Measure S-Parameter Data of Chebyshev Filter

Use the S-Parameter Testbench block to measure S-parameter data of a ninth-order Chebyshev Tee LC low-pass filter.

Set the parameters of the Filter block as shown in this image.

Set the parameters of the S-Parameter Testbench block to measure the S-parameters of the Chebyshev filter.

Run the simulation to yield the measured S-parameter data for the Chebyshev filter.

Note that due to the symmetry and reciprocity of the filter, the plots for S11 and S22 and S12 and S21 overlap each other. The results can be compared with the plot obtained from the Visualization tab of the Filter block.

In addition to viewing the results in the Spectrum Analyzer, you can export the result as an RF Toolbox™ S-parameter object or as a Touchstone® file for further processing.
