2.1 TEST FACILITY 
  The test facilities used to collect the test data in this report is SR01/SR03  at the location of 

No.3,Jinshagang 1st Road, ShiXia, Dalang Town,Dong Guan, China.523792. 

 
2.2 MEASUREMENT UNCERTAINTY   
 

Where relevant, the following measurement uncertainty levels have been estimated 
for tests performed on the EUT as specified in CISPR 16-4-2: 

 
The reported uncertainty of measurement y  ±  U，where expended uncertainty U is based on a 
standard uncertainty multiplied by a coverage factor of    k=2，providing a level of confidence of 
approximately 95 %。
