    s2p files

    got it. I opened one .s2p file with notepad. I admitted new parameters & resaved in notepad. Then changed the file extention to .s2p. The appcad recognises the file but RFSIM99 doesn't recognise it. The RFSIM99 recognise the original file but not created by me. The appcad recognises both the files.
    How to solve this problem?
