Abstract
A method for estimating PCB radiated emissions includes providing a BCI probe and a vector network analyzer; performing a calibration step; performing a measurement step; and performing an estimation step. A transfer impedance of the BCI probe is measured via a clamping device in the procedure of performing a calibration step. A measurement-input transfer function of an object and an output-input transfer function of the object are measured via the BCI probe in the procedure of performing a measurement step. Eventually, radiated emissions of the object can be estimated according to the measurement-input transfer function, the output-input transfer function and the transfer impedance in the procedure of performing an estimation step. The present invention accurately estimates radiated emissions of the object with low cost and high speed.
