Report Number: TRA-034693-47-03B 11 Radiated emissions 11.1 Definitions Out-of-band emissions Emissions on a frequency or frequencies immediately outside the necessary bandwidth which result from the modulation process, but exclude spurious emissions. Spurious emissions Emissions on a frequency or frequencies which 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 A frequency band in which intentional radiators are permitted to radiate only spurious emissions but not fundamental signals. 11.2 Test Parameters Test Location: Element Skelmersdale Test Chamber: Chamber 3 Test Standard and Clause: ANSI C63.10-2013, Clause 6.5 and 6.6 EUT Frequencies Measured: 433.050 MHz / 434.790 MHz EUT Channel Bandwidths: 33 kHz Deviations From Standard: None Measurement BW: 30 MHz to 1 GHz: 120 kHz Above 1 GHz: 1 MHz Measurement Detector: Up to 1 GHz: quasi-peak Above 1 GHz: RMS average and Peak Environmental Conditions (Normal Environment) Temperature: 22 °C +15 ºC to +35 ºC (as declared) Humidity: 43 % RH 20 % RH to 75 % RH (as declared) Supply: 6 V dc 6 V dc (as declared) Page 15 of 33

Report Number: TRA-034693-47-03B 11.3 Test Limit In addition to the provisions of § 15.205, the field strength of emissions from intentional radiators operated under this section shall not exceed the following:. Fundamental Field Strength Of Field Strength Of Spurious Frequency Fundamental Emissions (MHz) (μV/m) (μV/m) 40.66-40.70 2,250 225 70-130 1,250 125 130-174 1,250 to 3,7501 125 to 3751 174-260 3,750 375 260-470 3,750 to 12,5001 375 to 1,2501 Above 470 12,500 1,250 1 Linear Interpretations The above field strength limits are specified at a distance of 3 meters. The tighter limits apply at the band edges. Intentional radiators operating under the provisions of this section shall demonstrate compliance with the limits on the field strength of emissions, as shown in the above table, based on the average value of the measured emissions. As an alternative, compliance with the limits in the above table may be based on the use of measurement instrumentation with a CISPR quasi-peak detector. The specific method of measurement employed shall be specified in the application for equipment authorization. If average emission measurements are employed, the provisions in § 15.35 for averaging pulsed emissions and for limiting peak emissions apply. Further, compliance with the provisions of § 15.205 shall be demonstrated using the measurement instrumentation specified in that section. The limits on the field strength of the spurious emissions in the above table are based on the fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated to the average (or, alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown in § 15.209, whichever limit permits a higher field strength. General Field Strength Limits for License-Exempt Transmitters at Frequencies above 30 MHz Frequency Field Strength (MHz) (μV/m at 3 m) 30 to 88 100 88 to 216 150 216 to 960 200 Above 960 500 n.b. per FCC 47CFR15.35(b) peak limit is 20 dB above average.

Report Number: TRA-034693-47-03B 11.4 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 100 kHz RBW. If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in ANSI C63.10 are followed. Alternatively, a layout closest to normal use (as declared by the provider) is employed, (see EUT setup photographs for more detail). Emissions between 30 MHz and 1 GHz are measured using calibrated broadband antennas. Emissions above 1 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 360 degrees in azimuth until the highest emission is detected. At the previously determined azimuth the test antenna is raised and lowered from 1 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 + AF – PA + DC – CF Where, PR is the power recorded on the receiver / spectrum analyzer in dBμV; CL is the cable loss in dB; AF is the test antenna factor in dB/m; PA 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.

Report Number: TRA-034693-47-03B 12 Occupied Bandwidth 12.1 Definitions Occupied bandwidth The width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers emitted are each equal to 0.5 % of the emitted power. This is also known as the 99 % emission bandwidth. For transmitters in which there are multiple carriers, contiguous or non-contiguous in frequency, the occupied bandwidth is to be the sum of the occupied bandwidths of the individual carriers. 20 dB bandwidth The emission bandwidth (x dB) is defined as the frequency range between two points, one above and one below the carrier frequency, at which the spectral density of the emission is attenuated x dB below the maximum in-band spectral density of the modulated signal. 12.2 Test Parameters Test Location: Element Skelmersdale Test Chamber: Radio Laboratory Test Standard and Clause: ANSI C63.10-2013, Clause 6.9 EUT Frequencies Measured: 433.050 MHz / 434.790 MHz EUT Channel Bandwidths: 33 kHz EUT Test Modulations: 2-FSK Deviations From Standard: None Measurement BW: 500 Hz (requirement: 1 % to 5 % OBW) Spectrum Analyzer Video BW: 3 kHz (requirement at least 3x RBW) Measurement Span: 75 kHz (requirement 2 to 5 times OBW) Measurement Detector: Peak Environmental Conditions (Normal Environment) Temperature: 22 °C +15 ºC to +35 ºC (as declared) Humidity: 43 % RH 20 % RH to 75 % RH (as declared) Supply: 6 V dc 6 V dc (as declared) Page 20 of 33

Report Number: TRA-034693-47-03B 12.3 Test Limit Federal Communications Commission: Intentional radiators operating under the alternative provisions to the general emission limits, as contained in §§ 15.217 through 15.257 and in subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. The bandwidth of the emission shall be no wider than 0.25% of the center frequency for devices operating above 70 MHz and below 900 MHz. For devices operating above 900 MHz, the emission shall be no wider than 0.5% of the center frequency. Bandwidth is determined at the points 20 dB down from the modulated carrier. 12.4 Test Method With the EUT setup as per section 9 of this report and connected as per Figure iii, the bandwidth of the EUT was measured on a spectrum analyser. The measurements were performed with EUT set at its maximum duty. All modulation schemes, data rates and power settings were used to observe the worst-case configuration in each bandwidth.

Report Number: TRA-034693-47-03B 14.4 Test Method With the EUT setup as per section 9 of this report and connected as per Figure vii, the duty of the EUT was calculated from the sum of total on and off times over the observation period. The measurements were performed with EUT set at its maximum duty. All modulation schemes, bandwidths, data rates and power settings were used to observe the worst-case configuration. [1] Single antenna output devices Duty was measured at the antenna port / at a distance of 3 m. [2] Multiple antenna output devices Duty was measured as the combination of all ports simultaneously / at a distance of 3 m. The duty cycle correction factor, DC, is used to adjust peak emissions (voltage) to give an average value and is calculated by: DC = 20 log (duty ratio) Where, duty ratio is total on-time divided by total off-time in the worst-case pulse train or 100 ms, whichever is longer.
