Calibration Laboratory of Schweizerischer Kalibrierdienst Schmid & Partner Service suisse d‘étalonnage Engineering AG Servizio svizzero di taratura Zeughausstrasse 43, 8004 Zurich, Switzerland Swiss Calibration Service Accredited by the Swiss Accreditation Service (SAS) Accreditation No.: SCS 108 The Swiss Accreditation Service is one of the signatories to the EA Multilateral Agreement for the recognition of calibration certificates Reference # ANSI—C63.19—2011 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 DASYS5 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 ERS3D—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 3D maxima are available near the end of the dipole arms. Assuming the dipole arms are perfectly in one linge, 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%.

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. Certificate No: CD835V3—1175_May14 Page 3 of 5
