2 System Test Configuration

     2.1 EUT Configuration

         The EUT configuration for testing is installed on RF field strength measurement to meet the
         Commissions requirement and operating in a manner which intends to maximize its emission
         characteristics in a continuous normal application.


     2.2 EUT Exercise

         The Transmitter was operated in the normal operating mode. The TX frequency was fixed which was
         for the purpose of the measurements.


     2.3 Test Procedure

         2.3.1 Conducted Emissions
                The EUT is a placed on as turn table which is 0.8 m above ground plane. According to the
                requirements in Section 13.1.4.1 of ANSI C63.10-2013 Conducted emissions from the EUT
                measured in the frequency range between 0.15 MHz and 30 MHz using CISPR Quasi-Peak
                and average detector mode.


         2.3.2 Radiated Emissions
                 The EUT is a placed on as turn table which is 0.8 m above ground plane. The turn table shall
                 rotate 360 degrees to determine the position of maximum emission level. EUT is set 3m away
                 from the receiving antenna which varied from 1m to 4m to find out the highest emission. And
                 also, each emission was to be maximized by changing the polarization of receiving antenna
                 both horizontal and vertical. In order to find out the max. emission, the fixed in a particular
                 direction according to the requirements in Section 13.1.4.1 of ANSI C63.10-2013.

5 Radiated Emission Test

5.1   Measurement Procedure

      1. The EUT was placed on a turn table which is 0.8m above ground plane.
      2. Maximum procedure was performed on the six highest emissions to ensure
      EUT compliance.
      3. And also, each emission was to be maximized by changing the polarization of
         receiving antenna both horizontal and vertical.
      4. Repeat above procedures until all frequency measured were complete.

7         Antenna Application

7.1   Antenna requirement

For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator
shall be designed to ensure that no antenna other than that furnished by the responsible
party shall be used with the device.




7.2 Result
The EUT’s antenna, permanent attached antenna, used an Induction coil and integrated
on PCB, The antenna’s gain meets the requirement.
