  • Method and apparatus for measuring AC shield continuity for shielded twisted pair structured datacomm cable link
    Patent number: 8570049
    Abstract: AC shield continuity for shielded twisted pair structured datacomm cable is determined by testing the cable, driven in a common mode, over a range of frequencies, to determine presence and location of shield breaks. DC ground path generated false results are thereby avoided.
    Type: Grant
    Filed: December 9, 2010
    Date of Patent: October 29, 2013
    Assignee: Fluke Corporation
    Inventors: Jeffrey Sandsmark Bottman, Jun Ho Yi
