  • Thermal control
    Patent number: 9766287
    Abstract: An example test system includes: a heating mechanism; a cooling mechanism; an instrument module having one or more interfaces to receive signals from a device under test (DUT), where the instrument module includes one or more electrical components to affect the signals, where the instrument module is between the heating mechanism and the cooling mechanism, and where the heating mechanism and the cooling mechanism are each configured to operate to maintain the instrument module within a target temperature range.
    Type: Grant
    Filed: October 22, 2014
    Date of Patent: September 19, 2017
    Assignee: Teradyne, Inc.
    Inventors: John Kenji Narasaki, Kevin A. Thompson

  • Liquid cooling during testing
    Patent number: 8736288
    Abstract: A system includes electronics for testing a device, a reservoir to store coolant, where the reservoir includes a bellows that is compressible, a pump system to move coolant out of the reservoir to cool the electronics, and means to compress the bellows and thereby pressurize the coolant stored in the reservoir so that the coolant remains substantially flush with an interface to the pump system.

  • Electronic Detection of Signatures
    Publication number: 20110316545
    Abstract: A method is described for retrieving, by a test system, a formation profile associated with the storage cell, the formation profile comprising one or more formation segments, with a formation segment comprising an action to be performed upon a detection of a signature value; measuring, by the test system, a value of a parameter of the formation segment; detecting, based on a comparison between the value of the parameter and one or more signatures associated with the formation segment, that the value of the parameter comprises the signature value; and performing the action specified in the formation segment.
