  • Method of determining settling time of a device under test
    Patent number: 5162744
    Abstract: Settling time of an electrical device under test in response to a step wave input voltage is determined by first establishing first and second output voltage levels which differ from a settled output voltage level by preestablished voltage differentials, and then determining the time after applying a step wave voltage to the device under test when the output voltage equals the first and second voltages. A voltage controlled oscillator is utilized in triggering the step wave voltage generator and in enabling a voltage comparator whereby the period of the voltage control oscillator is a measure of the settling time of the device under test.
