3 Specific Absorption Rate (SAR)
Page 10 of 69
Introduction
SAR is related to the rate at which energy is absorbed per unit mass in an object exposed to a radio field. The SAR distribution in a biological body is complicated and is usually carried out by experimental techniques or numerical modeling. The standard recommends limits for two tiers of groups, occupational/controlled and general population/uncontrolled, based on a person's awareness and ability to exercise control over his or her exposure. In general, occupational/controlled exposure limits are higher than the limits for general population/uncontrolled.
SAR Definition
The SAR definition is the time derivative (rate) of the incremental energy (dW) absorbed by (dissipated in) an incremental mass (dm) contained in a volume element (dv) of a given density ().The equation description is as below:
= () = ()
SAR is expressed in units of Watts per kilogram (W/kg) SAR measurement can be either related to the temperature elevation in tissue by
= ( )
Where: C is the specific head capacity, T is the temperature rise and tisthe exposure duration, or related to the electrical field in the tissue by
|| =
Where: is the conductivity of the tissue, is the mass density of the tissue and E is the RMS electrical field strength. However for evaluating SAR of low power transmitter, electrical field measurement is typically applied.

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. A white cover is provided to
tap the phantom during off-periods to prevent water evaporation and changes in the liquid parameters.
On the phantom top, three reference markers are provided to identify the phantom position with respect
to the robot.

Photo of ELI4 Phantom
The ELI4 phantom is intended for compliance testing of handheld and body-mounted wireless devices in the frequency range of 30 MHz to 6 GHz. ELI4 is fully compatible with standard and all known tissue simulating liquids.
Device Holder
The SAR in the phantom is approximately inversely proportional to the square of the distance between the source and the liquid surface. For a source at 5 mm distance, a positioning uncertainty of ±0.5mm would produce a SAR uncertainty of ± 20%. Accurate device positioning is therefore crucial for accurate and repeatable measurements. The positions in which the devices must be measured are defined by the standards. 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 center for both scales is the ear reference point (ERP).Thus the device needs no repositioning when changing the angles.
Report No.: CTA24040900105
Page 15 of 69
The DASY device holder is constructed of low-loss POM material having the following dielectric
parameters: relative permittivity = 3 and loss tangent = 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.
Device Holder
Data Storage and Evaluation
Data Storage
The DASY software stores the assessed data from the data acquisition electronics as raw data (in
microvolt readings from the probe sensors), together with all the necessary software parameters for the
data evaluation (probe calibration data, liquid parameters and device frequency and modulation data) in
measurement files. The post-processing 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 erroneous parameter settings. For example, if a measurement
has been performed with an incorrect crest factor parameter in the device setup, the parameter can be
corrected afterwards and the data can be reevaluated.
The measured data can be visualized or exported in different units or formats, depending on the selected
probe type (e.g., [V/m], [A/m], [W/kg]). Some of these units are not available in certain situations or give
meaningless results, e.g., a SAR-output in a non-lose media, will always be zero. Raw data can also be
exported to perform the evaluation with other software packages.
Data Evaluation
The DASY post-processing software (SEMCAD) 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
Normi, ai0, ai1, ai2
- Conversion factor
ConvFi
- Diode compression point dcpi
Device parameters - Frequency
f
- Crest factor
cf
Media parameters - Conductivity
- Density
Report No.: CTA24040900105
Page 16 of 69
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 multi-meter 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
=
+
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) dcpi = diode compression point (DASY parameter)
From the compensated input signals, the primary field data for each channel can be evaluated

The RSS value of the field components gives the total field strength (Hermitian magnitude)

The primary field data are used to calculate the derived field units.

Note:
1. The calibration certificate of DASY can be referred to appendix C of this report.
2. The dipole calibration interval can be extended to 3 years with justification. The dipoles are also not physically
damaged, or repaired during the interval.
3. The Insertion Loss calibration of Dual Directional Coupler and Attenuator were characterized via the network analyzer
and compensated during system check.
4. The dielectric probe kit was calibrated via the network analyzer, with the specified procedure (calibrated in pure water)
and calibration kit (standard) short circuit, before the dielectric measurement. The specific procedure and calibration
kit are provided by Agilent.
5. In system check we need to monitor the level on the power meter, and adjust the power amplifier level to have precise
power level to the dipole; the measured SAR will be normalized to 1W input power according to the ratio of 1W to
the input power to the dipole. For system check, the calibration of the power amplifier is deemed not critically required
for correct measurement; the power meter is critical and we do have calibration for it

