  2. Network analyzer (electrical) - Wikipedia

    en.wikipedia.org/wiki/Network_analyzer_(electrical)

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

    Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .

  4. Copper cable certification - Wikipedia

    en.wikipedia.org/wiki/Copper_cable_certification

    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.

  5. Optical time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Optical_time-domain...

    It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected back from points along ...

  6. Punch down tool - Wikipedia

    en.wikipedia.org/wiki/Punch_down_tool

    A punch down tool, punchdown tool, IDC tool, or a Krone tool (named after the Krone LSA-PLUS connector), is a small hand tool used by telecommunication and network technicians. It is used for inserting wire into insulation-displacement connectors on punch down blocks , patch panels , keystone modules , and surface mount boxes (also known as ...

  7. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    A multimeter can use many different test probes to connect to the circuit or device under test. Crocodile clips, retractable hook clips, and pointed probes are the three most common types. Tweezer probes are used for closely spaced test points, as for instance surface-mount devices. The connectors are attached to flexible, well insulated leads ...

  8. ANSI/TIA-568 - Wikipedia

    en.wikipedia.org/wiki/ANSI/TIA-568

    ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is Commercial Building Telecommunications Cabling Standard and is published by the Telecommunications Industry Association (TIA), a body accredited by the American National Standards Institute (ANSI).

  9. Cable tester - Wikipedia

    en.wikipedia.org/wiki/Cable_tester

    A simple tester for BNC and twisted pair cabling. 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 ...
