#242 In this video I look at some of the basic steps that need to be taken when verifying coaxial cable assemblies. After extended use, mainly connecting and disconnecting, cables can get damaged, so its important to periodically verify that they did not lose their proprieties. For this purpose I will look at both the simple electrical continuity verifications as well as the more complex frequency domain checks.

#127 In this video I try to improve on the original design of the LISN by addressing some of its issues and taking a more detailed look at the inter-channel isolation. Things dont turn out exactly as planned but some valuable insight can be observed nonetheless.

#114 In this video I look at the specifications and parameters behind a line impedance stabilization network, or LISN. I look at what is the purpose of the various components is and then take a closer look at how the values need to be chosen. Finally I build such a device.
