Test device for testing a module for a data carrier intended for contactless communication

A method of manufacturing a module (2) which is constructed for use in conjunction with a data carrier intended for contactless communication and includes an integrated component (4), two module terminals (5, 6) for connection to two transmission means terminals, the module (2) being subjected to a test operation by means of a test device (1) which includes two test terminals (12, 13),

• in which each module terminal (5, 6) of the module (2) is brought into contact with a test terminal (12, 13) of the test device (1), and
• in which a carrier signal (CS) is generated by means of a carrier signal generator (14) of the test device (1), and
• in which a test signal (TS) which corresponds to the carrier signal (CS) output by the carrier signal generator (14) is applied to the at least one test terminal (12) via a signal path (33) which is situated between the carrier signal generator (14) and at least one test terminal (12), and
• in which the test signal (TS) is load modulated by means of load modulation means included in the integrated component (4) of this module (2), when module terminals (5, 6) of the module (2) are in contact with the test terminals (12, 13), characterized in that
• the test signal (TS) corresponding to the carrier signal (CS) is applied to the at least one test terminal (12) via a signal path (33) which is constructed so as to be conductive and includes an impedance (31) connected directly ahead of the at least one test terminal (12), and
• that, utilizing at least one detection device (34, 35), connected at least to one test terminal (12), of the test device (1), an analog characteristic value (C, m) of the module (2) which is in contact with the test terminals (12, 13) by way of its module terminals (5, 6) is detected while utilizing the test signal (TS) that can be applied to the at least one test terminal (12).

A method of simultaneously testing a digital functionality and determining an analog characteristic value of a module intended for use in a data carrier having contactless communication capability, the module having two module terminals for connection to transmission terminals of the data carrier, comprising the steps of:

• contacting the two module terminals to respective test terminals of a test device;
• generating a carrier modulated test signal in the test device;
• applying the carrier modulated test signal to at least one of the test terminals, the carrier modulated test signal testing a digital functionality of the module without contactlessly communicating the carrier modulation test signal to the module;
• and
• connecting a detection device to at least one of the test terminals for simultaneously measuring an analog characteristic of the module utilizing the same applied carrier modulated test signal.
