Abstract This paper based on international standard CISPR 16-1-2 introduced and
analyzed structures,parameters,calibration and applications of current probe that used
for electromagnetic interference (EMI) testing. And listed a standard test setup that
use current probe for EMI test, introduced the matters that should be cared when
utilize current probe to do test.
Key words electromagnetic interference (EMI);current probe; transfer impedance ;
transfer admittance ; calibration
