EMI debugging at board level

March 29, 2020
Analyze near-field signals and reduce electromagnetic interference (EMI) on boards and modules with the R&S®SpectrumRider FPH and the R&S®HZ-15 near-field probes.

Digital oscilloscopes in combination with near-field probe sets are powerful instruments for debugging during design. They allow designers to quickly locate and analyze EMI problems early on. High dynamic range and a high input sensitivity of 1 mV/div ensure that even weak emissions can be analyzed. The R&S®RTO fast Fourier transformation (FFT) implementation provides a fast update rate and the FFT frame overlay processing and persistence display provides insights into the structure of unwanted emissions.
