Validation of low-level, high-frequency transient FDTD simulation with radiated field measurements

Validation of numerical simulation results for low-level, high-frequency transient radiated EMC signals is difficult because of the limitations of time domain measurement instruments. A measurement method combining the sensitivity of a RF spectrum analyzer and the time domain abilities of a digitizing oscilloscope is used to validate FDTD simulations of a fast transient coupled between two antennas inside a car.
