1、RE:輻射發射(RE)(100k~2.7G)Radiated Emission :輻射騷擾測試
2、CE:傳導幹擾CE(conduction emission)(150kHz~108MHz):傳導騷擾測試
3、RS:輻射抗擾:射頻電磁場輻射抗擾度測試
4、CS:傳導抗幹擾:射頻場感應的傳導騷擾抗擾度測試
5、EFT:瞬態脈沖幹擾:電快速瞬變脈沖群抗擾度測試
6、DIP:電壓跌落:電壓暫降,短時中斷和電壓變化抗擾度測試
7、ESD:靜電:靜電抗擾度測試
8、Surge:浪湧:抗擾度浪湧(沖擊)抗擾度測試
關於RE和RSE的區別:
輻射雜散(簡稱RSE)是指當移動臺與非輻射性純阻負載相連接或者在接收機狀態時,由移動臺產生或放大的通過移動臺機殼、電源、控制設備、音頻各電纜輻射的工作頻率外上的發射。
在目前的國際標准中“輻射雜散”基本都將其劃分在了射頻項目(RF)裏面,而國內標准(以YD1032為典型)則將其劃分在電磁兼容(EMC)的測試內容內。
從RSE的定義可以看出,RSE測量的不僅僅是發信機發出來的噪聲,它覆蓋的是整個雜散域,既包含有意發射,也包含EUT中與發信機無關的其它電路的無意發射。3GPP標准頒布以後,RSE測試成為衡量無線產品EMI性能的重要測試。與此同時,不難發現,RE和RSE測試的考察範圍存在著重疊。
