    Conducted interference caused by equipment connected to power supply networks, and the interference in these networks, is conventionally measured using (slow) scanning tuned electromagnetic interference (EMI) receivers. A voltage sensor which separates common mode and differential mode in a three-phase setup combined with a 8-channel digital oscilloscope allows measuring voltage and current via many samples in the three phases plus neutral. Using fast fourier transform for the data processing the conventional amplitude-as-function-of-frequency plots, similar to what would be obtained using conventional EMI receivers, can be generated. But with the presented measurement technique it is also possible to present time-frequency plots in a waterfall diagram. The time - domain measurement technique shows that the conducted noise is cyclic short-time interference
