Abstract
Disclosed are an apparatus and method preferably for testing personal computer (PC) bus transmission line characteristics. The apparatus comprises: (1) a plurality of transmission line segments having different physical dimensions, each of the plurality of segments having a different electrical effect on signals transmitted thereon and (2) a switching circuit capable of coupling successive ones of the plurality of segments to an external conductor, an electrical characteristic of the external conductor affected by the coupling of the successive ones of the plurality of segments thereto, the apparatus permitting signals to pass through the external conductor and a selected one of the plurality of segments via the switching circuit. The apparatus allows a determination of a susceptibility of the external conductor to changes in transmission line electrical characteristics brought about by various possible combinations of peripheral expansion bus cards.
