24 Report Number: TR B 4 Out-of-band and spurious emissions 4. Definition Out-of-band emission. Emission on a frequency or frequencies immediately outside the necessary bandwidth that results from the modulation process but excluding spurious emissions. Spurious emission. Emission on a frequency or frequencies that are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information. Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products, and frequency conversion products, but exclude out-of-band emissions. Restricted bands frequency band in which intentional radiators are permitted to radiate only spurious emissions but not fundamental signals. 4.2 Test Parameters Test Location: Test Chamber: Element Hull REF886 Test Standard and Clause: NSI C63.-3, Clause 6.5 and 6.6 EUT Channels / Frequencies Measured: EUT Channel Bandwidths: Deviations From Standard: Measurement BW: Measurement Detector: 22 MHz / 24 MHz / 248 MHz 2 MHz None MHz to GHz: khz bove GHz: MHz Up to GHz: quasi-peak bove GHz: RMS average and Peak Environmental Conditions (Normal Environment) Temperature: 22 C Humidity: 32 % RH Supply:.25 Vdc +5 ºC to +35 ºC (as declared) % RH to 75 % RH (as declared) New Battery RF95 3.

25 Report Number: TR B 4.3 Test Limit In any khz bandwidth outside the frequency band in which the spread spectrum or digitally modulated device is operating, the RF power that is produced shall be at least db below that in the khz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided that the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of root-mean-square averaging over a time interval, the attenuation required shall be db instead of db. ttenuation below the general field strength limits specified in FCC 47CFR5.9(a) / RSS- Gen is not required. In addition, radiated emissions which fall in the restricted bands, as defined in FCC 47CFR5.5(a)/RSS-Gen, must also comply with the radiated emission limits specified in FCC 47CFR5.9(a)/RSS-Gen. General Field Strength Limits for License-Exempt Transmitters at Frequencies above MHz Frequency (MHz) Field Strength (μv/m at 3 m) to to to 9 bove Test Method With the EUT setup as per section 9 of this report and connected as per Figure i, the emissions from the EUT were measured on a spectrum analyzer / EMI receiver. Radiated electromagnetic emissions from the EUT are checked first by preview scans. Preview scans for all spectrum and modulation characteristics are checked, using a peak detector and where applicable worst-case determined for function, operation, orientation, etc. for both vertical and horizontal polarisations. Pre-scan plots are shown with a peak detector and khz RBW. If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in NSI C63. are followed. lternatively, a layout closest to normal use (as declared by the provider) is employed, (see EUT setup photographs for more detail). Emissions between MHz and GHz are measured using calibrated broadband antennas. Emissions above GHz are characterized using standard gain horn antennas. Pre-amplifiers and filters are used where required. Care is taken to ensure that test receiver resolution bandwidth, video bandwidth and detector type(s) meet the regulatory requirements. For both horizontal and vertical polarizations, the EUT is then rotated through 3 degrees in azimuth until the highest emission is detected. t the previously determined azimuth the test antenna is raised and lowered from to 4 m in height until a maximum emission level is detected, this maximum value is recorded. Power values measured on the test receiver / analyzer are converted to field strength, FS, in dbμv/m at the regulatory distance, using: FS = PR + CL + F P + DC CF RF95 3. Page 25 of 43

26 Report Number: TR B Where, PR is the power recorded on the receiver / spectrum analyzer in dbμv; CL is the cable loss in db; F is the test antenna factor in db/m; P is the pre-amplifier gain in db (where used); DC is the duty correction factor in db (where used, e.g. harmonics of pulsed fundamental); CF is the distance factor in db (where measurement distance different to limit distance); This field strength value is then compared with the regulatory limit.

The SR Test Exclusion Threshold for operation in the MHz band will be determined as follows SR Exclusion Threshold (SRET) SR Exclusion Threshold = Step + Step 2 Step NT = [ (MP/TSD) * fghz ] NT = Numeric Threshold (3. for -g SR and 7.5 for -g SR) MP = Max Power of channel (mw) (inc tune up) TSD = Min Test separation Distance or mm (whichever is lower) = 5mm (in this case) We can transpose this formula to allow us to find the maximum power of a channel allowed and compare this to the measured maximum power. = [(NT x TSD) / fghz] For Distances Greater than mm Step 2 applies Step 2 (TSDB mm) * } Where: TSDB = Min Test separation Distance (mm) = Note: Step 2 is not required here as the TSD is 5mm.

42 Report Number: TR B Channel Frequency (MHz) EIRP (mw) SR Exclusion Threshold (mw) SR Evaluation Not Required Not Required Not Required Therefore standalone SR evaluation for general population exposure conditions by measurement or numerical simulation is not required. MPE Calculation Prediction of MPE limit at a given distance For purposes of these requirements mobile devices are defined by the FCC as transmitters designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least centimeters is normally maintained between radiating structures and the body of the user or nearby persons. These devices are normally evaluated for exposure potential with relation to the MPE limits. s the cm separation specified under FCC rules may not be achievable under normal operation of the EUT, an RF exposure calculation is needed to show the minimum distance required to be less than the power density limit, as required under FCC rules. Equation from IEEE C95. Where: EIRP EIRP S = re - arranged R = 2 4πR S4π S = power density R = distance to the centre of radiation of the antenna EIRP = EUT Maximum power Result Prediction Frequency (MHz) Maximum EIRP (mw) Power density limit (S) (mw/cm 2 ) Distance (R) cm required to be less than the power density limit Note: EIRP is calculated from maximum radiated field strength.
