STEVAL-IFP015V2 CMTI test method

[SThcraeser]

Hello,

I noticed that the ISO8200B datasheet specifies CMTI (Common Mode Transient Immunity) performance.

However, I would like to know how to actually test or evaluate the CMTI of the ISO8200B using the STEVAL-IFP015V2 evaluation board.
Are there any recommended procedures or application notes for performing a CMTI test with this board?
If possible, could you provide some guidance or reference materials?

Thank you very much for your support.

Welcome @SThcraeser, to the community!

In principle, you could measure the CMTI with the board, the only question is how useful the results will be, because the STEVAL-IFP015V2 is intended for the development of your own device and not for such measurements, also because it contains external devices (capacitors, resistors, TVS, etc) at the inputs and outputs of the ISO8200B.

In addition, the measurement setup involves a number of challenges: very fast measurement technology, extremely steep pulse edges at the inputs, measurement on the isolated side, etc. You can find suggestions for such measurements using your favourite search engine and search terms such as "+measuring +cmti".

Hope that helps?
