from the equation SAR= σ (|Ei|2)/ ρ where σ and ρ are the conductivity and mass density of the tissue-Simulate.
The DASY5 system for performing compliance tests consists of the following items:
A standard high precision 6-axis robot (Stabile RX family) with controller, teach pendant and software .An arm
extension for accommodation the data acquisition electronics (DAE).
A dosimetric probe, i.e., an isotropic E-field probe optimized and calibrated for usage in tissue simulating liquid.
The probe is equipped with an optical surface detector system.
A data acquisition electronics (DAE) which performs the signal amplification, signal multiplexing, AD-conversion,
offset measurements, mechanical surface detection, collision detection, etc. The unit is battery powered with
standard or rechargeable batteries. The signal is optically transmitted to the EOC.
The Electro-optical converter (EOC) performs the conversion between optical and electrical of the signals for the
digital communication to DAE and for the analog signal from the optical surface detection. The EOC is connected
to the measurement server.

2.6 Device Holder for Transmitters
F-2. Device Holder for Transmitters

The DASY device holder is designed to cope with different positions given in the standard. It has two scales
for the device rotation (with respect to the body axis) and the device inclination (with respect to the line
between the ear reference points). The rotation centres for both scales are the ear reference point (ERP).
Thus the device needs no repositioning when changing the angles.

The DASY device holder has been made out of low-loss POM material having the following dielectric
parameters: relative permittivity ε=3 and loss tangent δ=0.02. The amount of dielectric material has been
reduced in the closest vicinity of the device, since measurements have suggested that the influence of the
clamp on the test results could thus be lowered.

Measurement procedure
2.7.1 Scanning procedure
Step 1: Power reference measurement
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.
Step 2: Area scan
The SAR distribution at the exposed side of the head was measured at a distance of 4mm from the inner
surface of the shell. The area covered the entire dimension of the head and the horizontal grid spacing was
15mm*15mm or 12mm*12mm or 10mm*10mm.Based on the area scan data, the area of the maximum
absorption was determined by spline interpolation.
Step 3: Zoom scan
Around this point, a volume of 30mm*30mm*30mm (fine resolution volume scan, zoom scan) was assessed by
measuring 5x5x7 points (≤2GHz) and 7x7x7 points (≥2GHz). On this basis of this data set, the spatial peak
SAR value was evaluated with the following procedure:
The data at the surface was extrapolated, since the centre of the dipoles is 2.0mm away from the tip of the
probe and the distance between the surface and the lowest measuring point is 1.2mm. (This can be variable.
Refer to the probe specification).The extrapolation was based on a least square algorithm. A polynomial of the
fourth order was calculated through the points in z-axes. This polynomial was then used to evaluate the points
between the surface and the probe tip. The maximum interpolated value was searched with a straight-forward
algorithm. Around this maximum the SAR values averaged over the spatial volumes (1g or 10g) were computed
using the 3D-Spline interpolation algorithm. The volume was integrated with the trapezoidal algorithm. One
thousand points were interpolated to calculate the average. All neighbouring volumes were evaluated until no
neighboring volume with a higher average value was found.
The area and zoom scan resolutions specified in the table below must be applied to the SAR measurements
Probe boundary effect error compensation is required for measurements with the probe tip closer than half a
probe tip diameter to the phantom surface. Both the probe tip diameter and sensor offset distance must satisfy
measurement protocols; to ensure probe boundary effect errors are minimized and the higher fields closest to
the phantom surface can be correctly measured and extrapolated to the phantom surface for computing 1-g
SAR. Tolerances of the post-processing algorithms must be verified by the test laboratory for the scan
resolutions used in the SAR measurements, according to the reference distribution functions specified in IEEE
Std. 1528-2003.

2.7.2 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 “.DAE”. 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], [m W/g], [m W/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.
2.7.3 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:
Probe parameters: - Sensitivity
- Conversion factor
ConvFi
- Diode compression point
Dcpi
Device parameters: - Frequency
- Crest factor
cf
Media parameters: - Conductivity
- Density
ρ
Normi, ai0, ai1, ai2
ε
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 DCtransmission 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:
With
Vi
= compensated signal of channel i ( i = x, y, z )
Ui = input signal of channel i ( i = x, y, z )
cf = crest factor of exciting field (DASY parameter)
dcp i = diode compression point (DASY parameter)
From the compensated input signals the primary field data for each channel can be evaluated:

SAR System Check
The microwave circuit arrangement for system Check is sketched in F-11. The daily system accuracy
verification occurs within the flat section of the SAM phantom. A SAR measurement was performed to see if the
measured SAR was within +/- 10% from the target SAR values. The tests were conducted on the same days as
the measurement of the EUT. The obtained results from the system accuracy verification are displayed in the
following table (A power level of 250mW (below 3GHz) or 100mW (3-6GHz) was input to the dipole antenna).
During the tests, the ambient temperature of the laboratory was in the range 22±2°C, the relative humidity was
in the range 60% and the liquid depth above the ear reference points was above 15±0.5 cm in all the cases. It is
seen that the system is operating within its specification, as the results are within acceptable tolerance of the
reference values.

