5.5.Test Procedure
The EUT is put on the plane 0.8 m high above the ground by insulating support
and is connected to the power mains through a line impedance stabilization
network (L.I.S.N.). This provides a 50ohm coupling impedance for the EUT
system. Please refer the block diagram of the test setup and photographs. Both
sides of AC lines are checked to find out the maximum conducted emission. In
order to find the maximum emission levels, the relative positions of equipment
and all of the interface cables shall be changed according to ANSI C63.10: 2013
on Conducted Emission Measurement.
The bandwidth of test receiver (R & S ESCS30) is set at 9kHz.
The frequency range from 150kHz to 30MHz is checked.

Measure the dyty cycle(x) of the transmitter output signal as described in
Section 6.0.
Set instrument center frequency to DTS channel center frequency.
Set span to at least 1.5×OBW.
Set RBW to: 3kHz≤ RBW≤100kHz.
Set VBW≥ 3×RBW
Detector=power averaging(RMS) or sample detector(when RMS not available).
Ensure that the number of measurement points in sweep≥2×span/RBW.
Sweep time=auto couple.
Do not use sweep triggering. Allow sweep to “free run”.
Employ trace averaging(RMS) mode over a minimum of 100 traces.
Use the peak maker function to determine the maximum amplitude level.
Add 10log(1/x), where x is the duty cycle measured in step(a, to the measured
PSD to compute the average PSD during the actual transmission time.
If resultant value exceeds the limit, then reduce RBW(no less than 3kHz) and
repeat(note that this may require zooming in on the emission of interest and
reducing the span in order to meet the minimum measurement point requirement
as the RBW is reduced).

1. Emissions attenuated more than 20 dB below the permissible value are not reported.
2. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and
subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows:
Result = Reading + Corrected Factor
3. Display the measurement of peak values.
Test Procedure:
The EUT and its simulators are placed on a turntable, which is 1.5 meter high above
ground(Above 1GHz). The turntable can rotate 360 degrees to determine the position of
the maximum emission level. EUT is set 3.0 meters away from the receiving antenna,
which is mounted on an antenna tower. The antenna can be moved up and down between
1.0 meter and 4 meters to find out the maximum emission level. Broadband antenna
(calibrated bi-log antenna) is used as receiving antenna. Both horizontal and vertical
polarizations of the antenna are set on measurement. In order to find the maximum
emission levels, all of the EUT location must be manipulated according to ANSI
C63.10:2013 on radiated emission measurement. The EUT was tested in 3 orthogonal
planes.
Let the EUT work in TX modes then measure it.
We select 2412MHz, 2462MHz TX frequency to transmit(802.11b/g/n20 mode).
We select 2422MHz, 2452MHz TX frequency to transmit(802.11n40 mode).
During the radiated emission test, the spectrum analyzer was set with the following
configurations:
1.The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 3MHz for peak measurement with peak detector at frequency above 1GHz.
2.The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video
bandwidth is 10Hz for Average measurement with peak detection at frequency above
1GHz.
3.All modes of operation were investigated and the worst-case emissions are reported.

11.4.Configuration of EUT on Measurement
The equipment are installed on Radiated Emission Measurement to meet the commission
requirements and operating regulations in a manner which tends to maximize its emission
characteristics in normal application.
11.5.Operating Condition of EUT
11.5.1.Setup the EUT and simulator as shown as Section 11.1.
11.5.2.Turn on the power of all equipment.
11.5.3.Let the EUT work in TX modes measure it. The transmit frequency are
2412-2462 and 2422-2452MHz. We select 2412MHz, 2437MHz, 2462MHz and
2422MHz, 2437MHz, 2452MHz TX frequency to transmit.
11.6.Test Procedure
The EUT and its simulators are placed on a turntable, which is 0.1 meter high above
ground. The turntable can rotate 360 degrees to determine the position of the maximum
emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted
on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4
meters to find out the maximum emission level. Broadband antenna (calibrated bi-log
antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the
antenna are set on measurement. In order to find the maximum emission levels, all of the
EUT location must be manipulated according to ANSI C63.10:2013 on radiated emission
measurement. The EUT was tested in 3 orthogonal planes.
The worst-case data rate for this channel to be 1Mbps for 802.11b mode and 6Mbps for
802.11g mode and 150Mbps for 802.11n mode, based on previous with 802.11 WLAN
product design architectures.
The frequency range from 30MHz to 25000MHz is checked.
Result = Reading + Corrected Factor
Where Corrected Factor = Antenna Factor + Cable Loss – Amplifier Gain
During the radiated emission test, the spectrum analyzer was set with the following
configurations:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum
analyzer is 120kHz for Quasi-peak at frequency below 1GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz
and video bandwidth is 3MHz for peak measurement with peak detector
at frequency above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz
and video bandwidth is 10Hz for Average measurement with peak
detection at frequency above 1GHz.

4. All modes of operation were investigated and the worst-case emissions
are reported.
11.7.The Field Strength of Radiation Emission Measurement Results
Note: 1. Emissions attenuated more than 20 dB below the permissible value are not reported.
2. *: Denotes restricted band of operation.
3. The EUT is tested radiation emission at each test mode (802.11 b/g/n) in three axes. The worst emissions are
reported in all test mode and channels.
4.We tested 802.11b,g,n mode and recorded the worst case data(802.11b) for radiated emission test below 1GHz.
5.The radiation emissions from l8-25GHz are not reported, because the test values lower than the limits of 20dB.
