Calibration Laboratory of S Schweizerischer Kalibrierdienst Schmid & Partner C Service suisse d‘étalonnage Engineering AG 5 Servizio svizzero di taratura Zeughausstrasse 43, 8004 Zurich, Switzerland Swiss Calibration Service Accredited by the Swiss Accreditation Service (SAS) Accreditation No.: SCS 0108 The Swiss Accreditation Service is one of the signatories to the EA Multilateral Agreement for the recognition of calibration certificates Glossary: NORMx,y,z sensitivity in free space DCP diode compression point CF crest factor (1/duty_cycle) of the RF signal A, B, C, D modulation dependent linearization parameters En incident E—field orientation normal to probe axis Ep incident E—field orientation paralle! to probe axis Polarization q @ rotation around probe axis Polarization 8 8 rotation around an axis that is in the plane normal to probe axis (at measurement center), iie., 8 = 0 is normal to probe axis 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 8 = 0 for XY sensors and 8 = 90 for Z sensor (f < 900 MHz in TEM—cell; f > 1800 MHz: R22 waveguide). NORM(P)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 (3D 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). Certificate No: EF3—4041_Mar19 Page 2 of 9
