Radiated Emissions Radiated Test Conditions for Radiated Spurious and Band-Edge Emissions (Restricted Bands) FCC CFR 47 Part 15 Subpart C Standard: 15.247 (DTS) & Ambient Temp. (ºC): 20.0 - 24.5 RSS GEN Test Heading: Radiated Spurious Rel. Humidity (%): 32 - 45 Standard Section(s): 15.205, 15.209 & 8.9 Pressure (mBars): 999 - 1001 Reference Document(s): See Normative References Test Procedure for Radiated Spurious and Band-Edge Emissions (Restricted Bands) Radiated emissions for restricted bands above 1 GHz are measured in the anechoic chamber at a 3-meter distance on every azimuth in both horizontal and vertical polarities. The emissions are recorded and maximized as a function of azimuth by rotation through 360° with a spectrum analyzer in peak hold mode. Depending on the frequency band spanned a notch filter and waveguide filter was used to remove the fundamental frequency. The highest emissions relative to the limit are listed for each frequency spanned. Measurements on any restricted band frequency or frequencies above 1 GHz are based on the use of measurement instrumentation employing peak and average detectors. All measurements were performed using a resolution bandwidth of 1 MHz. Test configuration and setup for Radiated Spurious and Band-Edge Measurement were per the Radiated Test Set-up specified in this document. Limits for Restricted Bands Peak emission: 74 dBuV/m Average emission: 54 dBuV/m Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Loss, and subtracting Amplifier Gain from the measured reading. All factors are included in the reported data. FS = R + AF + CORR - FO where: FS = Field Strength R = Measured Spectrum analyzer Input Amplitude AF = Antenna Factor CORR = Correction Factor = CL – AG + NFL CL = Cable Loss AG = Amplifier Gain FO = Distance Falloff Factor NFL = Notch Filter Loss or Waveguide Loss Example: Given receiver input reading of 51.5 dBmV; Antenna Factor of 8.5 dB; Cable Loss of 1.3 dB; Falloff Factor of 0 dB, an Amplifier Gain of 26 dB and Notch Filter Loss of 1 dB. The Field Strength (FS) of the measured emission is: FS = 51.5 + 8.5 + 1.3 - 26.0 +1 = 36.3 dBmV/m Conversion between dBmV/m (or dBmV) and mV/m (or mV) are as follows: Level (dBmV/m) = 20 * Log (level (mV/m)) 40 dBmV/m = 100 mV/m 48 dBmV/m = 250 mV/m Restricted Bands of Operation (15.205) This test report may be reproduced in full only.

Title: Silver Spring Networks Milli™5 To: FCC 15.247 & RSS 247 (DTS) Serial #: SSNT122-U2_Radiated Rev A Issue Date: 13th October 2016 Page: 13 of 15 2.1.2. Digital Emissions (0.03 - 1 GHz) FCC, Part 15 Subpart C §15.205/ §15.209 Industry Canada ICES-003 §6.2 Test Procedure Testing 30M-1 GHz was performed in a 3-meter anechoic chamber using a CISPR compliant receiver. Preliminary radiated emissions were measured on every azimuth and with the receiving antenna in both horizontal and vertical polarizations. To further maximize emissions the receive antenna was varied between 1 and 4 meters. The emissions are recorded with receiver in peak hold mode. Emissions closest to the limits are measured in the quasi-peak mode with the tuned receiver using a bandwidth of 120 kHz. Only the highest emissions relative to the limit are listed. The anechoic chamber test set-up is identified in Section 6 Test Set-Up Photographs. The EUT had two methods of powering on ac/dc converter and Power over Ethernet (POE). Both modes were tested for emissions below 1GHz. Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Loss, and subtracting Amplifier Gain from the measured reading. In this test facility, the Antenna Factor, Cable Loss, and Amplifier Gains are loaded into the Rohde & Schwarz Receiver and the corrected field strength can be read directly on the receiver. FS = R + AF + CORR where: FS = Field Strength R = Measured Receiver Input Amplitude AF = Antenna Factor CORR = Correction Factor = CL – AG + NFL CL = Cable Loss AG = Amplifier Gain For example: Given a Receiver input reading of 51.5dBV; Antenna Factor of 8.5dB; Cable Loss of 1.3dB; Falloff Factor of 0dB, an Amplifier Gain of 26dB and Notch Filter Loss of 1dB. The Field Strength of the measured emission is: FS = 51.5 + 8.5 + 1.3 - 26.0 +1 = 36.3dBV/m Conversion between dBV/m (or dBV) and V/m (or V) are done as: Level (dBV/m) = 20 * Log (level (V/m)) 40 dBV/m = 100V/m 48 dBV/m = 250V/m This test report may be reproduced in full only.
