1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a portable transmitter for a 4 CH R/C TANK W/LIGHT operating at 49.86MHz. The EUT is powered by two 1.5V AA size batteries. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna with unique antenna connector Antenna Gain: 0dBi The nominal conducted output power specified: -30.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -32.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: T he worst-case peak radiated emission for the EUT is 65.0dBμV/m at 3m in the frequency 49.86MHz The EIRP = [(FS*D) ^2 / 30] mW= -30.23dBm The ERP = EIRP – 2.15 = -32.38 dBm which is within the production variation. The maximun conducted output power specified is -27dB m =0.002mW The source- based time-averaging conducted output power = 0.002* Duty Cycle mW< 0.1m W (Duty Cycle<100%) T he SAR Exclusion Threshold Level for 49.860MHz when the minimum test separation distance is < 50mm: = 474 * [1 + log(100/f(MHz)]/2 = 308.6 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. Transmitter Duty Cycle Calculation The duration of one cycle = 18.8696ms Effective period of the cycle = 521.7μs x 10 + 1.4783ms x 4 = 11.1302 ms DC = 11.1302 ms / 18.8696ms = 0.5898 or 58.98% FCC ID: 2AECZKS10401000049
