Overview

RIGOL's NFP-3 is a high-performance near-field probe set, exclusively designed to pair with RIGOL DSA series spectrum analyzers for precise EMI (Electromagnetic Interference) testing. It enables accurate detection of magnetic field strength on electronic component surfaces, identification of magnetic coupling channels, and analysis of the magnetic field environment around modules.

Key Features

4 Specialized Probe Sub-Models: Covers diverse detection needs with tailored ranges (from micro-scale components to large modules).

Wide Frequency Coverage: 30MHz to 3GHz frequency range, compatible with most consumer and industrial electronic EMI testing scenarios.

Complete Connectivity Kit: Includes SMB (male) port (for direct probe connection), N (male)-BNC (female) adapter, and 1000mm BNC (male)-SMB (female) RF cable—ensuring seamless pairing with RIGOL DSA analyzers.

Stable Signal Transmission: 50Ω impedance matches industry standards, minimizing signal loss during detection.

Selection Tips

The NFP-3 is a 4-probe set (not separate SKUs), making it the all-in-one solution if you need to:

Test magnetic fields across scales—from large modules (use P1) to micro-components (use P4).

Cover diverse EMI testing scenarios (e.g., initial broad-range scanning with P1, then precise pin-level detection with P4).

Pair with RIGOL DSA series spectrum analyzers for consistent, reliable interference localization.

Avoid purchasing multiple single probes separately (cost-effective and comprehensive).

Application Scenarios

Consumer Electronics EMI Testing: Detect magnetic interference in smartphones, laptops, or TVs—use P4 for chip pins, P1 for overall device scanning.

Industrial Module Debugging: Analyze magnetic fields in power modules or control boards—P2 for mid-sized inductors, P3 for connector areas.

Automotive Electronics Testing: Check magnetic coupling in automotive ECUs (Electronic Control Units)—P3 for PCB traces, P4 for sensor pins.

Research Lab Experiments: Conduct precise magnetic field mapping for new electronic prototypes—mix P1-P4 to cover full scale.

Manufacturing Quality Control: Verify EMI compliance of mass-produced devices—P1 for quick batch scanning, P4 for faulty unit pinpointing.

PCB Design Optimization: Identify magnetic hotspots on PCBs—P3 for trace testing, P4 for SMD component validation.
