Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A woven electrical cable for use with multiple probe systems, comprising: a plurality of resistive means, each connectable to a measuring instrument and a probe tip for carrying signals from a system under test and for damping out reflections, a plurality of conductive means, each associated with a particular resistive means, connectable to a reference voltage in the system under test and a reference in the measuring instrument for electrically shielding the resistive means, fabric means having a nonconductive nature for isolating each resistive means from the associated conductive means, for maintaining a relatively constant proximity of each resistive means to the associated conductive means, and for protecting all resistive means and all conductive means from physical impacts and abrasions and from electrical static discharge into all resistive means and all conductive means.
Claim 2
Dependent Claim
