How to Locate Sources of Emissions for EMI Troubleshooting Using an MDO4000
Given the approximate frequency of EMI, these techniques will help track down the source of transient RF emissions. They employ a near-field probe with the MDO4000 integrated oscilloscope and spectrum analyzer. Use triggers to focus on RF transients and use RF amplitude traces to look for timing patterns. See how probing analog time-domain signals, while examining RF amplitude traces, can point to the source of emissions.
