Abstract :
An overview over the time-domain measurement techniques for spatially resolved measurement of radiated EMI is given. Time-domain electromagnetic interference (EMI) measurement systems sample the broad-band EMI signal with GHz sampling rates. Assuming stationary noise processes all data can be retrieved from two-channel-measurements. The high speed of TDEMI systems allows efficient spatially resolved measurement of the field correlations.
