Abstract
A test device (1) for testing a module (2) for a data carrier intended for contactless communication includes a carrier signal generator (14) which is arranged to generate a carrier signal (CS) whereby a test signal (TS) can be generated, a conductive connection being provided between the carrier signal generator (14) and a module (2) to be tested, which connection includes an impedance (31), preferably being a series resistor (31), which is connected directly ahead of a module terminal (5) of the module (2) to be tested, the test device (1) being provided with at least one detection device (34, 35) for determining an analog characteristic value (C, m) of a module (2) to be tested while utilizing the test signal (TS) appearing on an impedance terminal (32) of the impedance (31).
