Radiated electric and magnetic emissions from trains have been measured from a fixed position 10 m from the railway track according to the preliminary European standards ENV 50121-1, -2, -3. In order to investigate alternative ways of measuring radiated emissions from trains, a number of different measuring set ups have been tried. The antenna positions have been both by the railway track, on board the train, and also, for comparison of different methods of transient recording, in a shielded chamber. Recordings have been made with a measuring receiver, a spectrum analyzer and a digital oscilloscope, in combinations with different broadband antennas. The conclusion is that it seems feasible to measure radiated emissions from trains, with the recording equipment and the antennas on board the train. This method is less costly compared to measurements from a fixed position by the track. The recording equipment can be a spectrum analyzer for recordings of frequency spectra but a digital oscilloscope is necessary for transient recordings. A measuring receiver, on the other hand, is too slow for registration of transients. A proposal is made on how a measuring car can be equipped, to make the measuring results relatively independent of the surroundings of the railway track.
