A method for testing a circuit (20) designed for contactless data communication, which comprises an antenna (22) and an electronic component (24) coupled to the antenna (22), therefore comprises the following steps: generation (S1) of a magnetic alternating field of a field strength and arrangement (S2) of the circuit (20) within the alternating field range. The electronic circuit (20) is then excited by means of an energy pulse (S3). In a further step, an oscillation of the circuit (20) in response to the excitation of the circuit by the energy pulse is detected (S4). The detected oscillation of the circuit (20) is finally evaluated (S5), in particular with regard to a self-resonant frequency of the circuit (20). |
