S-Parameter I/O and Visualization

Load, inspect, visualize, and export S-parameters using the sparameters object and RF Toolbox plotting functions.

When to Use

• Loading Touchstone files (.s1p, .s2p, .s4p, .snp) into MATLAB
• Extracting S-parameter values with rfparam
• Plotting S-parameters with rfplot or smithplot
• Computing group delay from S-parameter data
• Interpolating S-parameters to a new frequency grid with rfinterp1
• Changing reference impedance with newref
• Exporting S-parameters to Touchstone format with rfwrite

When NOT to Use
