A chip tester for testing at least two devices under test connected to the chip tester has a timing calculator for generating a timing information for the channels of the chip tester. The timing calculator is adapted to obtain a propagation delay difference information describing a difference between, on the one hand, a propagation delay from the first channel port of the chip tester to the first terminal of the first device under test and, on the other hand, a propagation delay from the first channel port of the chip tester to the second terminal of the second device under test. The timing calculator is adapted to provide a timing information for a second channel of the chip tester connected to the first device under test or to the second device under test on the basis of the propagation delay difference information. The channel module configurator is adapted to configure the second channel of the chip tester on the basis of the timing information.
