ABSTRACT:
A test apparatus for testing such electrical circuit elements as components of printed circuit boards or integrated circuit chips includes a number of substantially indentical pin modules or units, one for each pin under test. The several modules are separately programmed by a CPU to provide a suitable state at the pin under test, i.e., excitation signal, read signal or impedance. Power to the unit under test is provided by the pin module.
