   Calibration method:                     The instrument was allowed to acclimatize for at least 2 hours before any measurements were made.

                                           During calibration, all axis of the field probe are switched on as in the normal isotropic mode of
                                           operation of the probe.

                                           The calibration is performed in a TEM cell. The calculated field method is used for the calibration.

                                                                                   Applied field strength
                                                              Correction Factor = --------------------------------
                                                                                  Measured field strength

                                           The polarization of the E-field is vertical. For each frequency and field strength setting, the field probe
                                           is rotated so that each position is aligned with the E-field. The axis under test is always perpendicular
                                           to the direction of propagation and parallel to the E-field.

                                           The H-Field is calculated by dividing the E-Field with 377 ohm.

                                           The probe position has been determined as follows:
                                           The point of view is from the antenna to the probe.

                                           Position 1: probe horizontal, perpendicular to the field, display horizontal (up). Probe head aligned
                                           with center of the antenna, probe box to the right.

                                           Position 2: probe horizontal, perpendicular to the field, display aligned vertical, to the front facing the
                                           antenna. Probe head aligned with center of the antenna, probe box to the right.

                                           Position 3: probe horizontal, perpendicular to the field, display horizontal (down). Probe head aligned
                                           with center of the antenna, probe box to the right.

                            See page 7 and 8 for a detailed drawing of the probe positioning.

   Ambient conditions:      The calibration was carried out in a screened room, at an ambient temperature of (23 ± 2)°C and a
                            relative humidity of (50 ± 10)%.

   Period of calibration:   2016 February, 9.

   Due date:                2017 February, 9

   Results:                 The results are listed on page 3 to 5.
                            No adjustments have been made to the instrument.
                            The measured values were calculated from a single sample.

                            This certificate replaces certificate number 201600474.00.
                            Frequency range corrected at page 4.

   Uncertainty:             The reported expanded 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 standard uncertainty of measurement has been
                            determined in accordance with EA publication EA-4/02.

                            The uncertainties refer to the measured values only with no account being taken of the ability of the
                            instruments under test to maintain their calibration.

   Traceability:            The measurements have been executed using standards for which the traceability to (inter)national
                            standards has been demonstrated towards the RvA.
