VCCI EMC测试要求课件.ppt

什么是VCCI VCCI 是日本的电磁兼容认证标志，由日本电磁干扰控制委员会 (Voluntary Control Council for Interference by Information Technology Equipment) 管理，根据 CISPR 22 评估信息技术产品是否符合 VCCI 要求。?? VCCI 认证是非强制性的，但是在日本销售的信息技术产品，一般会被要求进行 VCCI 认证。制造商首先应申请成为 VCCI 的成员，才可以使用 VCCI 标志。为了获得 VCCI 的认可，所提供的 EMI 测试报告必须由 VCCI 注册认可的测试机构签发。 VCCI会员 制造商需成为VCCI的成员才能使用VCCI标签，全球的制造商只要交纳入会费和一年一次的会员费就可以成为次组织的成员。 注册设备需经过相关的测试。设备测试项目在美国测试或者是在世界各地。在通过了VCCI的测试要求后，将颁发证书。 落地式设备的传导测试布置要求 组合式设备的传导测试布置要求 桌上式设备的辐射测试布置要求 落地式设备的辐射测试布置要求 组合式设备的辐射测试布置要求 落地式设备的线缆布置要求 同耀的落地式设备布置样图 V - 3 / 2011. 04必威体育精装版要求 ANSI C63.4:2003 and ANSI C63.4;2009 : American National Standard for Method of Measurement of Radio Noise Emissions from Low Voltage Electrical and Electronic Equipment in the Range 9 kHz to 40 GHz. 信号端口补充定义： The following is not considered a telecommunications/network port under this definition. ? A port generally intended for interconnection of components of an ITE system under test (e.g. RS-232, IEEE Standard 1284 (parallel printer), USB IEEE Standard 1394 (“Fire Wire”), HDMI ,etc.) ? A port used in accordance with instruction manual and the like which clearly specifies things such as specific equipment to be connected to it V - 3 / 2011. 04必威体育精装版要求 4) Without decoupling the AE from the EUT, measure the common mode current with a current probe and measure the common mode voltage with a capacitive voltage probe. 5) The AE shall be device(s) typically connected to the telecommunication port under test by a multiconductor cable specified by the manufacturer, or alternatively, a telecommunications port simulation device, or an active device necessary to appropriately exercise the port under test. 6) If AE is not necessary a device that passively terminates the port shall be connected at the AE end of the cable V - 3 / 2011. 04必威体育精装版要求 7. Test Report Record the measurement result converted to 3m, in frequency above 1GHz. For measurement at telecommunication ports, operating conditions include, for example, state of communication with associated equipme
