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

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




6.1.2 Conclusion
      Standard Requirement:
      An intentional radiator shall be designed to ensure that no antenna other than that furnished by the

7.1.3 Measurement Procedure and Data
      1) The mains terminal disturbance voltage test was conducted in a shielded room.
      2) The EUT was connected to AC power source through a LISN 1 (Line Impedance Stabilization
      Network) which provides a 50ohm/50µH + 5ohm linear impedance. The power cables of all other
      units of the EUT were connected to a second LISN 2, which was bonded to the ground reference
      plane in the same way as the LISN 1 for the unit being measured. A multiple socket outlet strip was
      used to connect multiple power cables to a single LISN provided the rating of the LISN was not
      exceeded.
      3) The tabletop EUT was placed upon a non-metallic table 0.8m above the ground reference plane.
      And for floor-standing arrangement, the EUT was placed on the horizontal ground reference plane,
      4) The test was performed with a vertical ground reference plane. The rear of the EUT shall be 0.4 m
      from the vertical ground reference plane. The vertical ground reference plane was bonded to the
      horizontal ground reference plane. The LISN 1 was placed 0.8 m from the boundary of the unit under
      test and bonded to a ground reference plane for LISNs mounted on top of the ground reference
      plane. This distance was between the closest points of the LISN 1 and the EUT. All other units of the
      EUT and associated equipment was at least 0.8 m from the LISN 2.
      5) In order to find the maximum emission, the relative positions of equipment and all of the interface
      cables must be changed according to ANSI C63.10 on conducted measurement.
      Remark: LISN=Read Level+ Cable Loss+ LISN Factor

7.3.3 Measurement Procedure and Data
      a. For below 1GHz, the EUT was placed on the top of a rotating table 0.8 meters above the ground at
      a 3 or 10 meter semi-anechoic chamber. The table was rotated 360 degrees to determine the position
      of the highest radiation.
      b. For above 1GHz, the EUT was placed on the top of a rotating table 1.5 meters above the ground at
      a 3 meter fully-anechoic chamber. The table was rotated 360 degrees to determine the position of the
      highest radiation.
      c. The EUT was set 3 or 10 meters away from the interference-receiving antenna, which was
      mounted on the top of a variable-height antenna tower.
      d. 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.
      e. 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.
      f. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum
      Hold Mode.
      g. 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.
      h. Test the EUT in the lowest channel, the middle channel, the Highest channel.
      i. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and
      found the X axis positioning which it is the worst case.
      j. Repeat above procedures until all frequencies measured was complete.
      Remark 1: Level= Read Level+ Cable Loss+ Antenna Factor- Preamp Factor
      Remark 2: For frequencies above 1GHz, the field strength limits are based on average limits.
      However, 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. For the emissions
      whose peak level is lower than the average limit, only the peak measurement is shown in the report.

      e. 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.
      f. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum
      Hold Mode.
      g. 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.
      h. Test the EUT in the lowest channel, the middle channel, the Highest channel.
      i. The radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, and
      found the X axis positioning which it is the worst case.
      j. Repeat above procedures until all frequencies measured was complete.
      Remark 1: Level= Read Level+ Cable Loss+ Antenna Factor- Preamp Factor
      Remark 2: For frequencies above 1GHz, the field strength limits are based on average limits.
      However, 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. For the emissions
      whose peak level is lower than the average limit, only the peak measurement is shown in the report.

7.5.3 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: For frequencies above 1GHz, the field strength limits are based on average limits. However,
      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. For the emissions whose
      peak level is lower than the average limit, only the peak measurement is shown in the report.
