Patent ID: 7375508

Claim:
A device for calibration of a probe card and/or of a semi-conductor component test apparatus, comprising: a first connection, at which a calibration signal is applied; a second connection, configured for connection with the first connection at which the calibration signal, is emitted; a third connection, at which a further calibration signal, is applied; and a fourth connection, configured for connection with the third connection, at which the further calibration signal is emitted; wherein the device is configured such that, in a first setting of a probe card, a first contact of the probe card configured for connection with a reference driver channel contacts the first connection, and a second contact of the probe card configured for connection with a first comparator channel, contacts the second connection, and wherein the device is further configured such that, in a second setting of the probe card, the first contact of the probe card configured for connection with the reference driver channel, contacts the third connection, and a third contact of the probe card, configured for connection with a second comparator channel contacts the fourth connection.
