5. EVALUATION PROCEDURES

DATA EVALUATION
The DASY4 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 σ
- Density ρ
These parameters must be set correctly in the software. They can be found in the component documents or 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:
2 cf
V =U +U
i i i
⋅
dcp i

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:

SAR MEASUREMENT PROCEDURES
The procedure for assessing the peak spatial-average SAR value consists of the following steps:
• Power Reference Measurement
The reference and drift jobs are useful jobs for monitoring the power drift of the device under test in the batch
process. Both jobs measure the field at a specified reference position, at a selectable distance from the phantom
surface. The reference position can be either the selected section’s grid reference point or a user point in this
section. The reference job projects the selected point onto the phantom surface, orients the probe
perpendicularly to the surface, and approaches the surface using the selected detection method.
• 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 finer
measurement around the hot spot. The sophisticated interpolation routines implemented in DASY4 software can
find the maximum locations even in relatively coarse grids. The scan area is defined by an editable grid. This
grid is anchored at the grid reference point of the selected section in the phantom. When the area scan’s
property sheet is brought-up, grid was at to 15 mm by 15 mm and can be edited by a user.
• 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 default zoom scan measures 5x5x7(for 2.45GHz) and 8x8x8(for 5GHz)points
within a cube whose base faces are centered around the maximum found in a preceding area scan job within the
same procedure. If the preceding Area Scan job indicates more then one maximum, the number of Zoom Scans
has to be enlarged accordingly (The default number inserted is 1).
• Power Drift measurement
The drift job measures the field at the same location as the most recent reference job within the same procedure,
and with the same settings. The drift measurement gives the field difference in dB from the reading conducted
within the last reference measurement. Several drift measurements are possible for one reference measurement.
This allows a user to monitor the power drift of the device under test within a batch process. In the properties
of the Drift job, the user can specify a limit for the drift and have DASY4 software stop the measurements if
this limit is exceeded.
• Z-Scan
The Z Scan job measures points along a vertical straight line. The line runs along the Z-axis of a one-
dimensional grid. A user can anchor the grid to the current probe location. As with any other grids, the local Z-
axis of the anchor location establishes the Z-axis of the grid.

9.2 TEST LIQUID CONFIRMATION
SIMULATING LIQUIDS PARAMETER CHECK
The simulating liquids should be checked at the beginning of a series of SAR measurements to determine of the
dielectric parameters are within the tolerances of the specified target values
The relative permittivity and conductivity of the tissue material should be within ± 5% of the values given in the
table below. 5% may not be easily achieved at certain frequencies. Under such circumstances, 10% tolerance
may be used until more precise tissue recipes are available
IEEE SCC-34/SC-2 P1528 RECOMMENDED TISSUE DIELECTRIC PARAMETERS
The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in P1528 have been
incorporated in the following table. These head parameters are derived from planar layer models simulating the
highest expected SAR for the dielectric properties and tissue thickness variations in a human head. Other head
and body tissue parameters that have not been specified in P1528 are derived from the tissue dielectric
parameters computed from the 4-Cole-Cole equations and extrapolated according to the head parameters
specified in P1528
