(3) Distance is the distance in meters between the measuring instrument, antenna and the closest point of any part of the device or system. (4) 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 and above 1000MHz. Radiated emission limits in these three bands are based on measurements employing an average detector. 4.4. EUT Configuration on Test The following equipment are installed on Radiated Emission Test to meet the commission requirements and operating regulations in a manner which tends to maximize its emission characteristics in normal application.

4.4.1. WiFi module (EUT)

Model Number Serial Number 4.5. Operating Condition of EUT

: U9W43 : N/A

4.5.1. Setup the EUT and simulator as shown as Section 4.2.

4.5.2. Turn on the power of all equipments.

4.5.3. Let EUT work in BLE Tx mode.
4.6. Test Procedure Frequency below 30MHz: The EUT setup on the turn table which has 0.8 m height to the ground. The turn table rotated 360 degrees and antenna fixed to 1 m to find the maximum emission level. In order to find the maximum emission, all of the interface cables were manipulated according to ANSI C63.10: 2020 regulation. EUT and its simulators are placed on a turn table, which is 0.8 meter high above ground for frequency 30MHz~1000MHz, 1.5 meter high above ground for frequency above 1GHz and put the absorbing with 2.4m(L)*2.4m(W)*0.3m(H) on the ground . The turn table can rotate 360 degrees to determine the position of the maximum emission level. Power on the EUT and let it working in test mode, then test it.EUT is set 3 meters away from the receiving antenna, which is mounted on a antenna tower. The antenna can be moved up and down between 1 meter and 4 meters to find out the maximum emission level. Broadband antenna (calibrated bilog antenna) is used as receiving antenna for frequency 30MHz~1000MHz, and the Horm antenna is used as receiving antenna for frequency above 1GHz. Both horizontal and vertical polarization of the antenna is set on Test. In order to find the maximum emission levels, all of the interface cables must be manipulated according to ANSI C63.10: 2020 on radiated emission Test.

This test was performed with EUT in X, Y, Z position, and the worse case was found reported in report.
The bandwidth of the EMI test receiver (R&S ESR3) is set at 120kHz for frequency range from 30MHz to 1000 MHz.
The bandwidth of the Spectrum's RBW is set at 1MHz and VBW is set at 3MHz for peak emissions measurement above 1GHz.
This device is pulse Modulated, a duty cycle factor was used to calculated average level based measured peak level.
The frequency range from 30MHz to 10th harmonic (25GHz) are checked. and no any emissions were found from 18GHz to 25 GHz, So the radiated emissions from 18GHz to 25GHz were not record.
4.7. Radiated Emission Test Results PASS.
All the emissions from 30MHz to 25GHz were comply with the 15.209 Limit. Note: The duty cycle factor for calculate average level is -0.997dB for BLE, and average limit
is 20dB below peak limit, so if peak measured level comply with average limit, the average level was deemed to comply with average limit.

8.3. Test Produce

Use the test method descried in ANSI C63.10 clause 6.10: For upper band emissions that are up to two bandwidths(2MHz) away (2483.5MHz to 2485.5MHzfrom the band-edge use below produce: 1. Choose a spectrum analyzer span that encompasses both the peak of the fundamental
emission and the band-edge emission under investigation. Set the analyzer RBW to 100KHz and with a video bandwidth 300KHz. Record the peak levels of the fundamental emission and the relevant band-edge emission, Observe the stored trace and measure the amplitude delta between the peak of the fundamental and the peak of the band-edge emission. This is not a field strength measurement, it is only a relative measurement to determine the amount by which the emission drops at the band edge relative to the highest fundamental emission level. 2. Subtract the delta measured in step (1) from the maximum field strengths measured in clause 4 .The resultant field strengths are then used to determine band-edge compliance as required by Section 15.205 For emissions above two bandwidths away from the band-edge use below produce: 1. The EUT is placed on a turntable, which is 0.8m above the ground plane and worked at
highest radiated power. 2. The turntable was rotated for 360 degrees to determine the position of maximum emission
level. 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find
out the highest emission. 4. Set the spectrum analyzer in the following setting in order to capture the lower and
upperband-edges of the emission: (a) PEAK: RBW=1MHz ;VBW=3MHz, PK detector, Sweep=AUTO (b) This is pulse Modulation device a duty cycle factor was used to calculate average
level based measured peak level.
8.4. Test Results

Pass (The testing data was attached in the next pages.) Note: If the PK measured levels comply with average limit, then the average level were deemed
to comply with average limit.
