4. SAR Measurement System & Test Equipment
4.1.    SAR Measurement System
The DASY5 system used for performing compliance tests consists of the following items:




   A standard high precision 6-axis robot with controller, teach pendant and software. An arm extension for
    accommodating the data acquisition electronics (DAE).
   An isotropic Field probe optimized and calibrated for the targeted measurement.
   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 from optical to electrical signals for the digital
    communication to the DAE. To use optical surface detection, a special version of the EOC is required. The
    EOC signal is transmitted to the measurement server.
   The function of the measurement server is to perform the time critical tasks such as signal filtering, control of
    the robot operation and fast movement interrupts.
   The Light Beam used is for probe alignment. This improves the (absolute) accuracy of the probe positioning.
   A computer running WinXP or Win7 and the DASY5 software.
   Remote control and teach pendant as well as additional circuitry for robot safety such as warning lamps, etc.
   The phantom, the device holder and other accessories according to the targeted measurement.

4.2. SAR Scan Procedures
Step 1: 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. The minimum distance of probe sensors to surface is 2.1 mm. This
distance cannot be smaller than the distance of sensor calibration points to probe tip as defined in the probe
properties.

Step 2: Area Scan
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 locations even in relatively coarse grids. When an Area Scan has measured all reachable points, it
computes the field maximal found in the scanned area, within a range of the global maximum. The range (in dB) 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.

Step 3: Zoom Scan
Zoom Scans are used to assess the peak spatial SAR values within a cubic averaging volume containing 1 g and
10 g of simulated tissue. The Zoom Scan measures points (refer to table below) within a cube whose 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 g and 10 g and displays these values
next to the job’s label.

Step 4: Power drift measurement
The Power Drift Measurement measures the field at the same location as the most recent power reference
measurement within the same procedure, and with the same settings. The Power Drift Measurement gives the field
difference in dB from the reading conducted within the last Power Reference Measurement. This allows a user to
monitor the power drift of the device under test within a batch process. The measurement procedure is the same as
Step 1.

Step 5: Z-Scan (FCC only)
The Z Scan measures points along a vertical straight line. The line runs along the Z-axis of a one-dimensional grid.
In order to get a reasonable extrapolation the extrapolated distance should not be larger than the step size in Z-
direction.

 Spectrum plots for RB configurations       A properly configured base station simulator was used for the SAR and power measurements;
                                            therefore, spectrum plots for each RB allocation and offset configuration are not included in the
                                            SAR report.



7. RF Exposure Conditions (Test Configurations)

8. Dielectric Property Measurements & System Check
8.1.    Dielectric Property Measurements
The temperature of the tissue-equivalent medium used during measurement must also be within 18C to 25C and
within ± 2C of the temperature when the tissue parameters are characterized.
The dielectric parameters must be measured before the tissue-equivalent medium is used in a series of SAR
measurements. The parameters should be re-measured after each 3 – 4 days of use; or earlier if the dielectric
parameters can become out of tolerance; for example, when the parameters are marginal at the beginning of the
measurement series.
Tissue dielectric parameters were measured at the low, middle and high frequency of each operating frequency
range of the test device.

8.2.      System Check
SAR system verification is required to confirm measurement accuracy, according to the tissue dielectric media,
probe calibration points and other system operating parameters required for measuring the SAR of a test device.
The system verification must be performed for each frequency band and within the valid range of each probe
calibration point required for testing the device. The same SAR probe(s) and tissue-equivalent media combinations
used with each specific SAR system for system verification must be used for device testing. When multiple probe
calibration points are required to cover substantially large transmission bands, independent system verifications are
required for each probe calibration point. A system verification must be performed before each series of SAR
measurements using the same probe calibration point and tissue-equivalent medium. Additional system verification
should be considered according to the conditions of the tissue-equivalent medium and measured tissue dielectric
parameters, typically every three to four days when the liquid parameters are re-measured or sooner when
marginal liquid parameters are used at the beginning of a series of measurements.

