          American National Standard, Methods of Measurement of Compatibility between Wireless Communications
          Devices and Hearing Aids.
Methods Applied and Interpretation of Parameters:
      •   Coordinate System: y-axis is in the direction of the dipole arms. z-axis is from the basis of the antenna
          (mounted on the table} towards its feed point between the two dipole arms. x-axis is normal to the other axes.
          In coincidence with the standards [1 ], the measurement planes (probe sensor center) are selected to be at a
          distance of 15 mm above the top metal edge of the dipole arms.
      •   Measurement Conditions: Further details are available from the hardcopies at the end of the certificate. All
          figures stated in the certificate are valid at the frequency indicated. The forward power to the dipole connector
          is set with a calibrated power meter connected and monitored with an auxiliary power meter connected to a
          directional coupler. While the dipole under test is connected, the forward power is adjusted to the same level.
      •   Antenna Positioning: The dipole is mounted on a HAC Test Arch phantom using the matching dipole
          positioner with the arms horizontal and the feeding cable coming from the floor. The measurements are
          performed in a shielded room with absorbers around the setup to reduce the reflections.
          It is verified before the mounting of the dipole under the Test Arch phantom , that its arms are perfectly in a
          line. It is installed on the HAC dipole positioner with its arms parallel below the dielectric reference wire and
          able to move elastically in vertical direction without changing its relative position to the top center of the Test
          Arch phantom. The vertical distance to the probe is adjusted after dipole mounting with a DASY5 Surface
          Check job. Before the measurement, the distance between phantom surface and probe tip is verified. The
          proper measurement distance is selected by choosing the matching section of the HAC Test Arch phantom
          with the proper device reference point (upper surface of the dipole) and the matching grid reference point (tip
          of the probe) considering the probe sensor offset. The vertical distance to the probe is essential for the
          accuracy.
      •   Feed Point Impedance and Return Loss: These parameters are measured using a HP 8753E Vector Network
          Analyzer. The impedance is specified at the SMA connector of the dipole. The influence of reflections was
          eliminating by applying the averaging function while moving the dipole in the air, at least 70cm away from any
          obstacles.
      •   E-tield distribution: E field is measured in the x-y-plane with an isotropic ER3D-field probe with 100 mW
          forward power to the antenna feed point. In accordance with [1 ], the scan area is 20mm wide, its length
          exceeds the dipole arm length (180 or 90mm). The sensor center is 15 mm (in z) above the metal top of the
          dipole arms. Two 30 maxima are available near the end of the dipole arms. Assuming the dipole arms are
          perfectly in one line, the average of these two maxima (in subgrid 2 and subgrid 8) is determined to
          compensate for any non-parallelity to the measurement plane as well as the sensor displacement. The E-field
          value stated as calibration value represents the maximum of the interpolated 30-E-field, in the plane above
          the dipole surface.




 The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the
 coverage factor k=2, which for a normal distribution corresponds to a coverage probability of approximately 95%.

3.2 Antenna Design and Handling

The calibration dipole has a symmetric geometry with a built-in two stub matching network, which leads to the
enhanced bandwidth.
The dipole is built of standard semi rigid coaxial cable. The internal matching line is open ended. The antenna is
therefore open for DC signals.
Do not apply force to dipole arms, as they are liable to bend. The soldered connections near the feedpoint may be
damaged. After excessive mechanical stress or overheating, check the impedance characteristics to ensure that the
internal matching network is not affected.

After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be measured.

