Model: RC4X1WN-A9-CCT/DIM 7. RF Output Power 7.1 Standard Applicable According to 15.247(b)(3). For systems using digital modulation in the 902–928 MHz, 2400–2483.5 MHz, and 5725–5850 MHz bands: 1 Watt. 7.2 Test Procedure According to the KDB-558074 D01 v03r05, 9.2.2.2, when this option is exercised, the measured power is to be referenced to the OBW rather than the DTS bandwidth a) Set span to at least 1.5 times the OBW. b) Set RBW = 1-5% of the OBW, not to exceed 1 MHz. c) Set VBW ≥ 3 x RBW. d) Number of points in sweep ≥ 2 × span / RBW. (This gives bin-to-bin spacing ≤ RBW/2, so that narrowband signals are not lost between frequency bins.) e) Sweep time = auto. f) Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode. g) If transmit duty cycle < 98 %, use a sweep trigger with the level set to enable triggering only on full power pulses. The transmitter shall operate at maximum power control level for the entire duration of every sweep. If the EUT transmits continuously (i.e., with no off intervals) or at duty cycle ≥ 98 %, and if each transmission is entirely at the maximum power control level, then the trigger shall be set to “free run”. h) Trace average at least 100 traces in power averaging (i.e., RMS) mode. i) Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band power measurement function, with band limits set equal to the OBW band edges. If the instrument does not have a band power function, sum the spectrum levels (in power units) at intervals equal to the RBW extending across the entire OBW of the spectrum. 7.3 Environmental Conditions Temperature: 26 C Relative Humidity: 57 ATM Pressure: 1011 mbar 7.4 Summary of Test Results/Plots Frequency Reading Output Power Limit Test Mode MHz dBm mW mW 2405 6.805 4.792 1000 ZigBee 2445 6.755 4.737 1000 2480 7.991 6.297 1000 REPORT NO.: STR16088089I PAGE 16 OF 28 FCC PART 15.247

Model: RC4X1WN-A9-CCT/DIM 8. Field Strength of Spurious Emissions 8.1 Standard Applicable According to §15.247(d), in any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 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 the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a). The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. Spurious Radiated Emissions measurements starting below or at the lowest crystal frequency. 8.2 Test Procedure The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification used was with the FCC Part 15.205 15.247(a) and FCC Part 15.209 Limit. The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. The spacing between the peripherals was 10 cm. REPORT NO.: STR16088089I PAGE 17 OF 28 FCC PART 15.247

Model: RC4X1WN-A9-CCT/DIM 9. Out of Band Emissions 9.1 Standard Applicable According to §15.247 (d) In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 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 the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a). 9.2 Test Procedure According to the KDB 558074D01 v03r04, the band-edge radiated test method as follows: Set span = wide enough to capture the peak level of the emission operating on the channel closest to the bandedge, as well as any modulation products which fall outside of the authorized band of operation (2310MHz to 2420MHz for low bandedge, 2460MHz to 2500MHz for the high bandedge) RBW = 1MHz, VBW = 1MHz for peak value measured RBW = 1MHz, VBW = 10Hz for average value measured Sweep = auto; Detector function = peak/average; Trace = max hold All the trace to stabilize, set the marker on the emission at the bandedge, or on the highest modulation product outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta function, then use the marker-to-peak function to move the marker to the peak of the in-band emission. Those emission must comply with the 15.209 limit for fall in the restricted bands listed in section 15.205. Note that the method of measurement KDB publication number: 913591 may be used for the radiated bandedge measurements. According to the KDB 558074 D01 v03r05, the conducted spurious emissions test method as follows: 1. Set start frequency to DTS channel edge frequency. 2. Set stop frequency so as to encompass the spectrum to be examined. 3. Set RBW = 100 kHz. 4. Set VBW ≥ 300 kHz. 5. Detector = peak. 6. Trace Mode = max hold. 7. Sweep = auto couple. 8. Allow the trace to stabilize (this may take some time, depending on the extent of the span). 9. Use peak marker function to determine maximum amplitude of all unwanted emissions within any 100 kHz bandwidth. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) are attenuated by at least the minimum requirements specified in section 8.1. Report the three highest emissions relative to the limit. REPORT NO.: STR16088089I PAGE 26 OF 28 FCC PART 15.247
