ABSTRACT:
A response expander circuit provides to a unit under test a number of response channels which is greater than the number of response channels provided by a basic test control unit. The increased response channel count is accomplished by separating the channels available to the unit under test into two separate patterns, and time division multiplexing the two patterns so that the two patterns are sequentially supplied to the basic test control unit for processing.
