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.
10.2. 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.
10.3. Area Scan Procedures
Area scans are defined prior to the measurement process being executed with a user defined
variable spacing between each measurement point (integral) allowing low uncertainty measurements
to be conducted. Scans defined for FCC applications utilize a10mm² step integral, with 1mm
interpolation used to locate the peak SAR area used for zoom scan assessments.
When an Area Scan has measured all reachable points, it computes the field maxima founding 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 IEEE1528-2003.
10.4. Zoom Scan Procedures
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. A density of 1000 kg/m³ is used to represent the head
and body tissue density and not the phantom liquid density, in order to be consistent with the
definition of the liquid dielectric properties, i.e. the side length of the 1g cube is 10mm, with the side
