1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a transmitter for an Off-Road Go! operating at 27.145 MHz which is controlled by a crystal. The EUT is powered by two 1.5V AA battery. For more detail information pls. refer to the user manual. Antenna Type: integral antenna Antenna Gain: 0dBi Modulation Type: Pulse modulation The nominal conducted output power specified: -17.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -19.15dBm (+/- 3dB) According to the KDB 447498: The worst-case peak radiated emission for the EUT is 77.8dBuV/m at 3m in the frequency 27.145MHz The EIRP = [(FS*D) ^2 / 30] mW= -17.43dBm The ERP = EIRP – 2.15 = -19.58dBm which is within the production variation. The maximun conducted output power specified is -14.0dBm = 0.0398mW The source- based time-averaging conducted output power = 0.0398* Duty Cycle mW < 0.0398mW (Duty Cycle<100%) The SAR Exclusion Threshold Level for 27.145MHz when the minimum test separation distance is < 50mm: = 474 * [1 + log(100/f(MHz)]/2 = 371.2 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 = 70.145ms Effective period of the cycle = 1.449ms x 4 + 0.435ms x 63 =33.20ms DC =33.20ms / 70.145ms =0.4733 or 47.33% FCC ID: PKG12099RC27A
