美國FCC認(rèn)證:電子電器產(chǎn)品強制性安全認(rèn)證,主要檢測EMC(電磁兼容)。今天我們主要來講講手機FCC認(rèn)證標(biāo)準(zhǔn)。
手機fcc認(rèn)證標(biāo)準(zhǔn):
1、輻射曝光(RF EXPOSURE)
適用標(biāo)準(zhǔn)§1.1310 and §2.1093
根據(jù)FCC PART 2.1093 ,手機產(chǎn)品需要做SAR,具體限值如下:
參考資料OET65 , 測試方法參考IEEE1528
2、輸出功率測試(RF OUTPUT POWER)
適用標(biāo)準(zhǔn)§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.
測試方法:傳導(dǎo)式輸出功率(Conducted Power)和輻射式輸出功率(Radiated Power)
3、占用帶寬(OCCUPIED BANDWIDTH)
適用標(biāo)準(zhǔn)§2.1049, §22.917, §22.905 and §24.238.
所需測試項目為 26 dB & 99% bandwidth
4、天線端雜散測試(SPURIOUS EMISSION AT ANTENNA TERMINAL)
適用標(biāo)準(zhǔn)§2.1051, §22.917(a) and §24.238(a)
測試方法:傳導(dǎo)式測試法
限值=輸出功率-( 43 + 10 Log10 (power out in Watts))=-13dBm
5、輻射雜散測試(SPURIOUS RADIATED EMISSION)
適用標(biāo)準(zhǔn)§2.1053, 22.917 and § 24.238
測試方法:輻射式測試法
限值=輸出功率-( 43 + 10 Log10 (power out in Watts))=-13dBm
6、頻率范圍邊緣測試(BAND EDGE)
適用標(biāo)準(zhǔn)§ 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、頻率穩(wěn)定度測試(FREQUENCY STABILITY)
適用標(biāo)準(zhǔn) § 2.1055 (a), § 2.1055 (d), §22.355, §24.235
限值要求:§ 2.1055 (a), § 2.1055 (d),
8、峰值與平均值有效比
(Peak-to Average Ratio 即 CREST FACTOR)
適用標(biāo)準(zhǔn):§ 24.232 (d)
限值要求:Peak-to Averag
