Abstract
A Device Under Test ('DUT') is monitored to determine when a test stops due to failure, completion, or otherwise. A series of signal stimulus in the form of a maintain active signal are applied to the DUT after the test has stopped. This protects devices that need continuous functional stimulus while connected to a power source. Upon the resumption of the test, the maintain active signal stimulus is synchronously replaced with an input test signal stimulus.
