A test and measurement device, including a first input structured to receive a first voltage from a first conductor of a first triaxial cable, a second input structured to receive a second voltage from a second conductor of the first triaxial cable or a second triaxial cable, circuitry configured to change modes based on the first voltage and the second voltage; and an output structured to output a signal.

A device may utilize a cable that includes connectors and conductors to transfer signals, electrical power, or both. Some cable failures result in an inability to transfer signals. Other failures may result from different cables being used at different times, resulting in a mismatch in which the cable is rated to transfer less power than what could otherwise be delivered by the power source. Parameters, such as cable impedance, transmitter gain, signal conditioning, and so forth that are associated with use of the cable are monitored at different times. If the values of these parameters from one time to another exceed a threshold value, a fault in the cable is determined. A notification about the impending or actual failure of the cable may be presented, and a suitable cable may be recommended for purchase. For example, a hyperlink may be provided to allow for purchase of the suitable cable.

A method, a structure, and a computer system for a modular sensing unit. The structure comprises a sensor module, a power cable ribbon, and a component module, wherein the component module is in communication with and detachable from the sensor module via the power cable ribbon.

A composite cable includes a twisted assembly including a pair of first single core wires and first and second multicore wires that are each arranged in one or the other of regions facing each other across a center plane passing through the central axes of the pair of first single core wires, include an electric wire with a solid (non-hollowed) structure including a first or second twisted pair wire formed by twisting a pair of second or third single core wires with a smaller cross-sectional area than the first single core wire and a first or second inner sheath covering the first or second twisted pair wire so as to fill a space between the pair of second or third single core wires, and have an outer diameter that is not less than 70% and not more than 160% of the outer diameter of the first single core wire.

A flex flat cable (FFC) structure includes metallic transmission wires arranged in parallel, first insulating jackets, and second insulating jacket. The metallic transmission wires includes one or more power wires and signal wires. The power wire is configured to transmit power. The signal wires are configured to transmit a data signal.

A composite cable that enables to easily restrain falling-off of separator dust at the time of peeling off a sheath, in comparison with composite cables in the conventional art. The composite cable includes a plurality of wires, a separator that covers the outer circumference of the plurality of wires all together, a sheath that covers the outer circumference of the separator, and an inclusion that is interposed between the separator and the sheath. The separator has a base layer composed of a polymer and an adhesive layer formed on the surface of the base layer on the inclusion side. In the composite cable, the adhesive layer is adhered to the inclusion.