4.2.1 Justification for Extended SAR Dipole Calibrations
1) Referring to KDB865664 D01 requirements for dipole calibration, instead of the typical annual calibration
recommended by measurement standards, longer calibration intervals of up to three years may be considered
when it is demonstrated that the SAR target, impedance and return loss of a dipole have remain stable according
to the following requirements. Each measured dipole is expected to evaluate with the following criteria at least on
annual interval in Appendix C.
a) There is no physical damage on the dipole;
b) System check with specific dipole is within 10% of calibrated value;
c) Return-loss is within 10% of calibrated measurement;
d) Impedance is within 5Ω from the previous measurement.
2) Network analyzer probe calibration against air, distilled water and a shorting block performed before measuring
liquid parameters.

5.1.1 Initial Test Position SAR Test Reduction Procedure
DSSS and OFDM configurations are considered separately according to the required SAR procedures. SAR is
measured in the initial test position using the 802.11 transmission mode configuration required by the DSSS
procedure or initial test configuration and subsequent test configuration(s) according to the OFDM procedures.
The initial test position procedure is described in the following:
1). When the reported SAR of the initial test position is ≤ 0.4 W/kg, further SAR measurement is not required for
the other (remaining) test positions in that exposure configuration and 802.11 transmission mode
combinations within the frequency band or aggregated band. SAR is also not required for that exposure
configuration in the subsequent test configuration(s).
2). When the reported SAR of the initial test position is > 0.4 W/kg, SAR is repeated for the 802.11 transmission
mode configuration tested in the initial test position using subsequent highest extrapolated or estimated 1-g
SAR conditions determined by area scans or next closest/smallest test separation distance and maximum RF
coupling test positions based on manufacturer justification, on the highest maximum output power channel,
until the reported SAR is ≤ 0.8 W/kg or all required test positions (left, right, touch, tilt or subsequent surfaces
and edges) are tested.
3). For all positions/configurations tested using the initial test position and subsequent test positions, when the
reported SAR is > 0.8 W/kg, SAR is measured for these test positions/configurations on the subsequent next
highest measured output power channel(s) until the reported SAR is ≤ 1.2 W/kg or all required channels are
tested. a) Additional power measurements may be required for this step, which should be limited to those
necessary for identifying the subsequent highest output power channels.

5.1.1.1 Initial Test Configuration Procedures
An initial test configuration is determined for OFDM transmission modes according to the channel bandwidth,
modulation and data rate combination(s) with the highest maximum output power specified for production units in
each standalone and aggregated frequency band. SAR is measured using the highest measured maximum output
power channel. For configurations with the same specified or measured maximum output power, additional
transmission mode and test channel selection procedures are required. SAR test reduction for subsequent
highest output test channels is determined according to reported SAR of the initial test configuration.
For next to the ear, hotspot mode and UMC mini-tablet exposure configurations where multiple test positions are
required, the initial test position procedure is applied to minimize the number of test positions required for SAR
measurement using the initial test configuration transmission mode. For fixed exposure conditions that do not
have multiple SAR test positions, SAR is measured in the transmission mode determined by the initial test
configuration.
When the reported SAR of the initial test configuration is > 0.8 W/kg, SAR measurement is required for
subsequent next highest measured output power channel(s) in the initial test configuration until reported SAR is ≤
1.2 W/kg or all required channels are tested.
5.1.1.2 Subsequent Test Configuration Procedures
SAR measurement requirements for the remaining 802.11 transmission mode configurations that have not been
tested in the initial test configuration are determined separately for each standalone and aggregated frequency
band, in each exposure condition, according to the maximum output power specified for production units. The
initial test position procedure is applied to next to the ear, UMPC mini-tablet and hotspot mode configurations.
When the same maximum output power is specified for multiple transmission modes, additional power
measurements may be required to determine if SAR measurements are required for subsequent highest output
power channels in a subsequent test configuration. The subsequent test configuration and SAR measurement
procedures are described in the following.
1). When SAR test exclusion provisions of KDB Publication 447498 are applicable and SAR measurement
is not required for the initial test configuration, SAR is also not required for the next highest maximum
output power transmission mode subsequent test configuration(s) in that frequency band or aggregated
band and exposure configuration.
2). When the highest reported SAR for the initial test configuration (when applicable, include subsequent
highest output channels), according to the initial test position or fixed exposure position requirements, is
adjusted by the ratio of the subsequent test configuration to initial test configuration specified maximum
output power and the adjusted SAR is ≤ 1.2 W/kg, SAR is not required for that subsequent test
configuration.
3). The number of channels in the initial test configuration and subsequent test configuration can be
different due to differences in channel bandwidth. When SAR measurement is required for a subsequent
test configuration and the channel bandwidth is smaller than that in the initial test configuration, all
channels in the subsequent test configuration that overlap with the larger bandwidth channel tested in
the initial test configuration should be used to determine the highest maximum output power channel.
This step requires additional power measurement to identify the highest maximum output power channel
in the subsequent test configuration to determine SAR test reduction.
a)SAR should first be measured for the channel with highest measured output power in the
subsequent test configuration.
b) SAR for subsequent highest measured maximum output power channels in the subsequent test
configuration is required only when the reported SAR of the preceding higher maximum output
power channel(s) in the subsequent test configuration is > 1.2 W/kg or until all required
channels are tested. i) For channels with the same measured maximum output power, SAR
should be measured using the channel closest to the center frequency of the larger channel
bandwidth channel in the initial test configuration.
4). SAR measurements for the remaining highest specified maximum output power OFDM transmission
mode configurations that have not been tested in the initial test configuration (highest maximum output)
or subsequent test configuration(s) (subsequent next highest maximum output power) is determined by
recursively applying the subsequent test configuration procedures in this section to the remaining
configurations according to the following:
a)replace “subsequent test configuration” with “next subsequent test configuration” (i.e., subsequent
next highest specified maximum output power configuration)
b) replace “initial test configuration” with “all tested higher output power configurations”

