ABSTRACT:
The invention provides a test apparatus for testing a circuit unit (101) to be tested having a test system (100), a control bus (102) for transferring control data (106), an address bus (103) for transferring addressing data (107) and a data bus (104) for exchanging test data (108) between the test system (100) and the circuit unit (101) to be tested. A voltage generating device (200) connected between the test system (100) and the circuit unit (101) to be tested serves for generating a predeterminable operating voltage output signal (202, 202a-202n) for the voltage supply of the circuit unit (101) to be tested in a manner dependent on a control signal (211) that is provided by the test system (100) and fed via the control bus (102).
