ABSTRACT:
A method and apparatus for automatic, programmed, in-circuit component testing and functional testing. A multi-mode measurement unit having an exciter circuit, computing circuit, and a converter circuit is provided for measuring electrical signals. The measurement unit is controlled by a program-commanded measurement unit controller. A plurality of device connection switches are provided for connecting, by a program-commanded switch controller, the computing circuit to selected nodes of a circuit under test. The switch controller and the measurement unit controller receive commands from a programmed processor which executes stored programs of instruction. The programs contain subroutines which correlate with commanded measurement parameters and sequences within the measurement unit.
