INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a transmitter for a Toy RC Monster Spinning Car Turbo Tumbler operating at 27.145 MHz which is controlled by a crystal. The EUT is powered by one 9.0V 6LR61 battery. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Antenna Gain: 0dBi The nominal conducted output power specified: -35.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -37.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: The worst-case peak radiated emission for the EUT is 59.0dBuV/m at 3m in the frequency 27.145MHz The EIRP = [(FS*D) ^2 / 30] mW= -36.23dBm The ERP = EIRP – 2.15 = -38.38 dBm which is within the production variation. The maximun conducted output power specified is -32dBm =0.0006mW The source- based time-averaging conducted output power = 0.0006* Duty Cycle mW < 0.0006mW (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 = 20.4348ms Effective period of the cycle = 1.6522ms x 4 + 521.7µs x 10 =11.8258ms DC =11.8258ms / 20.4348ms =0.5787 or 57.87% FCC ID: Z6QFC12027D 1
