1.4. Statement of the measurement uncertainty
The data and results referenced in this document are true and accurate. The reader is cautioned that
there may be errors within the calibration limits of the equipment and facilities. The measurement
uncertainty was calculated for all measurements listed in this test report acc. to CISPR 16 - 4
“Specification for radio disturbance and immunity measuring apparatus and methods – Part 4:
Uncertainty in EMC Measurements“ and is documented in the Shenzhen CTL Testing Technology Co.,
Ltd. quality system acc. to DIN EN ISO/IEC 17025. Furthermore, component and process variability of
devices similar to that tested may result in additional deviation. The manufacturer has the sole
responsibility of continued compliance of the device.

Hereafter the best measurement capability for CTL laboratory is reported:

TEST CONFIGURATION




TEST PROCEDURE

1.     The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
       manual. The EUT is a tabletop system; a wooden table with a height of 0.8 meters is used and is placed on
       the ground plane as per ANSI C63.10:2013.
2.     Support equipment, if needed, was placed as per ANSI C63.10:2013.
3.     All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10:2013.
4.     The adapter received AC120V/60Hz power through a Line Impedance Stabilization Network (LISN) which
       supplied power source and was grounded to the ground plane.
5.     All support equipments received AC power from a second LISN, if any.
6.     The EUT test program was started. Emissions were measured on each current carrying line of the EUT
       using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two
       monitoring points:    Line 1 (Hot Side) and Line 2 (Neutral Side).   Two scans were taken:   one with Line 1
       connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1
       connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.
7.     Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
8.     During the above scans, the emissions were maximized by cable manipulation.

Test Procedure

1.     Below 1GHz measurement the EUT is placed on a turntable which is 0.8m above ground plane,
       and above 1GHz measurement EUT was placed on a low permittivity and low loss tangent turn
       table which is 1.5m above ground plane.
2.     Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating
       the turn table from 0℃ to 360℃ to acquire the highest emissions from EUT
3.     And also, each emission was to be maximized by changing the polarization of receiving antenna
       both horizontal and vertical.
4.     Repeat above procedures until all frequency measurements have been completed.
5.     Radiated emission test frequency band from 9KHz to 1000MHz.
6.     The distance between test antenna and EUT as following table states:

Remark:
1. Data of measurement within this frequency range shown “-- in the table above means the reading
   of emissions are attenuated more than 20dB below the permissible limits and not recorded.
2. The test limit distance is 3m limit.
3. PK means Peak Value, QP means Quasi Peak Value, AV means Average Value.
4. F means Fundamental Frequency.
5. Emission level (dBuV/m) =Reading + Antenna Factor + Cable Loss.
6. Margin value = Limit value- Emission level.

3.3. 20dB Bandwidth
Limit
The 20dB bandwidth shall be less than 80% of the permitted frequency band.

Test Procedure

The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth
of the fundamental frequency was measured by spectrum analyzer with 30 KHz RBW and 100 KHz
VBW.
The 20dB bandwidth is defined as the total spectrum the power of which is higher than peak power
minus 20dB.
