The spurious emissions from the antenna terminal were measured. The transmitter output power was attenuated using an attenuator and the frequency spectrum investigated from 3KHz to 20GHz. The resolution bandwidth of 1MHz was employed for frequency band 3KHz to 20GHz. The spectrum analyzer detector was set to RMS. For MIMO mode configurations, the limit was adjusted with a correction of -6.02dB [10Log4] by using the Measure and Add 10Log(N) dB technique according to FCC KDB 662911 D01 Multiple Transmitter Output accounting for simultaneous transmission from antenna ports RF A,B,C and D. Then the limit was adjust to -19.02dBm. A.4.3 Measurement limit The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10log(P) dB. ©Copyright.

No. I19Z61663-WMD01 Page 53 of 60 A.5 Radiated Spurious Emission A.5.1 Reference FCC CFR 47 Part 2, Clause 2.1053 FCC CFR 47 Part 27, Clause 27.53 (m) A.5.2 Method of measurement The measurements procedures in TIA-603-E: 2016 are used. This measurement is carried out in semi-anechoic chamber. A preliminary profile of the Spurious Radiated Emissions was obtained by operating the EUT on a remotely controlled turntable within the chamber. Measurements of emissions from the EUT were obtained with the measurement antenna in both horizontal and vertical polarisations. Emissions identified within the range 30MHz to 30GHz were then formally measured using a peak detector as the worst case. The limits for outside a licensee’s frequency band(s) of operation the power of the spurious emissions have been calculated, as shown below using the following formula: Field Strength of Carrier - (43 + 10Log (P)) dB Where: Field Strength is measured in dBμV/m P is measured Transmitter Power in Watts The EUT was measured with the antenna height varied between 1 and 4 m with the turntable rotated between 0 and 360 degrees. The emission of any outside a licensee’s frequencies within 20dB of the limit were measured with the substitution method used according to the standard. The measurements were performed at a 3m distance unless otherwise stated. A.5.3 Measurement limit The field strength of the carrier has been calculated assuming that the power is to be fed to a half-wave tuned dipoles as per 2.1053 (a). E(v/m)=(30 x Gi x Po )0.5 / d Where Gi is the antenna gain of ideal half-wave dipoles, Po is the power out of the transceiver in W, d is the measurement distance in meter. Therefore at 3m measurement distance the field strength using the lowest transceiver output power would be: E(v/m)=(30 x 1.64 x 16.56)0.5 / 3 = 9.51V/m = 139.57 dBμV/m As per 24.238 (a) the spurious emission must be attenuated by 43 + 10log (Po) dB this gives: 43 + 10log(16.56) = 55.19 dB Therefore the limit at 3m measurement distance is: 139.57 – 55.19 = 84.4 dBμV/m These limits have been used to determine Pass or Fail for the harmonics measured and detailed in the following results. ©Copyright.
