4-Channel FRA analyzer

Hi All,

Its been rather quite in the last few days/week in this forum.

So, today I want to share my new 4-Ch FRA analyzer which is a modification of my original 2-Ch FRA analyzer that I posted a long while back. My original background for this modification is to accomodate my need to get freq domain response from more than two measurement node all at once, e.g. to obtain controller, system, and feedback bode plot all at once which I needed for my own internal project.

Welcome to review this analyzer and download it from my Github repo:
