Part 3 of a series on using near-field probes for detecting EMI sources shows you how ... Broadband DC-DC converter noise can couple into PCB traces and wires, creating EMI problems. In Figure 5, the ...

An 18 mm H-Field ... These probes were designed using KiCad. The integrated calculator was used to compute RF transmission lines characteristics. For the ease of manufacturing purposes, all probes are ...

In addition to an oscilloscope, you will need high-performance probes and the ability to choose the optimum versions—including 10x passive, power-rail, near-field, current, and differential ...

Unlike normal current probes, B field probes allow for the non-intrusive measurement of current flowing through PCB traces and inductors by measuring the magnetic fields they generate. While non ...

This paper presents the effect of the inhomogeneous medium on the near-field generated over a grounded coplanar waveguide (GCPW) printed circuit board (PCB) and reports the field pattern over the GCPW ...

To find where on a PCB the emissions might originate, you might use a simple magnetic-field probe (see figure) connected to a spectrum analyzer. You then sweep the probe manually or with an automated ...

To find emissions on individual pins or PCB traces, use E-field probes that make direct contact with your circuit. Figure 1. Near-field probe sets may include three sizes of H-field loop probes and ...