7 System Verification Procedures
Page 20 of 69
Each DASY system is equipped with one or more system validation kits. These units, together with the predefined measurement procedures within the DASY software, enable the user to conduct the system performance check and system validation. System validation kit includes a dipole, tripod holder to fix it underneath the flat phantom and a corresponding distance holder.
Purpose of System Performance check
The system performance check verifies that the system operates within its specifications. System and operator errors can be detected and corrected. It is recommended that the system performance check be performed prior to any usage of the system in order to guarantee reproducible results. The system performance check uses normal SAR measurements in a simplified setup with a well characterized source. This setup was selected to give a high sensitivity to all parameters that might fail or vary over time. The system check does not intend to replace the calibration of the components, but indicates situations where the system uncertainty is exceeded due to drift or failure.
System Setup
In the simplified setup for system evaluation, the EUT is replaced by a calibrated dipole and the power source is replaced by a continuous wave that comes from a signal generator. The calibrated dipole must be placed beneath the flat phantom section of the SAM twin phantom with the correct distance holder. The distance holder should touch the phantom surface with a light pressure at the reference marking and be oriented parallel to the long side of the phantom. The equipment setup is shown below:

Body-Supported Device Configurations
According to KDB 616217 section 4.3, SAR should be separately assessed with each surface and separation distance positioned against the flat phantom that correspond to the intended use as specified by the manufacturer. The antennas in tablets are typically located near the back (bottom) surface and/or along the edges of the devices; therefore, SAR evaluation is required for these configurations. Exposures from antennas through the front (top) surface of the display section of a full-size tablet, away from the edges, are generally limited to the user's hands. Exposures to hands for typical consumer transmitters used in tablets are not expected to exceed the extremity SAR limit; therefore, SAR evaluation for the front surface of tablet display screens are generally not necessary, except for tablets that are designed to require continuous operations with the hand(s) next to the antenna(s).
To position the device parallel to the phantom surface with either keypad up or down.
To adjust the device parallel to the flat phantom.
To adjust the distance between the device surface and the flat phantom to 0 mm.
When each surface is measurement, the SAR Test Exclusion Threshold in KDB 447498 should be applied.

9 Measurement Procedures
Page 23 of 69
The measurement procedures are as follows: (a) Use base station simulator (if applicable) or engineering software to transmit RF power continuously (continuous Tx) in the middle channel. (b) Keep EUT to radiate maximum output power or 100% duty factor (if applicable) (c) Measure output power through RF cable and power meter. (d) Place the EUT in the positions as setup photos demonstrates. (e) Set scan area, grid size and other setting on the DASY software. (f) Measure SAR transmitting at the middle channel for all applicable exposure positions. (g) Identify the exposure position and device configuration resulting the highest SAR (h) Measure SAR at the lowest and highest channels attheworst exposure position and device configuration if applicable.
According to the test standard, the recommended procedure for assessing the peak spatial-average SAR value consists of the following steps: (a) Power reference measurement (b) Area scan (c) Zoom scan (d) Power drift measurement
Spatial Peak SAR Evaluation
The procedure for spatial peak SAR evaluation has been implemented according to the test standard. It can be conducted for 1g and 10g, as well as for user-specific masses. The DASY software includes all numerical procedures necessary to evaluate the spatial peak SAR value. The base for the evaluation is a "cube" measurement. The measured volume must include the 1g and 10g cubes with the highest averaged SAR values. For that purpose, the center of the measured volume is aligned to the interpolated peak SAR value of a previously performed area scan. The entire evaluation of the spatial peak values is performed within the post-processing engine (SEMCAD). The system always gives the maximum values for the 1g and 10g cubes. The algorithm to find the cube with highest averaged SAR is divided into the following stages:
(a) Extraction of the measured data (grid and values) from the Zoom Scan (b) Calculation of the SAR value at every measurement point based on all stored data (A/D values
and measurement parameters) (c) Generation of a high-resolution mesh within the measured volume (d) Interpolation of all measured values form the measurement grid to the high-resolution grid (e) Extrapolation of the entire 3-D field distribution to the phantom surface over the distance from
sensor to surface (f) Calculation of the averaged SAR within masses of 1g and 10g
Power Reference Measurement
The Power Reference Measurement and Power Drift Measurements are for monitoring the power drift of the device under test in the batch process. The minimum distance of probe sensors to surface determines the closest measurement point to phantom surface. This distance cannot be smaller than the distance of sensor calibration points to probe tip as defined in the probe properties.
Report No.: CTA24040900105
Area Scan Procedures
Page 24 of 69
The area scan is used as a fast scan in two dimensions to find the area of high field values, before doing a fine measurement around the hot spot. The sophisticated interpolation routines implemented in DASY software can find the maximum found in the scanned area, within a range of the global maximum. The range (in dB0 is specified in the standards for compliance testing. For example, a 2 dB range is required in IEEE standard 1528 and IEC 62209 standards, whereby 3 dB is a requirement when compliance is assessed in accordance with the ARIB standard (Japan), if only one zoom scan follows the area scan, then only the absolute maximum will be taken as reference. For cases where multiple maximums are detected, the number of zoom scans has to be increased accordingly. Area scan parameters extracted from FCC KDB 865664 D01 SAR measurement 100 MHz to 6 GHz.
Zoom Scan Procedures
Zoom scans are used assess the peak spatial SAR values within a cubic averaging volume containing 1 gram and 10gram of simulated tissue. The zoom scan measures points (refer to table below) within a cube shoes base faces are centered on the maxima found in a preceding area scan job within the same procedure. When the measurement is done, the zoom scan evaluates the averaged SAR for 1 gram and 10 gram and displays these values next to the job's label. Zoom scan parameters extracted from FCC KDB 865664 D01 SAR measurement 100 MHz to 6 GHz.
Report No.: CTA24040900105
Volume Scan Procedures
Page 25 of 69
The volume scan is used for assess overlapping SAR distributions for antennas transmitting in different frequency bands. It is equivalent to an oversized zoom scan used in standalone measurements. The measurement volume will be used to enclose all the simultaneous transmitting antennas. For antennas transmitting simultaneously in different frequency bands, the volume scan is measured separately in each frequency band. In order to sum correctly to compute the 1g aggregateSAR, the EUT remain in the same test position for all measurements and all volume scan use the same spatial resolution and grid spacing. When all volume scan were completed, the software, SEMCAD postprocessor can combine and subsequently superpose these measurement data to calculating the multiband SAR.
Power Drift Monitoring
All SAR testing is under the EUT install full charged battery and transmit maximum output power. In DASY measurement software, the power reference measurement and power drift measurement procedures are used for monitoring the power drift of EUT during SAR test. Both these procedures measure the field at a specified reference position before and after the SAR testing. The software will calculate the field difference in dB. If the power drift more than 5%, the SAR will be retested.

