Conducted Immunity is synonymous with conducted susceptibility.  It is the ability of an electrical device to withstand radio frequency interference on its power leads or interconnecting signal conductors.  Conducted Immunity is also a term referring to EMI tests wherein the electrical device is subjected to interference signals injected on its power leads or interconnecting signal conductors. 

Conducted immunity signals may be inductively coupled, capacitively coupled, or directly injected. 

In EMI Analyst, conducted immunity is referred to as conducted susceptibility and is abbreviated, "CS".
