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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Test apparatus","description":"A judgment unit judges the pass/fail of DUTs.
