2.1. Report information
This report is not a certificate of quality; it only applies to the sample of the specific product/equipment given at the time of its testing. The results are not used to indicate or imply that they are application to the similar items. In addition, such results must not be used to indicate or imply that SMQ approves recommends or endorses the manufacture, supplier or use of such product/equipment, or that SMQ in any way guarantees the later performance of the product/equipment.
The sample/s mentioned in this report is/are supplied by Applicant, SMQ therefore assumes no responsibility for the accuracy of information on the brand name, model number, origin of manufacture or any information supplied.
Additional copies of the report are available to the Applicant at an additional fee. No third part can obtain a copy of this report through SMQ, unless the applicant has authorized SMQ in writing to do so.
The lab will not be liable for any loss or damage resulting for false, inaccurate, inappropriate or incomplete product information provided by the applicant/manufacturer.
2.2. Laboratory Accreditation and Relationship to Customer
The testing report were performed by the Shenzhen Academy of Metrology and quality Inspection EMC Laboratory (Guangdong EMC compliance testing center), in their facilities located at NETC Building, No.4 Tongfa Rd., Xili, Nanshan, Shenzhen, China. At the time of testing, Laboratory is accredited by the following organizations:

3. GENERAL INFORMATION
Over the Air Measurements (Active) are performed in a Satimo SG-24. The SG-24 has 23 probe antennas mounted with equal spacing on a circular arch. Electronic switching of the probe antennas provides outstanding measurement speed. The geometry of the setup, with only a Styrofoam column within 1.6 meters of the EUT, ensures minimum interference and low ripple on the measured radiation patterns.
Figure 1­ SG-24. The DUT is placed on top of the pedestal, in the center of the system.
4. TEST PROCEDURE
The gain of the antenna was measured in the anechoic chamber Satimo SG24. The chamber provides less than ­30 dB reflectivity from 400 MHz through 6 GHz. The chamber size is:8m*5m*5m. The measurement results are calibrated using a dipole antenna. The antenna gain and efficiency are measured with AUT placed in the chamber.
