6    Radio Spectrum Technical Requirement
6.1 Antenna Requirement
6.1.1 Test Requirement:
      47 CFR Part 15, Subpart C 15.203
      Limit:



6.1.2 Conclusion
      Standard Requirement:
      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. The use of a antenna that uses a unique coupling to
      the intentional radiator, the manufacturer may design the unit permanently attached antenna or of an
      so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or
      electrical connector is prohibited.

      EUT Antenna:
      The antenna is integrated on the main PCB and no consideration of replacement. The best case gain
      of the antenna is 0dBi.

      Antenna location: Refer to Appendix(Internal photos)

7.3 Radiated Emissions (9kHz-30MHz)

Remark: The emission limits shown in the above table are based on measurements employing a
CISPR quasi-peak detector except for the frequency bands 9-90kHz, 110-490kHz. Radiated
emission limits in these three bands are based on measurements employing an average detector,
the peak field strength of any emission shall not exceed the maximum permitted average limits
specified above by more than 20 dB under any condition of modulation.

If field strength is measured at only a single point, then that point shall be at the radial from the EUT that
produces the maximum emission at the frequency being measured, as described in 5.4. If that point is closer
to the EUT than λ/2π and the limit distance is greater than λ/2π, the measurement shall be extrapolated to
the limit distance by conservatively presuming that the field strength decreases at a 40 dB/decade of distance
rate to the λ/2π distance, and at a 20 dB/decade of distance rate beyond λ/2π. This shall be accomplished
using Equation (2):

                         FS(10m) = FS(30/300m) + 40log{d(near field)/d(10m)} + 20log{d(30/300m)/d(near field)}     (2)

If the single point measured is at a distance greater than λ/2π, then extrapolation to the limit distance shall be
calculated using Equation (3):

                         FS(10m) = FS(30/300m) + 20log{d(30/300m)/d(10m)}                                    (3)

If both the single point and the limit distance are equal to or closer to the EUT than λ/2π, then extrapolation to
the limit distance shall be calculated using Equation (4):

                         FS(10m) = FS(30/300m) + 40log{d(30/300m)/d(10m)}                                    (4)

Remark:
                       dnear field = 47.77 / fMHz
where fMHz is the frequency of the emission being measured in MHz.

7.3.3 Measurement Procedure and Data
      For testing performed with the loop antenna, the center of the loop was positioned 1 m above the
      ground and positioned with its plane vertical at the specified distance from the EUT. During testing
      the loop was rotated about its vertical axis for maximum response at each azimuth and also
      investigated with the loop positioned in the horizontal plane. Only the worst position of vertical was
      shown in the report.

Remark: The emission limits shown in the above table are based on measurements employing a CISPR
quasi-peak detector except for the frequency bands above 1000 MHz. Radiated emission limits in these
three bands are based on measurements employing an average detector, the peak field strength of any
emission shall not exceed the maximum permitted average limits specified above by more than 20 dB under
any condition of modulation.

7.4.3 Measurement Procedure and Data
      a. The EUT was placed on the top of a rotating table 0.8 meters above the ground for below 1GHz at
      a 3 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position of
      the highest radiation.
      b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on
      the top of a variable-height antenna tower.
      c. The antenna height is varied from one meter to four meters above the ground to determine the
      maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set
      to make the measurement.
      d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was
      tuned to heights from 1 meter to 4 meters (for the test frequency of below 30MHz, the antenna was
      tuned to heights 1 meter) and the rotatable table was turned from 0 degrees to 360 degrees to find
      the maximum reading.
      e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum
      Hold Mode.
      f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing
      could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that
      did not have 10dB margin would be re-tested one by one using peak, quasi-peak or average method
      as specified and then reported in a data sheet.
      g. Test the EUT in the lowest channel,the middle channel,the Highest channel
      h. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode,And
      found the X axis positioning which it is worse case.
      i. Repeat above procedures until all frequencies measured was complete.
