  2. Two-tone testing - Wikipedia

    en.wikipedia.org/wiki/Two-tone_testing

    Two signal generators, set to two different frequencies F1 and F2, are fed into a power combiner through circulators. The combiner needs to have good isolation to prevent the signal from one generator being sent to the output of the other. If this happens, intermodulation can occur in the non-linear parts of the generator internal circuit.

  3. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    The main difference between the effects of single and multiple scattering is that single scattering can usually be treated as a random phenomenon, whereas multiple scattering, somewhat counterintuitively, can be modeled as a more deterministic process because the combined results of a large number of scattering events tend to average out.

  4. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    Rutherford computes the probability of single scattering from a compact charge and demonstrates that it is 3 times larger than Thomson's multiple scattering probability. Rutherford completes his analysis including the effects of density and foil thickness, then concludes that thin foils are governed by single scattering, not multiple scattering.

  5. Load bank - Wikipedia

    en.wikipedia.org/wiki/Load_bank

    A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...

  6. Stirling radioisotope generator - Wikipedia

    en.wikipedia.org/.../Stirling_radioisotope_generator

    A later engine of this size, the Component Test Power Converter (CTPC), used a "Starfish" heat-pipe heater head, instead of the pumped-loop used by the SPDE. In the 1992-93 time period, this work was stopped due to the termination of the related SP-100 nuclear power system work and NASA's new emphasis on "better, faster, cheaper" systems and ...

  7. Engine–generator - Wikipedia

    en.wikipedia.org/wiki/Enginegenerator

    In addition to the engine and generator, enginegenerators generally include a fuel supply, a constant engine speed regulator (governor) in diesel and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may ...

  8. Automatic test equipment - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_equipment

    Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.

  9. Automatic test switching - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_switching

    Automatic test system switching test equipment allows for high-speed testing of a device or devices in a test situation, where strict sequences and combinations of switching must be observed. By automating the process in this way, the possibility of test errors and inaccuracies is minimized, and only systematic errors would generally be ...
