Patent ID: 7143325

Claim:
Test device for testing circuit units to be tested, having: a) connecting units for connecting the circuit units to be tested to the test device; b) a test system, which (i) writes test data to the circuit units to be tested; (ii) reads out measurement data generated by the circuit units to be tested in a manner dependent on the test data written in; and (iii) compares the measurement data read out with defined expected data and provides test result data in a manner dependent on the comparison; and c) an output unit for outputting the test result data, characterized in that the test device further has: d) a determining unit for determining those of the measurement data which correspond for a predeterminable number of circuit units to be tested, and for defining the corresponding measurement data as the expected data; and e) comparison units for comparing the measurement data generated by the circuit units to be tested in a manner dependent on the test data written in with the expected data in order to obtain comparison data.
