Near Field Probes

Near field probes are only sensitive to sources at close proximity. They are generally immune to background noise or hand position. Once emission source has been located, the appropriate fix can be implemented to reduce emissions. Since the near field probe measurements do not provide any indication of compliance, the measurement must be retaken with an antenna at the specified distance. Near Field Probe measurement do not take into account any other contributors to higher radiated emissions levels at the specified distance. In addition, Near Field Probes can be a valuable tool for troubleshooting EMI problems at the factory. They do not require any special calibrated test facility.

Near-field magnetic (H-field) and electric (E-field) probes let you “sniff” around the circuits, cables, and enclosures to find the source and are included in the sets.
