Abstract
Electronic devices such as hybrid integrated circuits such as those having test points spaced less than 1250 .mu.m are advantageously evaluated utilizing a two-probe process. In this process the probes are moved between test points in a pattern that reduces movement distance without concern for any ordering imposed by the nets themselves or the test to be made. Additionally, the test is made so that the movement time is the limiting factor.
