6.1.5 Device holder description
The DASY device holder has two scales for device rotation (with respect to the body axis) and the device
inclination (with respect to the line between the ear openings). The plane between the ear openings and the
mouth tip has a rotation angle of 65°. The bottom plate contains three pair of bolts for locking the device
holder. The device holder positions are adjusted to the standard measurement positions in the three
sections. This device holder is used for standard mobile phones or PDA’s only. If necessary an additional
support of polystyrene material is used.
Larger DUT’s (e.g. notebooks) cannot be tested using this device holder.
Instead a support of bigger polystyrene cubes and thin polystyrene plates is
used to position the DUT in all relevant positions to find and measure spots with
maximum SAR values.
Therefore those devices are normally only tested at the flat part of the SAM.

6.1.6 Scanning procedure




The DASY installation includes predefined files with recommended procedures for measurements and
system check. 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 highest integrated SAR value is the main concern in compliance test applications. These values
can mostly be found at the inner surface of the phantom and cannot be measured directly due to the
sensor offset in the probe. To extrapolate the surface values, the measurement distances to the
surface must be known accurately. A distance error of 0.5mm could produce SAR errors of 6% at 1800
MHz. Using predefined locations for measurements is not accurate enough. Any shift of the phantom
(e.g., slight deformations after filling it with liquid) would produce high uncertainties. For an automatic
and accurate detection of the phantom surface, the DASY5 system uses the mechanical surface
detection. The detection is always at touch, but the probe will move backward from the surface the
indicated distance before starting the measurement.
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 scan uses different grid spacings for different frequency measurements.
Standard grid spacing for head measurements in frequency ranges ≤ 2GHz is 15 mm in x- and ydimension. For higher frequencies a finer resolution is needed, thus for the grid spacing is reduced
according the following table:
Area scan grid spacing for different frequency ranges
Frequency range
Grid spacing
≤ 2 GHz
≤ 15 mm
2 – 4 GHz
≤ 12 mm
4 – 6 GHz
≤ 10 mm

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. Results of this coarse scan are shown in annex B.
A „zoom scan” measures the field in a volume around the 2D peak SAR value acquired in the previous
„coarse“ scan. It uses a fine meshed grid where the robot moves the probe in steps along all the 3
axis (x, y and z-axis) starting at the bottom of the Phantom. The grid spacing for the cube measurement
is varied according to the measured frequency range, the dimensions are given in the following table:

* When zoom scan is required and the reported SAR from the area scan based 1-g SAR estimation procedures
of KDB Publication 447498 is ≤ 1.4 W/kg, ≤ 8 mm, ≤ 7 mm and ≤ 5 mm zoom scan resolution may be applied,
respectively, for 2 GHz to 3 GHz, 3 GHz to 4 GHz and 4 GHz to 6 GHz.
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
annex B. Test results relevant for the specified standard (see section 3) are shown in table form in
section 7.

6.1.7 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 all points
in the three directions x, y and z. 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 1 to 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 neighbouring volumes are evaluated until no neighbouring 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, Computermathematik, 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
DASY uses the advanced extrapolation option which is able to compensate boundary effects on E-field probes.

6.1.8 Data Storage and Evaluation
Data Storage
The DASY 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 ".DA4", “.DA5x”. 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.
Data Evaluation by SEMCAD
The SEMCAD software automatically executes the following procedures to calculate the field units from the
microvolt readings at the probe connector. The parameters used in the evaluation are stored in the
configuration modules of the software:

These parameters must be set correctly in the software. They can be found in the component documents or
they can be imported into the software from the configuration files issued for the DASY components. In the
direct measuring mode of the multimeter option, the parameters of the 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:

6.1.13 System check
The system check is performed for verifying the accuracy of the complete measurement system and
performance of the software. The system check is performed with tissue equivalent material according to IEEE
1528. The following table shows system check results for all frequency bands and tissue liquids used during
the tests (plot(s) see annex A).

6.1.14 System check procedure
The system check is performed by using a validation 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 1000 mW for frequencies
below 2 GHz or 100 mW for frequencies above 2 GHz. 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 validation 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 (result on plot).
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.

6.1.15 System validation
The system validation is performed in a similar way as a system check. It needs to be performed once a SAR
measurement system has been established and allows an evaluation of the system accuracy with all
components used together with the specified system. It has to be repeated at least once a year or when new
system components are used (DAE, probe, phantom, dipole, liquid type).
In addition to the procedure used during system check a system validation also includes checks of probe
isotropy, probe modulation factor and RF signal.

7.2 SAR test results
7.2.1 General description of test procedures





The DUT is tested with a software provided by the manufacturer to set different test modes for radiated
and conducted testing. Test positions as described in the tables above are in accordance with the
specified test standard.
Tests in body position were performed in that configuration, which generates the highest time based
averaged output power (see conducted power results).
According to IEEE 1528 the SAR test shall be performed at middle channel. Testing of top and bottom
channel is optional.
According to KDB 447498 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
 ≤ 0.6 W/kg or 1.5 W/kg, for 1-g or 10-g respectively, when the transmission band is between 100
MHz and 200 MHz
 ≤ 0.4 W/kg or 1.0 W/kg, for 1-g or 10-g respectively, when the transmission band is ≥ 200 MHz
IEEE 1528-2013 requires the middle channel to be tested first. This generally applies to wireless
devices that are designed to operate in technologies with tight tolerances for maximum output power
variations across channels in the band. 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.
