FesZ Electronics | EMC debugging - Near field Magnetic field probes @FesZElectronics | Uploaded July 2020 | Updated October 2024, 2 hours ago.
#81 In this video I continue looking at near field probing methods by analyzing Magnetic field probes. I start off by generating magnetic fields using a Helmholtz Coil and them I proceed to measure it using a selection of magnetic field probes. I analyze the main noise related issues and afterwards I proceed to look at a practical circuit, both with the magnetic field probe as well as the electric field probe.

#117 In this video I start testing the LISN to see just how good it is. I look at multiple things starting with output impedance then go for insertion loss, input impedance and input side filtration and finally look at inter-channel isolation or cross talk.
