2 How to Power Analog Switches

To power an analog switch on an ATE board, any power supply innate to the tester that can support the required voltage can be used. Below are the most common options available on an ATE board.

  • An instrument on the tester (for example, analog sources and supplies)
  • Power rails of the tester
