Report No.: C180620Z02-RP1 4. FACILITIES AND ACCREDITATIONS 4.1 FACILITIES All measurement facilities used to collect the measurement data are located at No.10-1, Mingkeda Logistics Park, No.18, Huanguan South Rd., Guan Lan Town, Baoan District, Shenzhen, China The sites are constructed in conformance with the requirements of ANSI C63.10:2013, ANSI C63.7 and CISPR Publication 22. All receiving equipment conforms to CISPR Publication 16-1, “Radio Interference Measuring Apparatus and Measurement Methods.” 4.2 ACCREDITATIONS Our laboratories are accredited and approved by the following accreditation body according to ISO/IEC 17025. USA A2LA China CNAS The measuring facility of laboratories has been authorized or registered by the following approval agencies. USA FCC Japan VCCI(C-4815, R-4320, T-2317, G-10624) Canada INDUSTRY CANADA Copies of granted accreditation certificates are available for downloading from our web site, http://www.ccssz.com 4.3 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: Parameter Uncertainty Radiated Emission, 30 to 200 MHz +/-3.6880dB Test Site : 966(2) Radiated Emissi on, 200 to 1000 MHz +/-3.6695dB Test Site : 966(2) Radiated Emission, 1 to 8 GHz +/-5.1782dB Radiated Emission, 8 to 18 GHz +/-5.2173dB This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2. The measured result is above (below) the specification limit by a margin less than the measurement uncertainty; it is therefore not possible to state compliance based on the 95% level of confidence. However, the result indicates that compliance (non-compliance) is more probable than non-compliance) with the specification limit.
