    Abstract: Signal transit times on printed circuit boards which are equipped with all the passive components but without any active components can be determined using automatic standard test equipment composed of a standard test unit and a performance board with fittings attached thereto. In that first, using a standard routine of the test unit, a transit time is measured on the performance board from the CIF connector as far as the fitting, then a printed circuit board is plugged into the fitting location determined for it and then the sum transit time of the CIF connector is measured as far as the landing pad on the printed circuit board. By forming differences between the two measured values, the transit times on a printed circuit board can be measured with a high degree of precision with the automatic standard test equipment used in standard module testing technology.
