Evaluating Clip-On Ferrite Beads with your nanoVNA (075)

We all have them somewhere ... that clip-on ferrite bead that we bought, was given, scavenged or found. We know absolutely nothing about it. What is it good for? How do I measure it? It's purpose is to increase the inductive reactance of any conductor it is clipped on to. This, then, makes the conductor act like a higher impedance to R.F. and the like to prevent noise or interference from traveling down the wire. But not all ferrite beads and materials are created equal. Not all will do what you might want to do. Which one of those junk box ferrites is the best for your needs? In this video I will show you a very basic method of evaluating the performance of a ferrite bead using a nanoVNA. While the totally ideal method keeps the wire in the fixture as short as possible, this is a way to compare these clip-ons which can be quite large in size. ======================================= Time Markers for Your Convenience ---------------------------- 00:05 Introductory Comments 01:16 Setup 01:18 The Fixture 02:14 The nanoVNA 04:12 The Measurement 06:50 The Comparison 08:58 Final Comments and Tootle-Oots
