POWER SUPPLY, AUTOMATED TEST EQUIPMENT, METHOD FOR OPERATING A POWER SUPPLY, METHOD FOR OPERATING AN AUTOMATED TEST EQUIPMENT AND COMPUTER PROGRAM USING A VOLTAGE VARIATION

摘要

A power supply is configured to perform an at least partial compensation of a voltage variation caused by a load change using a voltage variation compensation mechanism which is triggered in response to an expected load change. An Automated test equipment for testing a device under test comprises a power supply, which is configured to supply the device under test. The automated test equipment comprises a pattern generator configured to provide one or more stimulus signals for the device under test. The power supply is configured to perform an at least partial compensation of a voltage variation caused by a load change using a voltage variation compensation mechanism which is activated in synchronism with one or more of the stimulus signals and/or in response to one or more response data signals from the device under test. Corresponding methods and a computer program are also described.
