 4. Antenna Requirements

   4.1. Standard Applicable
         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.

         And according to FCC 47 CFR Section 15.249, if transmitting antennas of directional gain greater
         than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of
         the antenna exceeds 6dBi.

 5. Test of AC Power Line Conducted Emission

   5.1. Test Limit

         Conducted Emissions were measured from 150 kHz to 30 MHz with a bandwidth of 9 KHz,
         according to the methods defined in ANSI C63.4-2014. The EUT was placed on a nonmetallic
         stand in a shielded room 0.8 meters above the ground plane. The interface cables and
         equipment positioning were varied within limits of reasonable applications to determine the
         position produced maximum conducted emissions.

         *Decreases with the logarithm of the frequency.




   5.2. Test Procedures

         a. The EUT was placed 0.4 meter from the conducting wall of the shielding room was kept at
              least 80 centimeters from any other grounded conducting surface.
         b. Connect EUT to the power mains through a line impedance stabilization network (LISN).
         c. All the support units are connecting to the other LISN.
         d. The LISN provides 50 ohm coupling impedance for the measuring instrument.
         e. The FCC states that a 50 ohm, 50 micro-Henry LISN should be used.
         f.   Both sides of AC line were checked for maximum conducted interference.
         g. The frequency range from 150 kHz to 30 MHz was searched.
         h. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with
              Maximum Hold Mode.

   6.2. Test Procedures
         a. The EUT was placed on a rotatable table top 0.8 meter above ground.
         b. The EUT was set 3 meters from the interference receiving antenna which was mounted on
               the top of a variable height antenna tower.
         c. The table was rotated 360 degrees to determine the position of the highest radiation.
         d. The antenna is a broadband antenna and its height is varied between one meter and four
               meters above ground to find the maximum value of the field strength both horizontal
               polarization and vertical polarization of the antenna are set to make the measurement.
         e. For each suspected emission the EUT was arranged to its worst case and then tune the
               antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the
               maximum reading.
         f.    Set the test-receiver system to Peak or CISPR quasi-peak Detect Function and specified
               bandwidth with Maximum Hold Mode.
         g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then
               testing will be stopped and peak values of EUT will be reported, otherwise, the emissions
               which do not have 3 dB margin will be repeated one by one using the quasi-peak method and
               reported.
         h. “Cone of radiation” has been considered to be 3dB beamwidth of the measurement antenna.


       NOTE:
       1. The resolution bandwidth of test receiver/spectrum analyzer is 300Hz or CISPS 200Hz(QP
              detector) at frequency Below 150 kHz.
       2. The resolution bandwidth of test receiver/spectrum analyzer is 10KHz or CISPS 9KHz(QP
              detector) at frequency 150 kHz to 30 MHz.
       3. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
              Peak detection (PK) and Quasi-peak detection (QP) at frequency below 1GHz.

 7. Frequency Stability
   7.1. Test Procedure

       1. The EUT was placed inside the Temperature and Humidity chamber.
       2. The transmitter output was connected to spectrum analyzer.
       3. Turn the EUT on and couple its output to a spectrum analyzer.
       4. Turn the EUT off and set the chamber to the highest temperature specified.
       5. Allow sufficient time (approximately 30 min) for the temperature of the chamber to stabilize,
          turn the EUT on and measure the operating frequency after 2, 5, and 10 minutes.
       6. Repeat step 2 and 3 with the temperature chamber set to the lowest temperature.
       7. The test chamber was allowed to stabilize at +20 degree C for a minimum of 30 minutes. The
          supply voltage was then adjusted on the EUT from 85% to 115% and the frequency record.
