Immunity measurements are performed in general by the application of

49、 a wanted test signal and an unwanted signal to the EUT. The fundamental basis of the measurement is set out in this clause, together with a listing of conditions which need to be specified in the detailed recommendations produced by the CISPR product committees. Clause 5 deals with the general principals of conduction methods of measurement for immunity, and clause 6 with radiation met
