3.8 Radiated Band Edges and Spurious Emission Measurement
3.8.1 Limit of Radiated Band Edges and Spurious Emission
         In any 100 kHz bandwidth outside the intentional radiator frequency band, all harmonics/spurious
         must be at least 20 dB below the highest emission level within the authorized band. In addition,
         radiated emissions which fall in the restricted bands must also comply with the limits as below.

3.8.3 Test Procedures
          1.     The EUT was placed on a turntable with 0.8 meter for frequency below 1GHz and 1.5 meter for
                 frequency above 1GHz respectively above ground.
          2.     The EUT was set 3 meters from the interference receiving antenna, which was mounted on the
                 top of a variable height antenna tower.
          3.     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 turntable (from 0 degree to 360 degrees) to find the
                 maximum reading. A pre-amp and a high pass filter are used for the test in order to get better
                 signal level to comply with the guidelines.
          4.     Set to the maximum power setting and enable the EUT transmit continuously.
          5.     Use the following spectrum analyzer settings:
                 (1)   Span shall wide enough to fully capture the emission being measured;
                 (2)   Set RBW=100 kHz for f < 1 GHz, RBW=1MHz for f>1GHz ; VBW  RBW; Sweep = auto;
                       Detector function = peak; Trace = max hold for peak
                 (3)   For average measurement: use duty cycle correction factor method per 15.35(c).
                       Duty cycle = On time/100 milliseconds
                       On time = N1*L1+N2*L2+...+Nn-1*LNn-1+Nn*Ln
                       Where N1 is number of type 1 pulses, L1 is length of type 1 pulses, etc.
                       Average Emission Level = Peak Emission Level + 20*log(Duty cycle)
          6.     Corrected Reading: Antenna Factor + Cable Loss + Read Level - Preamp Factor = Level
          7.     For testing below 1GHz, if the emission level of the EUT in peak mode was 3 dB lower than the
                 limit specified, then peak values of EUT will be reported, otherwise, the emissions will be
                 repeated one by one using the CISPR quasi-peak method and reported.
          8.     For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than
                 average limit (that means the emission level in average mode also complies with the limit in
                 average mode), then peak values of EUT will be reported, otherwise, the emissions will be
                 measured in average mode again and reported.


         Note: The average levels were calculated from the peak level corrected with duty cycle correction
         factor (-24.82dB) derived from 20log (dwell time/100ms). This correction is only for signals that hop
         with the fundamental signal, such as band-edge and harmonic. Other spurious signals that are
         independent of the hopping signal would not use this correction.

3.8.5 Test Results of Radiated Spurious Emissions (9 kHz ~ 30 MHz)
         The low frequency, which started from 9 kHz to 30MHz, was pre-scanned and the result which was
         20dB lower than the limit line was not reported.

3.9.2 Measuring Instruments
         The measuring equipment is listed in the section 4 of this test report.


3.9.3 Test Procedures
          1. 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.
          2. Connect EUT to the power mains through a line impedance stabilization network (LISN).
          3. All the support units are connecting to the other LISN.
          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.

3.10 Antenna Requirements
3.10.1 Standard Applicable
         If directional gain of transmitting antennas is greater than 6dBi, the power shall be reduced by the
         same level in dB comparing to gain minus 6dBi. 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.


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


3.10.3 Antenna Gain
         The antenna peak gain of EUT is less than 6 dBi. Therefore, it is not necessary to reduce maximum
         peak output power limit.

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.

    1. Level(dBμV/m) =
    Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB)
    2. Over Limit(dB) = Level(dBμV/m) – Limit Line(dBμV/m)


    For Peak Limit @ 2390MHz:
    1. Level(dBμV/m)
    = Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB)
    = 32.22(dB/m) + 4.58(dB) + 54.51(dBμV) – 35.86 (dB)
    = 55.45 (dBμV/m)
    2. Over Limit(dB)
    = Level(dBμV/m) – Limit Line(dBμV/m)
    = 55.45(dBμV/m) – 74(dBμV/m)
    = -18.55(dB)


    For Average Limit @ 2390MHz:
    1. Level(dBμV/m)
    = Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB)
    = 32.22(dB/m) + 4.58(dB) + 42.6(dBμV) – 35.86 (dB)
    = 43.54 (dBμV/m)
    2. Over Limit(dB)
    = Level(dBμV/m) – Limit Line(dBμV/m)
    = 43.54(dBμV/m) – 54(dBμV/m)
    = -10.46(dB)


    Both peak and average measured complies with the limit line, so test result is “PASS”.

                      1. Worst case Duty cycle = on time/100 milliseconds = 2 * 2.87 / 100 = 5.74 %
