Troubleshooting with Near-Field Probes
101060710317001031600 Troubleshooting with Near-Field ProbesThe electro magnetic interference (EMI) compliance testing consists of a far-field emissions measurement. There is no definitive relationship between near- and far-field measurements. Though near-field measurements generally don't directly correlate with far-field measurements, the near-field measurement is still an excellent troubleshooting tool. The signal strength in the near field is related to the square of the distance from the source. By getting in close, a particular noise source can be pinpointed thanks to the strong sensitivity to distance from …
