S‐parameter measurements provide substantial information about the qualities of a DUT. In many cases, the transformation and formatting of these parameters is necessary to more readily understand the intrinsic attributes of the DUT. Some of these transformations are graphical in nature, such as plotting on a Smith chart; some are formatting such a group delay and SWR; and some are functional transformation such as time‐domain transforms. Some of the more important transformations are discussed next, with emphasis on some particularly interesting results.
