  2. Automatic test switching - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_switching

    Multiplexer; Like a scan configuration, multiplex switching can be used to connect one instrument to multiple devices (1:N) or multiple instruments to a single device (N:1), but it offers much more flexibility than the scanner configuration because it permits multiple simultaneous connections and both sequential and non-sequential switch closures.

DuinoBot v1.x [89] ATmega32U4 RobotGroup Argentina [90] Arduino fully compatible board, with integrated power supply and controllers designed for robotics. Compatible as well with the system "Multiplo" eJackino [91] Kit by CQ publisher in Japan.

  4. RF switch - Wikipedia

    en.wikipedia.org/wiki/RF_switch

    An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF ( radio frequency ) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT).

  5. Charlieplexing - Wikipedia

    en.wikipedia.org/wiki/Charlieplexing

    A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.

  7. RF switch matrix - Wikipedia

    en.wikipedia.org/wiki/RF_Switch_Matrix

    First, the switch matrix receives the data bus signals, then provides the proper switching and signal conditioning for the signals before feeding the signals to the test and measurement instruments. This custom switch matrix would employ 14 EM switches and a number of different signal conditioners including: power splitters, amplifiers, mixers ...

  8. Multiplexer - Wikipedia

    en.wikipedia.org/wiki/Multiplexer

    An electronic multiplexer can be considered as a multiple-input, single-output switch, and a demultiplexer as a single-input, multiple-output switch. [3] The schematic symbol for a multiplexer is an isosceles trapezoid with the longer parallel side containing the input pins and the short parallel side containing the output pin. [4]

  9. Three-state logic - Wikipedia

    en.wikipedia.org/wiki/Three-state_logic

    The basic concept of the third state, high impedance (Hi-Z), is to effectively remove the device's influence from the rest of the circuit. If more than one device is electrically connected to another device, putting an output into the Hi-Z state is often used to prevent short circuits, or one device driving high (logical 1) against another device driving low (logical 0).
