Abstract:
1. An analog/digital characteristics testing device comprising: a plurality of measurement circuits for measuring an analog/digital characteristic of one or more ICs to be tested in accordance with a test condition data; and a setting unit for setting a different test condition data to each measurement circuits; and wherein the setting unit comprises: a test condition outputting circuit for outputting the test condition data in order; a counting circuit for counting the number of the test condition data outputted from the test condition outputting circuit; and a specifying circuit for specifying the measurement circuit in which the test condition data is written, in accordance with a counter value of the counting circuit; and when an initial test condition data is outputted from the test condition outputting circuit, the specifying circuit specifies all of the measurement circuits as a circuit in which the initial test condition data is written, and when a counter value counted by the counting circuit is equivalent to the number of the measurement circuit, the specifying circuit specifies the measurement circuits where the test condition data written to each measurement circuit is different from one another, at a point when the test condition outputting circuit finishes outputting the test condition data.
