    The award is presented annually for outstanding contributions in electrical measurements, and is sponsored by Keithley Instruments and the IEEE Instrumentation and Measurement Society. [ 1 ] [ 2 ] The award is not to be confused with the similarly-named Joseph F. Keithley Award For Advances in Measurement Science of the American Physical ...

  3. Source measure unit - Wikipedia

    en.wikipedia.org/wiki/Source_measure_unit

    The source measure unit (SMU), or source-measurement unit, is an electronic instrument that is capable of both sourcing and measuring at the same time. It can precisely force voltage or current and simultaneously measure precise voltage and/or current. An SMU instrument can source and sink power in all four quadrants.

    Keithley Instruments is a measurement and instrument company headquartered in Solon, Ohio, that develops, manufactures, markets, and sells data acquisition products, as well as complete systems for high-volume production and assembly testing.

  5. Current-mode logic - Wikipedia

    en.wikipedia.org/wiki/Current-mode_logic

    Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data.. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.

    en.wikipedia.org/wiki/Current_source

    Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V. A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative ...

  8. Current limiting - Wikipedia

    en.wikipedia.org/wiki/Current_limiting

    Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device.

  9. GPS disciplined oscillator - Wikipedia

    en.wikipedia.org/wiki/GPS_disciplined_oscillator

    A GPS disciplined oscillator unit with a GPS antenna input, 10 MHz and 1 pulse-per-second (PPS) outputs, and an RS-232 interface.. A GPS clock, or GPS disciplined oscillator (GPSDO), is a combination of a GPS receiver and a high-quality, stable oscillator such as a quartz or rubidium oscillator whose output is controlled to agree with the signals broadcast by GPS or other GNSS satellites.