5.1.1.3 2.4 GHz SAR Procedures
Separate SAR procedures are applied to DSSS and OFDM configurations in the 2.4 GHz band to simplify DSSS
test requirements. For 802.11b DSSS SAR measurements, DSSS SAR procedure applies to fixed exposure test
position and initial test position procedure applies to multiple exposure test positions. When SAR measurement is
required for an OFDM configuration, the initial test configuration, subsequent test configuration and initial test
position procedures are applied. The SAR test exclusion requirements for 802.11g/n OFDM configurations are
described in following.

802.11b DSSS SAR Test Requirements
SAR is measured for 2.4 GHz 802.11b DSSS using either a fixed test position or, when applicable, the initial test
position procedure. SAR test reduction is determined according to the following:
1). When the reported SAR of the highest measured maximum output power channel for the exposure
configuration is ≤ 0.8 W/kg, no further SAR testing is required for 802.11b DSSS in that exposure
configuration.
2). When the reported SAR is > 0.8 W/kg, SAR is required for that exposure configuration using the next
highest measured output power channel. When any reported SAR is > 1.2 W/kg, SAR is required for the
third channel; i.e., all channels require testing.

2.4 GHz 802.11g/n OFDM SAR Test Exclusion Requirements
When SAR measurement is required for 2.4 GHz 802.11g/n OFDM configurations, the measurement and test
reduction procedures for OFDM are applied (section 5.3, including sub-sections). SAR is not required for the
following 2.4 GHz OFDM conditions.
1). When KDB Publication 447498 SAR test exclusion applies to the OFDM configuration.
2). When the highest reported SAR for DSSS is adjusted by the ratio of OFDM to DSSS specified maximum
output power and the adjusted SAR is ≤ 1.2 W/kg.

Note: Per KDB248227D01, for Body SAR test of WiFi 2.4G,
1) SAR is measured for 2.4 GHz 802.11b DSSS using the initial test position procedure.
2) As the highest reported SAR for DSSS is adjusted by the ratio of OFDM 802.11g/n to DSSS specified
maximum output power and the adjusted SAR is < 1.2 W/kg, so SAR for 802.11g/n is not required.

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
b) IEC 62209-1,"Measurement procedure for the assessment of Specific Absorption Rate (SAR) from
hand一 held and body-mounted devices used next to the ear (frequency range of 300 MHz to 6 GHz)",
July 2016
c) IEC 62209一 2, "Procedure to determine the Specific Absorption Rate (SAR) for wireless communication
devices used in close proximity to the human body (frequency range of 30 MHz to 6 GHz)", March
2010
d) KDB 865664, "SAR Measurement Requirements for 100 MHz to 6 GHz"
Methods Applied and Interpretation of Parameters:
. NORMx,y,z: Assessed for E-field polarization e=o (f900MHz in TEM一 cell; f>1800MHz: waveguide).
NORMx,y,z are only intermediate values, i.e.,the uncertainties of NORMx,y,z does not effect the
E2 -field uncertainty inside 丁SL (see below ConvF).
・ NORM仍x,y, z 二 NORMx,y, f' 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.
PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal
characteristics.
. Ax,y,z; 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'800MHz) and inside waveguide using analytical field distributions based on
power measurements for f >800MHz. The same setups are used for assessment of the parameters
applied for boundary compensation (alpha,depth) of which typical uncertainty valued are given.
These parameters are used in DASY4 software to improve probe accuracy close to

to
that given for ConvF. A frequency dependent ConvF is used in DASY version 4.4 and higher which
allows extending the validity from士 50MHz to士 100MHz.
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%.
丁he uncertainties of Norm X, 丫 Z do not affect the E2-field uncertainty inside TSL (see Page 5 and Page 6).
Numerical linearization parameter: uncertainty not required.
Uncertainly is determined using the max. deviation from linear response applying rectangular distribution
and is expressed for the square of the field value.
