Abstract: A computer controlled circuit tester is provided for applying predetermined signals to, or taking signals from, individual ones of an array of pins to which the circuit to be tested is connected. Identifier characters are decoded to determine tests to be performed in accordance with associated data characters. Provision is made for blocks of pins making up the array to be successively addressed automatically for energisation according to the data characters and also, using a particular identifier, for selecting any desired block of pins. Similar techniques are used to select desired delays in actions specified relative to the pins.