System Performance Check Measurement Conditions:
     The measurements were performed in the flat section of the TWIN SAM or ELI phantom, shell thickness: 2.0
      ±0.2 mm (bottom plate) filled with Body or Head simulating liquid of the following parameters.
     The depth of tissue-equivalent liquid in a phantom must be ≥ 15.0 cm for SAR measurements ≤ 3 GHz and ≥
      10.0 cm for measurements > 3 GHz.
     The DASY system with an E-Field Probe was used for the measurements.
     The dipole was mounted on the small tripod so that the dipole feed point was positioned below the center
      marking of the flat phantom section and the dipole was oriented parallel to the body axis (the long side of the
      phantom). The standard measuring distance was 10 mm (above 1 GHz) and 15 mm (below 1 GHz) from dipole
      center to the simulating liquid surface.
     The coarse grid with a grid spacing of 15 mm was aligned with the dipole.
      For 5 GHz band - The coarse grid with a grid spacing of 10 mm was aligned with the dipole.
     Special 7x7x7 (below 3 GHz) and/or 8x8x7 (above 3 GHz) fine cube was chosen for the cube.
     Distance between probe sensors and phantom surface was set to 3 mm.
      For 5 GHz band - Distance between probe sensors and phantom surface was set to 2.5 mm
     The dipole input power (forward power) was 100 mW.
     The results are normalized to 1 W input power.

10.     Measured and Reported (Scaled) SAR Results
SAR Test Reduction criteria are as follows:

KDB 447498 D01 General RF Exposure Guidance:
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

KDB 941225 D05 SAR for LTE Devices:
SAR test reduction is applied using the following criteria:
  Start with the largest channel bandwidth and measure SAR for QPSK with 1 RB, and 50% RB allocation, using the RB
   offset and required test channel combination with the highest maximum output power among RB offsets at the upper edge,
   middle and lower edge of each required test channel.
  When the reported SAR is > 0.8/2 W/kg, 1-g and 10-g respectively, testing for other Channels is performed at the highest
   output power level for 1RB, and 50% RB configuration for that channel.
  Testing for 100% RB configuration is performed at the highest output power level for 100% RB configuration across the
   Low, Mid and High Channel when the highest reported SAR for 1 RB and 50% RB are > 0.8/2 W/kg, 1-g and 10-g
   respectively. Testing for the remaining required channels is not needed because the reported SAR for 100% RB Allocation
   < 1.45/3.625 W/kg, 1-g and 10-g respectively.
  Testing for 16-QAM modulation is not required because the reported SAR for QPSK is < 1.45/3.625 W/Kg, 1-g and 10-g
   respectively, and its output power is not more than 0.5 dB higher than that of QPSK.
  Testing for the other channel bandwidths is not required because the reported SAR for the highest channel bandwidth is <
   1.45/3.625 W/Kg, 1-g and 10-g respectively, and its output power is not more than 0.5 dB higher than that of the highest
   channel bandwidth.
  For LTE bands that do not support at least three non-overlapping channels in certain channel bandwidths, test the available
   non-overlapping channels instead. When a device supports overlapping channel assignment in a channel bandwidth
   configuration, the middle channel of the group of overlapping channels should be selected for testing; therefore, the
   requirement for H, M and L channels may not fully apply.

Report No.: 15I21799-S1V2                                                                                     Issue Date: 9/30/2015
KDB 248227 D01 SAR meas for 802.11:
SAR test reduction for 802.11 Wi-Fi transmission mode configurations are considered separately for DSSS and OFDM. An initial
test position is determined to reduce the number of tests required for certain exposure configurations with multiple test positions.
An initial test configuration is determined for each frequency band and aggregated band according to maximum output power,
channel bandwidth, wireless mode configurations and other operating parameters to streamline the measurement requirements.
For 2.4 GHz DSSS, either the initial test position or DSSS procedure is applied to reduce the number of SAR tests; these are
mutually exclusive. For OFDM, an initial test position is only applicable to next to the ear, UMPC mini-tablet and hotspot mode
configurations, which is tested using the initial test configuration to facilitate test reduction. For other exposure conditions with a
fixed test position, SAR test reduction is determined using only the initial test configuration.
     The multiple test positions require SAR measurements in head, hotspot mode or UMPC mini-tablet configurations may be
reduced according to the highest reported SAR determined using the initial test position(s) by applying the DSSS or OFDM SAR
measurement procedures in the required wireless mode test configuration(s). The initial test position(s) is measured using the
highest measured maximum output power channel in the required wireless mode test configuration(s). When the reported SAR
for the initial test position is:

