demonstrate compliant.
2) Per KDB447498 D01, testing of other required channels within the operating mode of a
frequency band is not required when the reported 1-g or 10-g SAR for the mid-band or highest
output power channel is:≤0.8 W/kg or 2.0 W/kg, for 1-g or 10-g respectively, when the
transmission band is≤100 MHz. When the maximum output power variation across the
required test channels is > ½ dB, instead of the middle channel, the highest output power
channel must be used.
3) Per KDB865664 D01,for each frequency band, repeated SAR measurement is required only
when the measured SAR is ≥0.8W/kg; if the deviation among the repeated measurement is ≤
20%,and the measured SAR <1.45W/kg, only one repeated measurement is required.
4) Per KDB865664 D02, SAR plot is only required for the highest measured SAR in each
exposure configuration, wireless mode and frequency band combination; Plots are also
required when the measured SAR is > 1.5 W/kg, or > 7.0 W/kg for occupational exposure. The
published RF exposure KDB procedures may require additional plots; for example, to support
SAR to peak location separation ratio test exclusion and/or volume scan post-processing.
