                               Analysis Report

The equipment under test (EUT) is a portable transmitter for a RC MINI
MONSTER 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: -18.0dBm (+/- 3dB)
The nominal radiated output power (e.r.p) specified: -20.15dBm (+/- 3dB)
Modulation Type: Pulse modulation

According to the KDB 447498:

     The worst-case peak radiated emission for the EUT is 77.5dBµV/m at 3m
     in the frequency 27.145MHz
     The EIRP = [(FS*D) ^2 / 30] mW= -17.73dBm
     The ERP = EIRP – 2.15 = -19.88 dBm
      which is within the production variation.

     The maximun conducted output power specified is -15dBm =0.03mW
     The source- based time-averaging conducted output power
     = 0.03* Duty Cycle mW < 0.03mW (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 = 18.32ms
Effective period of the cycle = 560.0µs x 10 + 1.520ms x 4 = 11.68ms
DC =11.68ms / 18.32ms = 0.6376 or 63.76%