          American National Standard, Methods of Measurement of Compatibility between Wireless Communications
          Devices and Hearing Aids.
Methods Applied and Interpretation of Parameters:
      •   Coordinate System: y-axis is in the direction of the dipole arms. z-axis is from the basis of the antenna
          (mounted on the table) towards its teed point between the two dipole arms. x-axis is normal to the other axes.
          In coincidence with the standards [1], the measurement planes (probe sensor center) are selected to be at a
          distance of 15 mm above the top metal edge of the dipole arms.
      •   Measurement Conditions: Further details are available from the hardcopies at the end of the certificate. All
          figures stated in the certificate are valid at the frequency indicated. The forward power to the dipole connector
          is set with a calibrated power meter connected and monitored with an auxiliary power meter connected to a
          directional coupler. While the dipole under test is connected, the forward power is adjusted to the same level.
      •   Antenna Positioning: The dipole is mounted on a HAC Test Arch phantom using the matching dipole
          positioner with the arms horizontal and the feeding cable coming from the floor. The measurements are
          performed in a shielded room with absorbers around the setup to reduce the reflections.
          It is verified before the mounting of the dipole under the Test Arch phantom, that its arms are perfectly in a
          line. It is installed on the HAC dipole positioner with its arms parallel below the dielectric reference wire and
          able to move elastically in vertical direction without changing its relative position to the top center of the Test
          Arch phantom. The vertical distance to the probe is adjusted after dipole mounting with a DASY5 Surface
          Check job. Before the measurement, the distance between phantom surface and probe tip is verified. The
          proper measurement distance is selected by choosing the matching section of the HAC Test Arch phantom
          with the proper device reference point (upper surface of the dipole) and the matching grid reference point (tip
          of the probe) considering the probe sensor offset. The vertical distance to the probe is essential tor the
          accuracy.
      •   Feed Point Impedance and Return Loss: These parameters are measured using a HP 8753E Vector Network
          Analyzer. The impedance is specified at the SMA connector of the dipole. The influence of reflections was
          eliminating by applying the averaging function while moving the dipole in the air, at least 70cm away from any
          obstacles.
      •   E-field distribution: E field is measured in the x-y-plane with an isotropic ER3D-field probe with 100 mW
          forward power to the antenna feed point. In accordance with [1 J, the scan area is 20mm wide, its length
          exceeds the dipole arm length (180 or 90mm). The sensor center is 15 mm (in z) above the metal top of the
          dipole arms. Two 3D maxima are available near the end of the dipole arms. Assuming the dipole arms are
          perfectly in one line, the average of these two maxima (in subgrid 2 and subgrid 8) is determined to
          compensate for any non-parallelity to the measurement plane as well as the sensor displacement. The E-field
          value stated as calibration value represents the maximum of the interpolated 3D-E-field, in the plane above
          the dipole surface.




 The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the
 coverage factor k=2, which for a normal distribution corresponds to a coverage probability of approximately 95%.

3.2 Antenna Design and Handling

The calibration dipole has a symmetric geometry with a built-in two stub matching network, which leads to the
enhanced bandwidth.
The dipole is built of standard semirigid coaxial cable. The internal matching line is open ended. The antenna is
therefore open for DC signals.
Do not apply force to dipole arms, as they are liable to bend. The soldered connections near the feedpoint may be
damaged. After excessive mechanical stress or overheating, check the impedance characteristics to ensure that the
internal matching network is not affected.

After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be measured.

          Devices and Hearing Aids.
Methods Applied and Interpretation of Parameters:
      •   Coordinate System: y-axis is in the direction of the dipole arms. z-axis is from the basis of the antenna
          (mounted on the table} towards its feed point between the two dipole arms. x-axis is normal to the other axes.
          In coincidence with the standards [1], the measurement planes (probe sensor center) are selected to be at a
          distance of 15 mm above the top metal edge of the dipole arms.
      •   Measurement Conditions: Further details are available from the hardcopies at the end of the certificate. All
          figures stated in the certificate are valid at the frequency indicated. The forward power to the dipole connector
          is set with a calibrated power meter connected and monitored with an auxiliary power meter connected to a
          directional coupler. While the dipole under test is connected, the forward power is adjusted to the same level.
      •   Antenna Positioning:The dipole is mounted on a HAC Test Arch phantom using the matching dipole
          positioner with the arms horizontal and the feeding cable coming from the floor. The measurements are
          performed in a shielded room with absorbers around the setup to reduce the reflections.
          It is verified before the mounting of the dipole under the Test Arch phantom, that its arms are perfectly in a
          line. It is installed on the HAC dipole positioner with its arms parallel below the dielectric reference wire and
          able to move elastically in vertical direction without changing its relative position to the top center of the Test
          Arch phantom. The vertical distance to the probe is adjusted after dipole mounting with a DASY5 Surface
          Check job. Before the measurement, the distance between phantom surface and probe tip is verified. The
          proper measurement distance is selected by choosing the matching section of the HAC Test Arch phantom
          with the proper device reference point (upper surface of the dipole) and the matching grid reference point (tip
          of the probe} considering the probe sensor offset. The vertical distance to the probe is essential for the
          accuracy.
      •   Feed Point Impedance and Return Loss: These parameters are measured using a HP 8753E Vector Network
          Analyzer. The impedance is specified at the SMA connector of the dipole. The influence of reflections was
          eliminating by applying the averaging function while moving the dipole in the air, at least 70cm away from any
          obstacles.
      •   E-field distribution: E field is measured in the x-y-plane with an isotropic ER3D-field probe with 100 mW
          forward power to the antenna feed point. In accordance with (1 ], the scan area is 20mm wide, its length
          exceeds the dipole arm length ( 180 or 90mm). The sensor center is 15 mm (in z) above the metal top of the
          dipole arms. Two 30 maxima are available near the end of the dipole arms. Assuming the dipole arms are
          perfectly in one line, the average of these two maxima (in subgrid 2 and subgrid 8} is determined to
          compensate for any non-parallelity to the measurement plane as well as the sensor displacement. The E-field
          value stated as calibration value represents the maximum of the interpolated 3D-E-field, in the plane above
          the dipole surlace.




