PURPOSE:To improve the reliability of DUT tests by making complicated control for signal generation and measurements compatible with their time management so that the DUT tests can be performed under a condition which is very close to an actual operating condition. CONSTITUTION:Slave subsystems 11, 12,... are operated under the control and management of a master subsystem 10. A control signal synchronizing means 3 synchronizes a control signal from the system 10 with master clocks MCLK 1 or 2 and outputs the synchronized control signal to each slave subsystem through a clock distributing means 4. When the control signal is outputted to each subsystem, a clock distributing means 5 is controlled so that the master clock of the same timing as that of the synchronized control signal can be inputted to each slave subsystem. Then each slave subsystem generates the operating timing of each slave subsystem by dividing the inputted master clock by a prescribed integer. |
