Real-time railway EMC measurments to EN 50121

Railway rollling stock testing according to EN 50121-3-1 made easy with two receivers measureing in parallel. The R&S®EPL captures the magnetic field (150 kHz to 30 MHz) while at the same time the R&S®ESW captures the electric field (30 MHz to 1 GHz) - both in real-time, displaying the results in a spectrogram view. This not only enables fast measurements with a minimum of railway operation required, but also helps identifying all emission sources in detail.

The video presents railway rolling stock tests with highest speed and a minium of train passes required. Fast receivers and capable antennas enable quick and easy results.
