If you want simulate S-parameters in LTspice you should use “.net” command
Set V2 source with series impedance 50 ohm and terminate circuit with R2=50 ohm and put command: .netI(R2) V2
Of course, you can see S, Y and Z matrix
In engineer’s work or hobbyst we must use computers and tools. We need dedicated programs to simulate, design or do equations for projects. In this article I will describe some electronics programs. This article is good for beginners. Continue reading Programs for electronics