 The reported uncertainty of measurement is stated as the standard uncertainty of measurement multiplied by the
 coverage factor k=2, which for a normal distribution corresponds to a coverage probability of approximately 95%.

3.2 Antenna Design and Handling

The calibration dipole has a symmetric geometry with a built-in two stub matching network, which leads to the
enhanced bandwidth.
The dipole is built of standard semirigid coaxial cable. The internal matching line is open ended. The antenna is
therefore open for DC signals.
Do not apply force to dipole arms, as they are liable to bend. The soldered connections near the feedpoint may be
damaged. After excessive mechanical stress or overheating, check the impedance characteristics to ensure that the
internal matching network is not affected.

After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be measured.

Connector Angle              information used in DASY system to align probe sensor X to the robot coordinate system

Calibration is Performed According to the Following Standards:
    a) IEEE Std 1309-2005, " IEEE Standard for calibration of electromagnetic field sensors and probes, excluding
       antennas, from 9 kHz to 40 GHz", December 2005
    b) CTIA Test Plan for Hearing Aid Compatibility, Rev 3.1 .1, May 2017

Methods Applied and Interpretation of Parameters:
    •    NORMx,y, z: Assessed for E-field polarization S = 0 for XY sensors and S = 90 for Z sensor (f:;; 900 MHz in
         TEM-cell; f > 1800 MHz: R22 waveguide).
    •    NORM(f)x,y ,z = NORMx,y,z * frequency_response (see Frequency Response Chart).

    •    DCPx,y,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW
         signal (no uncertainty required) . DCP does not depend on frequency nor media.
    •    PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal
         characteristics
    •    Ax,y,z; Bx,y ,z; Cx,y,z; Dx,y,z; VRx,y,z: A, B, C, D are numerical linearization parameters assessed based on
         the data of power sweep for specific modulation signal. The parameters do not depend on frequency nor
         media. VR is the maximum calibration range expressed in RMS voltage across the diode.
    •    Spherical isotropy (30 deviation from isotropy): in a locally homogeneous field realized using an open
         waveguide setup.
    •    Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip
         (on probe axis). No tolerance required.
    •    Connector Angle: The angle is assessed using the information gained by determining the NORMx (no
         uncertainty required) .

Connector angle              information used in DASY system to align probe sensor X to the robot
                             coordinate system.

Methods Applied and Interpretation of Parameters
  •   DC Voltage Measurement: Calibration Factor assessed for use in DASY system by
     comparison with a calibrated instrument traceable to national standards. The figure given
     corresponds to the full scale range of the voltmeter in the respective range.
     •    Connector angle: The angle of the connector is assessed measuring the angle
          mechanically by a tool inserted. Uncertainty is not required.
     •    The following parameters as documented in the Appendix contain technical information as a
          result from the performance test and require no uncertainty.
         •     DC Voltage Measurement Linearity: Verification of the Linearity at +10% and -10% of
               the nominal calibration voltage. Influence of offset voltage is included in this
               measurement.
         •     Common mode sensitivity: Influence of a positive or negative common mode voltage on
               the differential measurement.
         •     Channel separation: Influence of a voltage on the neighbor channels not subject to an
               input voltage.
         •     AD Converter Values with inputs shorted: Values on the internal AD converte r
               corresponding to zero input voltage
         •     Input Offset Measurement Output voltage and statistical results over a large number of
               zero voltage measurements.
         •     Input Offset Current: Typical value for information; Maximum channel input offset
               current, not considering the input resistance.
         •     Input resistance: Typical value for information: DAE input resistance at the connector,
               during internal auto-zeroing and during measurement.
         •     Low Battery Alarm Voltage: Typical value for information. Below this voltage, a battery
               alarm signal is generated.
         •     Power consumption: Typical value for information. Supply currents in various operating
               modes.
