美国FCC认证:电子电器产品强制性安全认证,主要检测EMC(电磁兼容)。今天我们主要来讲讲手机FCC认证标准。
手机fcc认证标准:
1、辐射曝光(RF EXPOSURE)
适用标准§1.1310 and §2.1093
根据FCC PART 2.1093 ,手机产品需要做SAR,具体限值如下:
参考资料OET65 , 测试方法参考IEEE1528
2、输出功率测试(RF OUTPUT POWER)
适用标准§2.1046 and §22.913 (a), and §2.1046 and §24.232 (C)
限值要求:(1)According to FCC §2.1046 and §22.913 (a), the ERP of mobile transmitters and auxiliary test transmitters must not exceed 7 watts.
(2)According to FCC §2.1046 and §24.232 (C), in no case may the peak output power of a base station transmitter exceed 2 watt EIRP.
测试方法:传导式输出功率(Conducted Power)和辐射式输出功率(Radiated Power)
3、占用带宽(OCCUPIED BANDWIDTH)
适用标准§2.1049, §22.917, §22.905 and §24.238.
所需测试项目为 26 dB & 99% bandwidth
4、天线端杂散测试(SPURIOUS EMISSION AT ANTENNA TERMINAL)
适用标准§2.1051, §22.917(a) and §24.238(a)
测试方法:传导式测试法
限值=输出功率-( 43 + 10 Log10 (power out in Watts))=-13dBm
5、辐射杂散测试(SPURIOUS RADIATED EMISSION)
适用标准§2.1053, 22.917 and § 24.238
测试方法:辐射式测试法
限值=输出功率-( 43 + 10 Log10 (power out in Watts))=-13dBm
6、频率范围边缘测试(BAND EDGE)
适用标准§ 22.917(a) and §24.238(a)
限值要求:the power of any emissions outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB.
7、频率稳定度测试(FREQUENCY STABILITY)
适用标准 § 2.1055 (a), § 2.1055 (d), §22.355, §24.235
限值要求:§ 2.1055 (a), § 2.1055 (d),
8、峰值与平均值有效比
(Peak-to Average Ratio 即 CREST FACTOR)
适用标准:§ 24.232 (d)
限值要求:Peak-to Averag
