Abstract
A circuit is provided wherein a test pulse is provided to a device under test. A module allows the test pulse to pass through to the device under test. The module blocks a reflected pulse from passing through to the device under test when the reflected pulse has an opposite polarity from the polarity of the test pulse. In some cases, the reflected pulse may be detrimental to the device under test if it is not prevented from reaching the device under test. In one embodiment, when a second reflected test pulse is traveling away from the device under test, the module allows the second reflected test pulse to pass through.
