Featured Examples

De-Embedding S-Parameters

Extract the S-parameters of a Device Under Test (DUT). First, read a Touchstone® file into a sparameter object, second, calculate the S-parameters for the left and right pads, third, de-embed the S-parameters using the deembedsparams function and finally display the results.
