NOTE: 1.The lower limit shall apply at the transition frequencies.
2.The limit decreases linearly with the logarithm of the frequency in the range 0,15 MHz to
0,50 MHz.
4.1.2 Test Setup
1.The EUT was put on a wooden table which was 0.8 m high above the ground and
connected to the AC mains through the Artificial Mains Network (AMN). Where the mains
cable supplied by the manufacture was longer than 0.8 m, the excess was folded back and
forth parallel to the cable at the center so as to form a bundle no longer than 0.4 m.
2.The EUT was kept 0.4 m from any other earthed conducting surface. Both sides of AC line
were checked to find out the maximum conducted emission levels according to the test
procedure during the conducted emission test.
3.The frequency range from 150 kHz to 30 MHz was investigated.
4.The bandwidth of the test receiver was set at 9 kHz.
5.Pretest for all mode, The test data of the worst case condition(s) was reported on the

The EUT was placed on a turn table which was 0.8 m(above 1GHz, the high was 1.5m) above
the ground. The turn table can rotate 360 degrees to determine the position of the maximum
emission level. The EUT was set 3 m away from the receiving antenna which was mounted on an
antenna tower. The measuring antenna moved up and down to find out the maximum emission
level. It moved from 1 m to 4 m for both horizontal and vertical polarizations.
The EUT was tested in the Chamber Site. It was pre-scanned with a Peak detector from the
spectrum, and all the final readings from the test receiver were measured with the Quasi-Peak
detector.
The bandwidth of the EMI test receiver is set at 120kHz for frequency range from 30MHz to 1000
MHz.
The bandwidth of the Spectrum’s VBW is set at 3MHz and RBW is set at 1MHz for peak
emissions measurement above 1GHz and 1MHz RBW, 10Hz VBW for average emissions
measure above 1GHz, Both PK and AV measure, PK detector is used.
The frequency range from 30MHz to 10th harmonic are checked. and no any emissions were
found from 18GHz to 40 GHz, So the radiated emissions from 18GHz to 40GHz were not record.
Notes: 1. Emission Level = Antenna Factor + Cable Loss + Meter Reading - Preamp Factor.
2. Measurement Uncertainty: ±3.2 dB at a level of confidence of 95%.
3. For emissions above 1GHz, if peak level comply with average limit, then the average
level is deemed to comply with average limit.
4. For emissions below 1GHz, pretest for all mode, The test data of the worst case
condition(s) was reported on the following pages.
5. For Both PK and AV value above 1GHz, PK detector is used.

6. 6DB BANDWIDTH TEST
6.1 Applicable Standard
The bandwidth at 6 dB down from the highest in-band spectral density is measured with a
spectrum analyzer connected to the antenna terminal while the EUT is operating at its maximum
power control level, as defined in KDB 789033, at the appropriate frequencies. The spectrum
analyzer’s bandwidth measurement function is configured to measure the 26 dB bandwidth.
The 26 dB bandwidth is used to determine the conducted power limits.
The minimum of 6dB Bandwidth measurement is 0.5 MHz for U-NII-3
6.2 Test Procedure
1. Emission Bandwidth (EBW)
a) Set RBW = approximately 1% of the emission bandwidth.
b) Set the VBW > RBW.
c) Detector = Peak.
d) Trace mode = max hold.
e) Measure the maximum width of the emission that is 26 dB down from the maximum of the emission.
Compare this with the RBW setting of the analyzer. Readjust RBW and repeat measurement as needed
until the RBW/EBW ratio is approximately 1%.
2. Minimum Emission Bandwidth for the band 5.725-5.85 GHz
Section 15.407(e) specifies the minimum 6 dB emission bandwidth of at least 500 KHz for the band
5.715-5.85 GHz. The following procedure shall be used for measuring this bandwidth:
a) Set RBW = 100 kHz.
b) Set the video bandwidth (VBW) ≥ 3 × RBW.
c) Detector = Peak.
d) Trace mode = max hold.
e) Sweep = auto couple.
f) Allow the trace to stabilize.
g) Measure the maximum width of the emission that is constrained by the frequencies associated with the
two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the
maximum level measured in the fundamental emission.

7.1 Limits
Band 5.725-5.825GHz:
FCC: For the band 5.725-5.85 GHz, the maximum conducted output power over the frequency band of

parameters are adjusted such that the power
is measured only when
the EUT is
transmitting at its maximum power control level. Since the measurement is made only during the ON
time of the transmitter, no duty cycle correction factor is required.

8. DUTY CYCLE
8.1 Test Procedure
The zero-span mode on a spectrum analyzer or EMI receiver if the response time and spacing
between bins on the sweep are sufficient to permit accurate measurements of the on and off times of
the transmitted signal. Set the center frequency of the instrument to the center frequency of the
transmission. Set RBW ≥ OBW if possible; otherwise, set RBW to the largest available value. Set
VBW ≥ RBW. Set detector = peak or average. The zero-span measurement method shall not be used
unless both RBW and VBW are > 50/T and the number of sweep points across duration T exceeds
100. (For example, if VBW and/or RBW are limited to 3 MHz, then the zero-span method of measuring
duty cycle shall not be used if T ≤ 16.7 microseconds.)
The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator.
The path loss was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously.
The EUT was operating in controlled its channel.
Use the following spectrum analyzer settings:
Span = Zero Span
RBW = 8MHz
VBW =50MHz
Number of points in Sweep >100
Detector function = peak
Trace = Clear write Measure Ttotal and Ton
Calculate Duty Cycle = Ton / Ttotal and Duty Cycle Factor=10*log(1/Duty Cycle)

9. PEAK POWER SPECTRAL DENSITY TEST
9.1 Limits
Band 5.725-5.825GHz:
FCC: In addition, the maximum power spectral density shall not exceed 30 dBm in any 500-kHz band.
9.2 Test setup
Methods refer to FCC KDB 789033
1) Create an average power spectrum for the EUT operating mode being tested by following the
instructions in section E)2) for measuring maximum conducted output power using a
spectrum analyzer or EMI receiver: select the appropriate test method (SA-3, or alternatives to each) and
apply it up to, but not including, the step labeled, “Compute power…”.
2) Use the peak search function on the instrument to find the peak of the spectrum.
3) The result is the PPSD.
4) The above procedures make use of 1 MHz resolution bandwidth to satisfy the 1 MHz
measurement bandwidth specified in the 15.407(a)(5). That rule section also permits use of
resolution bandwidths less than 1 MHz “provided that the measured power is integrated to
show the total power over the measurement bandwidth” (i.e., 1 MHz). If measurements are
performed using a reduced resolution bandwidth and integrated over 1 MHz bandwidth
