摘要： PROBLEM TO BE SOLVED: To resolve a problem of the fact that a resistive probe for verifying data links is of minor benefit, and not only may adversely affect links to be tested, but also may lead to difficulty to arrange individual resistors.
SOLUTION: Component-less termination for electromagnetic couplers used in high speed/frequency differential signaling is described. In one embodiment, the apparatus includes a first signal line and a second signal line forming a differential pair, a first electromagnetic coupler to provide sampled electromagnetic signals from the first signal line, and a second electromagnetic coupler to provide sampled electromagnetic signals from the second signal line, wherein the first electromagnetic coupler has a far end short-circuited and wherein the second electromagnetic coupler has a far end open-circuited.
