LISN Construction - What is inside of a LISN and why the DUT sees a 50 ohm impedance only
In one of our previous videos, we explained the purpose of using a LISN (Line Impedance Stabilisation Network) and how it functions. In this video we open one up, look inside and see why the load sees 50 ohms only. We then measure the impedance of the LISN in the lab with a Bode100 and show that at high frequencies LISN impedance is indeed 50 ohms.
