REPORT NO: 12805347-E1V1 DATE: APRIL 25, 2019 FCC ID: C3K1843 ISED: 3048A-1843 §15.249 (a) Except as provided in paragraph (b) of this section, the field strength of emissions from intentional radiators operated within these frequency bands shall comply with the following: Fundamental frequency Field strength of fundamental (millivolts/meter) Field strength of harmonics (microvolts/meter) 902-928 MHz 50 500 2400-2483.5 MHz 50 500 5725-5875 MHz 50 500 24.0-24.25 GHz 250 2500 §15.249 ( d ) Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in §15.209, whichever is the lesser attenuation. (e) As shown in § 15.35(b), for frequencies above 1000 MHz, the field strength limits in paragraphs (a) and (b) of this section are based on average limits. However, the peak field strength of any emission shall not exceed the maximum permitted average limits specified above by more than 20 dB under any condition of modulation. RSS-GEN Clause 6.13.2 (b) (b) If the equipment operates at or above 10 GHz and below 30 GHz: to the fifth harmonic of the highest fundamental frequency or to 100 GHz, whichever is lower. RSS-310 Clause 3.10 Band 24-24.25 GHz Emissions radiated outside the specified frequency band shall be attenuated by at least 50 dB below the level of the fundamental or to the general field strength limits listed in RSS-Gen, whichever is the less stringent. The peak field strength of any emission shall not exceed the maximum permitted average limit specified above by more than 20 dB under any condition of modulation.

REPORT NO: 12805347-E1V1 DATE: APRIL 25, 2019 FCC ID: C3K1843 ISED: 3048A-1843 TEST PROCEDURES ANSI C63.10 47 CFR 15.35 ( c ) (c) Unless otherwise specified, e.g., §15.255(b), and 15.256(l)(5), when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. As an alternative (provided the transmitter operates for longer than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field strength shall be determined from the average absolute voltage during a 0.1 second interval during which the field strength is at its maximum value. PROCEDURE FOR 40 TO 100 GHz External harmonic mixers or downconverters with Standard Gain horn antennas are utilized. Page 13 of 21 UL VERIFICATION SERVICES INC.

REPORT NO: 12805347-E1V1 DATE: APRIL 25, 2019 FCC ID: C3K1843 ISED: 3048A-1843 8.2. RESULTS 8.2.1. APPLICABLE LIMIT Fundamental field strength is referenced from the Microsoft report. The field strength of the fundamental is 94.41 dBuV/m at 3 meters, average. An attenuation of 50 dB yields 44.41 dBuV/m at 3 meters. The §15.209 average limit above 960 MHz is 500 uV/m at 3 meters, equivalent to 54 dBuV/m at 3 meters. The field strength of the fundamental is 96.89 dBuV/m at 3 meters, peak. An attenuation of 50 dB yields 46.89 dBuV/m at 3 meters. The §15.209 peak limit above 960 MHz is 5000 uV/m at 3 meters, equivalent to 74 dBuV/m at 3 meters. The §15.209 limits correspond to the lesser attenuation, for both peak and average emissions. Page 14 of 21 UL VERIFICATION SERVICES INC.
