FCC RF Test Report Report No. : FG8D1803-01B 3.4 Radiated Spurious Emission 3.4.1 Description of Radiated Spurious Emission The radiated spurious emission was measured by substitution method according to ANSI C63.26. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitter power (P) by a factor of at least 43 + 10 log (P) dB. For Band 7 The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitter power (P) by a factor of at least 55 + 10 log (P) dB. The spectrum is scanned from 30 MHz up to a frequency including its 10th harmonic. 3.4.2 Test Procedures 1. The testing follows ANSI C63.26 Section 5.5 2. The EUT was placed on a turntable with 0.8 meter height for frequency below 1GHz and 1.5 meter height for frequency above 1GHz respectively above ground. 3. The EUT was set 3 meters from the receiving antenna mounted on the antenna tower. 4. The table was rotated 360 degrees to determine the position of the highest spurious emission. 5. The height of the receiving antenna is varied between 1m to 4m to search the maximum spurious emission for both horizontal and vertical polarizations. 6. During the measurement, the system simulator parameters were set to force the EUT transmitting at maximum output power. 7. Make the measurement with the spectrum analyzer's RBW = 1MHz, VBW = 3MHz, taking the record of maximum spurious emission. 8. A horn antenna was substituted in place of the EUT and was driven by a signal generator. 9. Tune the output power of signal generator to the same emission level with EUT maximum spurious emission. 10. EIRP (dBm) = S.G. Power – Tx Cable Loss + Tx Antenna Gain 11. ERP (dBm) = EIRP - 2.15 12. The RF fundamental frequency should be excluded against the limit line in the operating frequency band. The limit line is derived from 43 + 10log(P)dB below the transmitter power P(Watts) = P(W)- [43 + 10log(P)] (dB) = [30 + 10log(P)] (dBm) - [43 + 10log(P)] (dB) = -13dBm. 13. For Band 7, 38: The limit line is derived from 55 + 10log(P)dB below the transmitter power P(Watts) Sporton International (Kunshan) Inc.
