【专题】RED指令EN 301 489 -52测试要求
ETSI EN 301 489 -52是欧盟针对蜂窝通讯移动、手持、辅助设备的测试标准，目前欧盟发布RED指令下该标准**终的草案EN 301489-52 V1.1.0, 该标准涵盖了GSM/UTRA/E-UTRA的EMC测试，预计在不久之后将正式发布，替代原来RTTE指令中的EN301489-7/-24，两者之间有一定的差异，主要差异内容如下：
u 第2.1章节，引用标准由原来ETSI EN 301 489-1 (V.1.8.1)变更为ETSI EN 301 489-1 (V2.1.1) (11-2016)；
Ü The following referenced documents are necessary for the application of the present document.
[1] ETSI EN 301 489-1 (V2.1.1) (11-2016): "ElectroMagnetic Compatibility (EMC) standard for radio equipment and services; Part 1: Common technical requirements: Harmonised Standard covering the essential requirements of article 3.1(b) of the Directive 2014/53/EU and Harmonised Standard covering the essential requirements of article 6 of the Directive 2014/30/EU".

手机部分主要增对Channelized Equipment
Ø Transmitter：For channelized equipment the exclusion band shall extend 250 % of the channel width either side of the transmitter centre frequency.
Ø NOTE: Exclusion band of 250 % is based on the ITU Radio Regulations [i.8], as the boundary between OOB and Spurious Domain.
Ø Receiver：
For channelized equipment the exclusion band shall be calculated by using the following formulae:
For the lower edge for the exclusion band:
EXband(lower) = BandRX(lower) – nChWRX
For the upper edge of the exclusion band:
EXband(upper) = BandRX(upper) + nChWRX
For equipment that support multiple channel widths the Channel Width used should be the widest support by the EUT.Where the present document is being used in a stand-alone basis (i.e. with no reference to other relevant radio technology parts of ETSI EN 301 489 series [i.13]), the value of n shall be 1.
