Particularly, to measure discontinuous disturbances (clicks), an EMI receiver connected to a disturbance analyzer is needed. The EMI receiver is used to measure the interference in a particular frequency. At the output of the intermediate frequency, the analyzer is connected for the clicks' evaluation. The measurement is repeated at four frequencies. This disturbance analysis can take up to 16 hours for the click evaluation of one device under test. Measurements of electromagnetic interference in the time-domain allow reducing the scan time in comparison to EMI receivers. In this MSc project, a full-time domain EMI measurement system covering the frequency range 150 kHz - 30 MHz is proposed to measure emissions according to CISPR 16-1-1, and perform the discontinuous disturbance analysis as described by UNE 55014.