SAR Test Exclusion and Estimated SAR
Page 29 of 69
SAR Test Exclusion Considerations Per KDB 447498 D01v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[f(GHz)] 3.0 for 1-g SAR and 7.5 for 10-g extremity SAR f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation. The result is rounded to one decimal place for comparison.
Per KDB 447498 D01v06, at 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following: a) [Threshold at 50mm)+(test separation distance-50mm)*(f(MHz)/150)]mW, at 100MHz to 1500MHz b) [Threshold at 50mm)+(test separation distance-50mm)*10]mW at > 1500MHz and 6GHz
Estimated SAR Per KDB447498 requires when the standalone SAR test exclusion of section 4.3.1 is applied to an antenna that transmits simultaneously with other antennas, the standalone SAR must be estimated according to the following to determine simultaneous transmission SAR test exclusion; (max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[ f(GHz)/x] W/kg for test separation distances 50 mm; where x = 7.5 for 1-g SAR, and x = 18.75 for 10-g SAR. 0.4 W/kg for 1-g SAR and 1.0 W/kg for 10-g SAR, when the test separation distances is > 50 mm

SAR Test Results
General Note:
1 Per KDB 447498 D01v06, the reported SAR is the measured SAR value adjusted for maximum tune-up
tolerance.
a) Tune-up scaling Factor = tune-up limit power (mW) / EUT RF power (mW), where tune-up limit is the
maximum rated power among all production units.
b) For SAR testing of WLAN signal with non-100% duty cycle, the measured SAR is scaled-up by the
duty cycle scaling factor which is equal to "1/ (duty cycle)"
c) For WLAN/Bluetooth: Reported SAR(W/kg)= Measured SAR(W/kg)* Duty Cycle scaling factor * Tune-
up scaling factor
2 Per KDB 447498 D01v06, for each exposure position, 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
3 Per KDB 865664 D01v01r04, for each frequency band, repeated SAR measurement is required only when
the measured SAR is 0.8W/kg.

SAR Measurement Variability
Page 33 of 69
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. When both head and body tissue-equivalent media are required for SAR measurements in a frequency band, the variability measurement procedures should be applied to the tissue medium with the highest measured SAR, using
the highest measured SAR configuration for that tissue-equivalent medium. The following procedures are
applied to determine if repeated measurements are required.
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.
