  2. Cable tester - Wikipedia

    en.wikipedia.org/wiki/Cable_tester

    A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable. More advanced cable testers can measure the ...

    The delay skew test is used to find the difference in propagation delay between the fastest and slowest set of wire pairs. An ideal skew is between 25 and 50 nanoseconds over a 100-meter cable. The lower this skew the better; less than 25 ns is excellent, but 45 to 50 ns is marginal.

  4. Attenuation-to-crosstalk ratio - Wikipedia

    en.wikipedia.org/wiki/Attenuation-to-crosstalk_ratio

    Attenuation-to-crosstalk ratio (ACR) is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. [1] AcR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs. [ 2 ]

    en.wikipedia.org/wiki/Y.1564

    ITU-T Y.1564 is designed to serve as a network service level agreement (SLA) validation tool, ensuring that a service meets its guaranteed performance settings in a controlled test time, to ensure that all services carried by the network meet their SLA objectives at their maximum committed rate, and to perform medium- and long-term service testing, confirming that network elements can properly ...

    en.wikipedia.org/wiki/Networking_cable

    Networking cable is a piece of networking hardware used to connect one network device to other network devices or to connect two or more computers to share devices such as printers or scanners. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's topology ...

    Within months the Vestron release had sold 1 million copies, making it at the time the biggest-selling home-video release ever. Sadly, like so many other things in Jackson's life, "Thriller" was ...

  8. In-circuit testing - Wikipedia

    en.wikipedia.org/wiki/In-circuit_testing

    While in-circuit test is a very powerful tool for testing PCBs, it has these limitations: Parallel components can often only be tested as one component if the components are of the same type (i.e. two resistors); though different components in parallel may be testable using a sequence of different tests - e.g. a DC voltage measurement versus a measurement of AC injection current at a node.
