Patent ID: 8049513

Claim:
A method for the adjustment of an output signal that is produced by a device under test and that is dependent on a physical input variable, wherein the device under test has adjustment means that influence the output signal and that is put in at least two adjustment states, comprising the following steps: a) positioning the device under test at a first test device, in which a physical disturbance variable has a predetermined disturbance variable value and the input variable has a known input variable value, b) acquiring at least one measured value for the output signal, c) changing the adjustment state, d) acquiring at least one further measured value for the output signal, e) positioning the device under test at a further test device, at which the disturbance variable has a predetermined further disturbance variable value and the input variable has the input variable value, f) acquiring at least one further measured value for the output signal, g) changing the adjustment state, h) acquiring at least one further measured value for the output signal, i) for each adjustment state, comparing the measured values acquired at the test devices and determining a first adjustment state in which the correlation between the measured values is larger than in a second adjustment state, j) adjusting the first adjustment state in the event that the adjustment state of the device under test deviates from the first adjustment state.
