Rigol NFP-3 – Near Field Probe Kit

The Rigol NFP-3 Near Field Probe Kit delivers rapid identification and localization of electromagnetic interference sources across PCBs, cables, and enclosures. Four specialized magnetic field probes operate from 30 MHz to 3 GHz, enabling engineers to pinpoint EMI radiation, measure interference intensity and frequency content, and conduct EMC pre-compliance testing before formal certification. Each probe offers distinct detection capabilities—from the NFP-3-P1’s 10 cm range for general magnetic field leakage detection to the NFP-3-P4’s 2 mm resolution for high-precision PCB wiring and vertically emitted field analysis. The kit connects directly to spectrum analyzers and oscilloscopes via a 50 Ω SMB interface, eliminating the need for dedicated test equipment.
