Rune, I found a very good use for the permeability function today. I have a ferrite core samples kit from Amidon that I acquired years ago. Somehow the 4 BN61-202 devices had become mixed with the 4 BN73-202 devices and I needed to know which was which. I ran the permeability curves on one and the curves didn't cross below 30 MHz so I assumed it was 61 material. The next test curves crossed at about 4 MHz so I assumed it was 73 material. So I was able to separate the 61 material from the 73 material in nothing flat. Thanks very much for this very useful enhancement.
