A method for pulsed behavior modeling of a device under test (DUT) using steady state conditions is disclosed. The method includes providing an automated test system (ATS) programmed to capture at least one behavior of the DUT. The ATS then generates a DUT input power pulse that transitions from a predetermined steady state level to a predetermined pulse level and back to the predetermined steady state level. At least one behavior of the DUT is then captured by the ATS while the input power is at the predetermined pulse level. The ATS then steps the predetermined pulse level to a different predetermined pulse level, and the above steps are repeated until a range of predetermined pulse levels is swept. The ATS then steps the predetermined steady state level to a different steady state level, and the above steps are repeated until a range of predetermined steady state levels is swept.