        ≤ 0.4/1 W/kg, 1-g and 10-g respectively, further SAR measurement is not required for the other test positions in that
         exposure configuration and wireless mode combination within the frequency band or aggregated band. DSSS and
         OFDM configurations are considered separately according to the required SAR procedures.
        > 0.4/1 W/kg, 1-g and 10-g respectively, SAR is repeated using the same wireless mode test configuration tested in the
         initial test position to measure the subsequent next closet/smallest test separation distance and maximum coupling test
         position, on the highest maximum output power channel, until the reported SAR is ≤ 0.8/2 W/kg, 1-g and 10-g
         respectively, or all required test positions are tested.
         o For subsequent test positions with equivalent test separation distance or when exposure is dominated by coupling
               conditions, the position for maximum coupling condition should be tested.
         o When it is unclear, all equivalent conditions must be tested.
        For all positions/configurations tested using the initial test position and subsequent test positions, when the reported
         SAR is > 0.8/2 W/kg, 1-g and 10-g respectively, measure the SAR for these positions/configurations on the subsequent
         next highest measured output power channel(s) until the reported SAR is ≤ 1.2/3 W/kg, 1-g and 10-g respectively, or all
         required test channels are considered.
         o The additional power measurements required for this step should be limited to those necessary for identifying
               subsequent highest output power channels to apply the test reduction.
        When the specified maximum output power is the same for both UNII 1 and UNII 2A, begin SAR measurements in UNII
         2A with the channel with the highest measured output power. If the reported SAR for UNII 2A is ≤ 1.2/3 W/kg, 1-g and
         10-g respectively, SAR is not required for UNII 1; otherwise treat the remaining bands separately and test them
         independently for SAR.
        When the specified maximum output power is different between UNII 1 and UNII 2A, begin SAR with the band that has
         the higher specified maximum output. If the highest reported SAR for the band with the highest specified power is ≤
         1.2/3 W/kg, 1-g and 10-g respectively, testing for the band with the lower specified output power is not required;
         otherwise test the remaining bands independently for SAR.

     To determine the initial test position, Area Scans were performed to determine the position with the Maximum Value of SAR
(measured). The position that produced the highest Maximum Value of SAR is considered the worst case position; thus used as
the initial test position.

10.3. Standalone SAR Test Exclusion Considerations & Estimated SAR
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, where
         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
The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for
transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a
distance of 5 mm is applied to determine SAR test exclusion.

When the standalone SAR test exclusion is applied to an antenna that transmits simultaneously with other
antennas, the standalone SAR must be estimated according to 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.

11.        SAR Measurement Variability
In accordance with published RF Exposure KDB 865664 D01 SAR measurement 100 MHz to 6 GHz. These
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 <1.6 or 2 W/kg (1-g or 10-g
   respectively); steps 2) through 4) do not apply.
2) When the original highest measured SAR is ≥ 0.8 or 2 W/kg (1-g or 10-g respectively), 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 3 (1-g or 10-g respectively) or when the original or repeated measurement
   is ≥ 1.45 or 3.6 W/kg (~ 10% from the 1-g or 10-g respective SAR limit).
4) Perform a third repeated measurement only if the original, first, or second repeated measurement is ≥ 1.5 or
   3.75 W/kg (1-g or 10-g respectively) and the ratio of largest to smallest SAR for the original, first and second
   repeated measurements is > 1.20 or 3 (1-g or 10-g respectively).

Conclusion:
Simultaneous transmission SAR measurement (Volume Scan) is not required because the either sum of the 1-g SAR is <
1.6/4.0 W/kg, 1-g and 10-g respectively, or the SPLSR is ≤ 0.04 for 1-g and ≤ 0.10 for 10-g for all circumstances that require
SPLSR calculation.
