When debugging electromagnetic interference (EMI) problems, the electronic design engineer faces the challenging problem of identifying the sources of unwanted emissions and developing a solution for them. Often, the only information that comes back from the EMC test laboratory is a spectrum curve indicating the frequencies where emissions are critical or violating the limits. The R&S®RTO / R&S®RTE digital oscilloscope is a valuable tool for analyzing EMI problems in electronic designs. High input sensitivity, high dynamic range and a powerful FFT implementation are key features for capturing and analyzing unwanted emissions.
