          4. The LISN provides 50 ohm coupling impedance for the measuring instrument.
          5. The FCC states that a 50 ohm, 50 microhenry LISN should be used.
          6. Both sides of AC line were checked for maximum conducted interference.
          7. The frequency range from 150 kHz to 30 MHz was searched.
          8. Set the test-receiver system to Peak Detect Function and specified bandwidth (IF Bandwidth =
              9kHz) with Maximum Hold Mode. Then measurement is also conducted by Average Detector
              and Quasi-Peak Detector Function respectively.

3.4.3 Test Procedures
         1.    Configure the EUT according to ANSI C63.10. The EUT was placed on the top of the turntable
               0.8 meter above ground. The phase center of the loop receiving antenna mounted antenna tower
               was placed 3 meters far away from the turntable.
         2.    Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to
               determine the position of the highest radiation.
         3.    The height of the receiving antenna was fixed at one meter above ground to find the maximum
               emissions field strength.
         4.    For Fundamental emissions, use the receiver to measure QP reading.
         5.    When the radiated emissions limits are expressed in terms of the average value of the emissions,
               and pulsed operation is employed, the measurement field strength shall be determined by
               averaging over one complete pulse train, including blanking intervals, as long as the pulse train
               does not exceed 0.1 seconds. As an alternative (provided the transmitter operates for longer
               than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field
               strength shall be determined from the average absolute voltage during a 0.1 second interval
               during which the field strength is at its maximum value.
         6.    Compliance with the spectrum mask is tested with RBW set to 9kHz.
               Note: Emission level (dBμV/m) = 20 log Emission level (μV/m).

           Attenuation                                     Auto
           Frequency Range: 9kHz~150kHz                    RBW 200Hz for QP
           Frequency Range: 150kHz~30MHz                   RBW 9kHz for QP
           Frequency Range: 30MHz~1000MHz                  RBW 120kHz for Peak
         Note: The emission limits shown in the above table are based on measurements employing a CISPR
         quasi-peak detector except for the frequency bands 9-90 kHz, 110-490 kHz. Radiated emission limits
         in these two bands are based on measurements employing an average detector.

3.5.4 Test Procedures
         1.    Configure the EUT according to ANSI C63.10. The EUT was placed on the top of the turntable
               0.8 meter above ground. The phase center of the receiving antenna mounted on the top of a
               height-variable antenna tower was placed 3 meters far away from the turntable.
         2.    Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to
               determine the position of the highest radiation.
         3.    The height of the broadband receiving antenna was varied between one meter and four meters
               above ground to find the maximum emissions field strength of both horizontal and vertical
               polarization.
         4.    For each suspected emissions, the antenna tower was scan (from 1 M to 4 M) and then the
               turntable was rotated (from 0 degree to 360 degrees) to find the maximum reading.
         5.    Set the test-receiver system to Peak or CISPR quasi-peak Detect Function with specified
               bandwidth under Maximum Hold Mode.
         6.    When the radiated emissions limits are expressed in terms of the average value of the emissions,
               and pulsed operation is employed, the measurement field strength shall be determined by
               averaging over one complete pulse train, including blanking intervals, as long as the pulse train
               does not exceed 0.1 seconds. As an alternative (provided the transmitter operates for longer
               than 0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field
               strength shall be determined from the average absolute voltage during a 0.1 second interval
               during which the field strength is at its maximum value.
         7.    In case the emission is lower than 30MHz, loop antenna has to be used for measurement and
               the recorded data should be QP measured by receiver. Antenna Requirements

3.6 Antenna Requirements
3.6.1 Standard Applicable
         Except for special regulations, the Low-power Radio-frequency Devices must not be equipped with
         any jacket for installing an antenna with extension cable. 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 shall be considered sufficient to comply with the provisions of this Section. The
         manufacturer may design the unit so that the user can replace a broken antenna, but the use of a
         standard antenna jack or electrical connector is prohibited.
         The use of a permanently attached antenna or of an antenna that uses a unique coupling to the
         intentional radiator shall be considered sufficient to comply with the rule.



3.6.2 Antenna Anti-Replacement Construction
         An embedded-in antenna design is used.

5. Uncertainty of Evaluation
       The measurement uncertainties shown below were calculated in accordance with the requirements of
       ANSI 63.10-2013. All the measurement uncertainty value were shown with a coverage K=2 to indicate
       95% level of confidence. The measurement data show herein meets or exceeds the CISPR
       measurement uncertainty values specified in CISPR 16-4-2 and can be compared directly to specified
       limit to determine compliance.

         Note:
         1. The amplitude of spurious emissions which are attenuated by more than 20dB below the
              permissible value has no need to be reported.
         2. Emission level (dBμV/m) = 20 log Emission level (μV/m).
         3. Corrected Reading: Antenna Factor + Cable Loss + Read Level - Preamp Factor= Level.
