Hello.
I have a wide asortment of different unknown toroidal cores and in an attempt to find suitible methods to characterise these i've really lost my way.
I've read about the subject a lot from all sources i could find around the internet but have now ended up feeling less knowledgeable than when i started.
My intension was to create a work list that i could follow to get the most accurate and useful parameters of a core down on paper and when free time came around go through all my cores and document said results in a kind of index.
Avalible equipment:
2 channel 60MHz DSO
2 channel 20MHz, 100MSa/s arbitrary waveform generator
DMM
Solder iron, component asortment, yada yada yada.
So far i've measured(with caliper) hight, inner diameter, outer diameter and from there calculated magnetic path -area and length.
But now i am drawing a blank.
Where should i go from here and which properties can i realistically measure?
Ex: initial- relative- absolute permeabilty, inductance factor, saturation limit...
I could really use some guidence.
