The invention provides a testing apparatus of an intelligent card module for a television system. The testing apparatus is composed of a control unit, a first interface, a second interface, a signal line group, a switching module and an impedance adjusting module. The apparatus is connected with an intelligent card by the first interface and is connected with a television system by the second interface. The control unit is used for generating a switching signal, an impedance adjusting signal, and an operating signal; the switching signal is used for controlling the switching module to control a signal line conduction state of the signal line group; the impedance adjusting signal is used for controlling the impedance adjusting module to adjust the impedances of the signal lines in the signal line group; and the operating signal is transmitted to the television system by the second interface. Therefore, the television system can use the testing apparatus to carry out data access on the intelligent card, thereby completing correlated testing items of the intelligent card.
