  • Patent number: 9702929
    Abstract: A judgment unit judges the pass/fail of DUTs. A power supply circuit has changeable characteristics, and supplies a power supply signal to the DUTs. A condition setting unit performs a pilot test before a main test for the DUTs, and acquires a test condition to be used in the main test. The condition setting unit executes: (a) measuring a first device characteristic value for each of multiple pilot samples sampled from among the DUTs while emulating a power supply characteristic close to what is used in a user environment in which the DUT is actually used; (b) measuring a predetermined second device characteristic value for each of the multiple pilot sample devices while emulating a power supply characteristic close to what is used in a tester environment in which the main test is performed; and (c) determining the test condition based on the first and second device characteristic values.

  • Patent number: 9689922
    Abstract: A computer implemented process is described for testing multiple electronic devices under test (DUTs). A design test pattern or command/instruction is generated with an electronic design automation tool (EDA). The generated design test pattern and command/instruction is sent directly to an automated test equipment apparatus (ATE) over a UNIX or scripting language based, and/or a network based, communication pipeline. The ATE converts the sent design test pattern to an instance of the test pattern directly executable by the ATE. The ATE apparatus inputs test signals to each of the multiple electronic DUTs based on the executable test pattern. The ATE apparatus then receives, from each of the multiple electronic DUTs, a test result based on the input test signals. The ATE returns the received test result, and a report of an action responsive to the command/instruction to the EDA tool, which may then process the test results and report.

  • Patent number: 9647632
    Abstract: A preferred method for efficiently tuning RF ports while avoiding conventional labor intensive, step-by-step processes is disclosed. The method may use at least three tuning blocks (comprised of capacitors and inductors) in a series topology and at least three tuning blocks in a shunt topology. These tuning blocks will yield two circles that can be charted on the Smith chart. Those circles may then be centered along the centerline of the Smith chart to adjust for latency, and then expanded to adjust for the losses. Once those circles have been expanded, the circle (either series or shunt) that encompasses one the Smith chart reference circles is used and the traditional Smith chart methodology can be used to tune the RF port.
