EMC lab is subordinate to the institute of reliability testing and energy efficiency testing which is one of the branch of SIMS/NRC. It is the first EMC testing institution legally set up by the metrological administrative department of the Chinese government in the western region. It includes three parts: an anechoic chamber(282 m2), a shielding chamber (40 m2)and a power amplifier control room(38 m2).The laboratory temperature is 23 ± 0.5 ℃, and the humidity is 40% RH.
