  2. LCR meter - Wikipedia

    en.wikipedia.org/wiki/LCR_meter

    An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

  3. Electronic test equipment - Wikipedia

    en.wikipedia.org/wiki/Electronic_test_equipment

    The addition of a high-speed switching system to a test system's configuration allows for faster, more cost-effective testing of multiple devices, and is designed to reduce both test errors and costs. Designing a test system's switching configuration requires an understanding of the signals to be switched and the tests to be performed, as well ...

  4. Power-off testing - Wikipedia

    en.wikipedia.org/wiki/Power-off_testing

    When the PCA can be further damaged by applying power it is necessary to use power off test techniques to safely examine it. Power off testing includes analog signature analysis, ohmmeter, LCR Meter and optical inspection. This type of testing also lends itself well to troubleshooting circuit boards without the aid of supporting documentation ...

  5. Impedance analyzer - Wikipedia

    en.wikipedia.org/wiki/Impedance_analyzer

    An impedance analyzer is a type of electronic test equipment used to measure complex electrical impedance as a function of test frequency.. Impedance is an important parameter used to characterize electronic components, electronic circuits, and the materials used to make components.

    Solid thermometer principle: relation between temperature and length of a solid (coefficient of thermal expansion). Bimetallic strip; Thermistors principle: relation between temperature and electrical resistance of ceramics or polymers, range: from about 0.01 to 2,000 kelvins (−273.14 to 1,700 °C)

  7. Four-terminal sensing - Wikipedia

    en.wikipedia.org/wiki/Four-terminal_sensing

    Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

  8. Spectrum analyzer - Wikipedia

    en.wikipedia.org/wiki/Spectrum_analyzer

    A spectrum analyzer is used to determine whether a wireless transmitter is working according to defined standards for purity of emissions. Output signals at frequencies other than the intended communications frequency appear as vertical lines (pips) on the display.
