1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a portable transmitter for a Remote control car operating at 27.145 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 Antenna Gain: 0dBi The nominal conducted output power specified: -29.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -31.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: The w orst-case peak radiated emission for the EUT is 65.7d BμV/m at 3m in the frequency 27.145MHz The EIRP = [(FS*D) ^2 / 30] mW= -29.53dBm The ERP = EIRP – 2.15 = -31.68 dBm which is within the production variation. The maximun conducted output power specified is -26dBm =0 .0025mW The source- based time-averaging conducted output power = 0.0025* Duty Cycle mW < 0.1 mW (Duty Cycle<100%) The S AR 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 = 26.9565ms Effective period of the cycle = 782.6μs x 10 + 2.2609ms x 4 = 16.8696ms DC = 16.8696ms / 26.9565ms = 0.6258 or 62.58% FCC ID: 2AASIYD2289827
