1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a portable transmitter for a Toy RC ATV operating at 49.860 MHz which is controlled by a crystal. The EUT is powered by one 9.0V 6F22 size battery. For more detail information pls. refer to the user manual. Antenna Type: integral antenna with plastic enclosure Antenna Gain: 0dBi The nominal conducted output power specified: -17.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -19.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: T he worst-case peak radiated emission for the EUT is 78.0dBμV/m at 3m in the frequency 49.860MHz The EIRP = [(FS*D) ^2 / 30] mW= -17.23dBm The ERP = EIRP – 2.15 = -19.38 dBm which is within the production variation. The maximun conducted output power specified is -14.0 dBm = 0.04mW The source- based time-averaging conducted output power = 0.04 * Duty Cycle mW < 0.1 mW (Duty Cycle<100%) The 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 = 18.1ms Effective period of the cycle = 550μs x 10 + 1.5ms x 4 = 11.5ms DC = 11.5ms / 18.1ms = 0.6354 or 63.54% FCC ID: 2ABF4SF2014C49
