I am completely new to this. I have a .s2p file, and i need to plot them into a smith chart. there are 10006 values, and i do not know how to do this. Can someone please tell me how to, and give me the code. i need a little bit of coaching as i have never done this before so i need a little guidance. please please help. Thanks in advance!
 

If you have RF Toobox, do the following.
]
Code: 
measured_data=read(rfdata.data, 'f150m_a.s2p');

s11_hid = smith(measured_data, 'S11');
set(s11_hid, 'color', 'r', 'LineWidth', 2)
hold on

s22_hid = smith(measured_data, 'S22');
set(s22_hid, 'color', 'b', 'LineWidth', 2)

There are many free tools for touchstone/SYZ viewing. Teledyne Lecroy has an excellent viewer SI Studio. It is freeware.
