2. 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 ...

3. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   If a pure resistive load is placed on the output of the reflectometer and a step signal is applied, a step signal is observed on the display, and its height is a function of the resistance. The magnitude of the step produced by the resistive load may be expressed as a fraction of the input signal as given by:

4. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

5. 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 ...

6. 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 ...

7. Wi-Fi over Coax - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_over_Coax

   As expressed by the minimum acceptable received signal strength indication (RSSI) for the client device, maximum range via Wi-Fi over coax varies based on transmit power of the access point radio chain, the wireless LAN (WLAN) frequency or frequencies being transmitted, the type and length of the cabling run, assembly loss caused by the ...
