2. REQUIREMENTS FOR COMPLIANCE TESTING DEFINED BY THE FCC
     The US Federal Communications Commission has released the report and order “Guidelines for
     Evaluating the Environmental Effects of RF Radiation", ET Docket No. 93-62 in August 1996 [1]. The
     order requires routine SAR evaluation prior to equipment authorization of portable transmitter
     devices, including portable telephones. For consumer products, the applicable limit is 1.6 mW/g for
     an uncontrolled environment and 8.0 mW/g for an occupational/controlled environment as
     recommended by the ANSI/IEEE standard C95.1-1992 [6]. According to the Supplement C of OET
     Bulletin 65 “Evaluating Compliance with FCC Guide-lines for Human Exposure to Radio frequency
     Electromagnetic Fields", released on Jun 29, 2001 by the FCC, the device should be evaluated at
     maximum output power (radiated from the antenna) under “worst-case” conditions for normal or
     intended use, incorporating normal antenna operating positions, device peak performance
     frequencies and positions for maximum RF energy coupling.
3. DOSIMETRIC ASSESSMENT SYSTEM
     These measurements were performed with the automated near-field scanning system DASY4 from
     Schmid & Partner Engineering AG (SPEAG). The system is based on a high precision robot (working
     range greater than 0.9 m) which positions the probes with a positional repeatability of better than ±
     0.02 mm. Special E- and H-field probes have been developed for measurements close to material
     discontinuity, the sensors of which are directly loaded with a Schottky diode and connected via highly
     resistive lines to the data acquisition unit. The SAR measurements were conducted with the
     dosimetric probe ES3DV2-SN: 3021 (manufactured by SPEAG), designed in the classical triangular
     configuration and optimized for dosimetric evaluation. The probe has been calibrated according to
     the procedure with accuracy of better than ±10%. The spherical isotropy was evaluated with the
     procedure and found to be better than ±0.25 dB. The phantom used was the SAM Twin Phantom as
     described in FCC supplement C, IEEE P1528 and EN50361.

     3.1. MEASUREMENT SYSTEM DIAGRAM




           The DASY4 system for performing compliance tests consists of the following items:
           •   A standard high precision 6-axis robot (St¨aubli RX family) with controller, teach pendant
               and software. An arm extension for accommodating the data acquisition electronics (DAE).
           •   A dosimetric probe, i.e., an isotropic E-field probe optimized and calibrated for usage in
               tissue simulating liquid. The probe is equipped with an optical surface detector system.
           •   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 between optical and electrical
               of the signals for the digital communication to the DAE and for the analog signal from the
               optical surface detection. The EOC is connected 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.
           •   A probe alignment unit which improves the (absolute) accuracy of the probe positioning.
           •   A computer operating Windows 2000 or Windows XP.
           •   DASY4 software.
           •   Remote control with teach pendant and additional circuitry for robot safety such as warning
               lamps, etc.
           •   The SAM twin phantom enabling testing left-hand and right-hand usage.
           •   The device holder for handheld mobile phones.
           •   Tissue simulating liquid mixed according to the given recipes.
           •   Validation dipole kits allowing validating the proper functioning of the system.

     3.2. SYSTEM COMPONENTS
     DASY4 Measurement Server
                                          The DASY4 measurement server is based on a PC/104 CPU
                                          board with a 166MHz low-power Pentium, 32MB chip disk and
                                          64MB RAM. The necessary circuits for communication with
                                          either the DAE3 electronic box as well as the 16-bit AD-converter
                                          system for optical detection and digital I/O interface are contained
                                          on the DASY4 I/O-board, which is directly connected to the
                                          PC/104 bus of the CPU board.
                                          The measurement server performs all real-time data evaluation
     for 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 two expansion slots which are
     reserved for future applications. Please note that the expansion slots do not have a standardized
     pinout and therefore only the expansion cards provided by SPEAG can be inserted. Expansion cards
     from any other supplier could seriously damage the measurement server. Calibration: No calibration
     required.
     Data Acquisition Electronics (DAE)
     The data acquisition electronics (DAE3) consists 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 and 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 DAE3
     box is 200MOhm; the inputs are symmetrical and floating. Common mode rejection is above 80 dB.

4. 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              ConvF i
                                   - Diode compression point dcp i
            Device parameters: - Frequency                          f
                                   - Crest factor                   cf
            Media parameters: - Conductivity                        σ
                                   - Density                        r
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

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 10 mm by 10 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 7 x 7 x 8 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.

7. MEASUREMENT RESULTS
   7.1. SYSTEM PERFORMANCE CHECK
     The system performance check is performed prior to any usage of the system in order to guarantee
     reproducible results. The system performance check verifies that the system operates within its
     specifications. The system performance check results are tabulated below. And also the
     corresponding SAR plot is attached as well in the SAR plots files.
     SYSTEM PERFORMANCE CHECK MEASUREMENT CONDITIONS
     •    The measurements were performed in the flat section of the SAM twin phantom filled with Body
          simulating liquid of the following parameters.
     •    The DASY4 system with an Isotropic E-Field Probe ES3DV2-SN: 3021 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)
          from dipole center to the simulating liquid surface.
     •    The coarse grid with a grid spacing of 10mm was aligned with the dipole.
     •    Special 7x7x8 fine cube was chosen for cube integration (dx=dy= 4.3 mm, dz= 3 mm).
     •    Distance between probe sensors and phantom surface was set to 3.0 mm.
     •    The dipole input power (forward power) was 250 mW ±3%.
     •    The results are normalized to 1 W input power.

    7.2. 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
     TISSUE SIMULATING LIQUIDS
     In the current guidelines and draft standards for compliance testing of mobile phones (e.., IEEE
     P1528, OET 65 Supplement C), the dielectric parameters suggested for head and body tissue
     simulating liquid are given only at 3.0 GHz and 5.8 GHz. As an intermediate solution, dielectric
     parameters for the frequencies between 5 to 5.8 GHz were obtained using linear interpolation (see
     table below).
     SPEAG has developed suitable head and body tissue simulating liquids consisting of the following
     ingredients: de-ionized water, salt and a special composition including mineral oil and an emulgators.
     Dielectric parameters of these liquids were measured suing a HP 8570C Dielectric Probe Kit in
     conjunction with HP 8753ES Network Analyzer (30 kHz – 6G Hz). The differences with respect to the
     interpolated values were well within desired ±5% for the whole 5 to 5.8 GHz range.

    7.3. EUT TUNE-UP PROCEDURES
         The following procedures had been used to prepare the EUT for the SAR test.
         o The client supplied a special driving program (CRTU v1.2.0.3000) to program the EUT to
             continually transmit the specified maximum power. And also to change the channel
             frequency.
             Power control:
             EERPROM DEFAULT = 0
             TPC = 0
             TDA = 226
             TXFILTER = 38
             DSP = 88 (5180 MHz and 5260 MHz)
                   = 103 (5320 MHz)
         o The conducted power was measured at the high, middle and low channel frequency before
             and after the SAR measurement.
