METHOD for MEASURING COMMON MODE CHOKE IMPEDANCE


 

Those interested in more detail on my last post will find this article informative. The graphs at the end show what should be expected when making measurements of characteristic impedance of coaxial cables.


 

Hi Roger

Thanks , I re do the measure of my 25m of RG213 at 100Mhz (Span 5Mhz ) by this cicle methode see illustration below with graphical renormalized Z0 to center impedances circle around center smith shart.
