A standard high precision 6-axis robot (Stäubli TX=RX family) 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 and the DASY4 or DASY5 software.

C.2 Dasy4 or DASY5 E-field Probe System
The SAR measurements were conducted with the dosimetric probe designed in the classical
triangular configuration and optimized for dosimetric evaluation. The probe is constructed using the
thick film technique; with printed resistive lines on ceramic substrates. The probe is equipped with
an optical multifiber line ending at the front of the probe tip. It is connected to the EOC box on the
robot arm and provides an automatic detection of the phantom surface. Half of the fibers are
connected to a pulsed infrared transmitter, the other half to a synchronized receiver. As the probe
approaches the surface, the reflection from the surface produces a coupling from the transmitting to
the receiving fibers. This reflection increases first during the approach, reaches maximum and then
decreases. If the probe is flatly touching the surface, the coupling is zero. The distance of the
coupling maximum to the surface is independent of the surface reflectivity and largely independent
of the surface to probe angle. The DASY4 or DASY5 software reads the reflection durning a software
approach and looks for the maximum using 2nd ord curve fitting. The approach is stopped at reaching
the maximum.

C.3 E-field Probe Calibration
Each E-Probe/Probe Amplifier combination has unique calibration parameters. A TEM cell
calibration procedure is conducted to determine the proper amplifier settings to enter in the probe
parameters. The amplifier settings are determined for a given frequency by subjecting the probe to
a known E-field density (1 mW/cm2) using an RF Signal generator, TEM cell, and RF Power Meter.
The free space E-field from amplified probe outputs is determined in a test chamber. This
calibration can be performed in a TEM cell if the frequency is below 1 GHz and inn a waveguide or
other methodologies above 1 GHz for free space. For the free space calibration, the probe is placed

in the volumetric center of the cavity and at the proper orientation with the field. The probe is then
rotated 360 degrees until the three channels show the maximum reading. The power density
readings equates to 1 mW/ cm2..
E-field temperature correlation calibration is performed in a flat phantom filled with the appropriate
simulated brain tissue. The E-field in the medium correlates with the temperature rise in the dielectric
medium. For temperature correlation calibration a RF transparent thermistor-based temperature
probe is used in conjunction with the E-field probe.

C.4 Other Test Equipment
C.4.1 Data Acquisition Electronics(DAE)
The data acquisition electronics consist of a highly sensitive electrometer-grade preamplifier with
auto-zeroing, a channel and gain-switching multiplexer, a fast 16 bit AD-converter and a command
decoder with a control logic unit. Transmission to the measurement server is accomplished through
an optical downlink for data and status information, as well as an optical uplink for commands and
the clock.
The mechanical probe mounting device includes two different sensor systems for frontal and
sideways probe contacts. They are used for mechanical surface detection and probe collision
detection.
The input impedance of the DAE is 200 MOhm; the inputs are symmetrical and floating. Common
mode rejection is above 80 dB.

C.4.2 Robot
The SPEAG DASY system uses the high precision robots (DASY4: RX90XL; DASY5: RX160L) type
from Stäubli SA (France). For the 6-axis controller system, the robot controller version from Stäubli
is used. The Stäubli robot series have many features that are important for our application:
 High precision (repeatability 0.02mm)
 High reliability (industrial design)
 Low maintenance costs (virtually maintenance free due to direct drive gears; no belt drives)
 Jerk-free straight movements (brushless synchron motors; no stepper motors)
 Low ELF interference (motor control fields shielded via the closed metallic construction
shields)
Picture C.5 DASY 4
Picture C.6 DASY 5
C.4.3 Measurement Server
The Measurement server is based on a PC/104 CPU broad with CPU (dasy4: 166 MHz, Intel Pentium;
DASY5: 400 MHz, Intel Celeron), chipdisk (DASY4: 32 MB; DASY5: 128MB), RAM (DASY4: 64 MB,
DASY5: 128MB). The necessary circuits for communication with the DAE electronic box, as well as
the 16 bit AD converter system for optical detection and digital I/O interface are contained on the
DASY I/O broad, which is directly connected to the PC/104 bus of the CPU broad.
The measurement server performs all real-time data evaluation of field measurements and surface
detection, controls robot movements and handles safety operation. The PC operating system cannot
interfere with these time critical processes. All connections are supervised by a watchdog, and
disconnection of any of the cables to the measurement server will automatically disarm the robot and
disable all program-controlled robot movements. Furthermore, the measurement server is equipped
with an expansion port which is reserved for future applications. Please note that this expansion port
does not have a standardized pinout, and therefore only devices provided by SPEAG can be
connected. Devices from any other supplier could seriously damage the measurement server.

C.4.4 Device Holder for Phantom
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 5mm 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 the different positions given in the standard. It
has two scales for device rotation (with respect to the body axis) and device inclination (with
respect to the line between the ear reference points). The rotation centers for both scales is the ear
reference point (ERP). Thus the device needs no repositioning when changing the angles.
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.

The extension is lightweight and made of POM, acrylic glass and foam. It fits easily on the upper
part of the Mounting Device in place of the phone positioner. The extension is fully compatible with
the Twin-SAM and ELI phantoms.

C.4.5 Phantom
The SAM Twin Phantom V4.0 is constructed of a fiberglass shell integrated in a table. The shape of
the shell is based on data from an anatomical study designed to
Represent the 90th percentile of the population. The phantom enables the dissymmetric evaluation
of SAR for both left and right handed handset usage, as well as body-worn usage using the flat
phantom region. Reference markings on the Phantom allow the complete setup of all predefined
phantom positions and measurement grids by manually teaching three points in the robot. The shell
phantom has a 2mm shell thickness (except the ear region where shell thickness increases to 6 mm).
