Hi Jay,
To load an S2P (Touchstone) file and access a single row in MATLAB, you can use the read function from the RF Toolbox. Here's a basic outline of how you can achieve this:
% Load the S2P file
s2p_data = read(rfdata.data, 'your_file.s2p');
% Access a single row (for example, row 1)
row_index = 1;
frequency = s2p_data.Frequencies;
s11 = s2p_data.S11(:, row_index); % Assuming you want to access S11
s12 = s2p_data.S12(:, row_index); % Assuming you want to access S12
% Similarly, you can access other parameters such as S21, S22, etc.
% Plot S11
plot(frequency, 20*log10(abs(s11)));
xlabel('Frequency (Hz)');
ylabel('S11 Magnitude (dB)');
title('S11 Parameter');
In this example, ‘read’ is used to load the S2P file, and then you can access a single row of the S-parameter data (S11, S12, etc.) by specifying the row index. After that, you can plot the S-parameter data or perform any other operations as needed.
Make sure you have the RF Toolbox installed to use the read function for S2P files in MATLAB.
Hope this helps!
