About Near Field Probes
Near field probes detect electrical or magnetic energy in the field directly around a device under test. These probes are commonly used to perform pre-compliance EMC testing on a product in order to detect the presence of electromagnetic interference, or EMI, exceeding relevant regulatory standards.
