NFP-3 Near Field Probe
Product Overview
NFP-3 is used with RIGOL DSA series spectrum analyzer for the EMI tests of electronic
products. It can be used to test the magnetic field strength and magnetic field coupling
channels on the surface of the electronic components as well as the magnetic field
environment near the electronic module so as to quickly locate the interference source.
NFP-3 includes four models (NFP-3-P1, NFP-3-P2, NFP-3-P3 and NFP-3-P4).
Measurement Connections
The connection mode of NFP-3 and spectrum analyzer is as shown in the figure below.

Connect the spectrum analyzer
Connect the SMB (M) terminal of NFP-3 and the BNC (F) terminal of the N-BNC
adaptor respectively via the BNC-SMB RF cable; connect the N (M) terminal of the
N-BNC adaptor to the RF input terminal of the spectrum analyzer.
Connect the device under test
NFP-3 is used to perform short-distance noncontact measurement on the device
under test. Pay attention to the direction of the probe during measuring.
Typical Applications
Locate the EMI radiation interference source.
Determine the frequency and relative strength of the spectral component of the
interference source.
