To provide a signal applying/signal measuring apparatus which does not have any extra equipment except a signal applying module, a signal measuring module, and computing equipment, and has its time synchronized even when the computing equipment is newly replaced with equipment improved in processing capability and processing speed to confirm the performance of the object electronic control equipment.
The signal applying/signal measuring apparatus includes the applying module which applies a signal to the electronic control equipment whose performance is to be confirmed, the measuring module which measures the signal, and the computing equipment which controls the applying module and the measuring module through a serial bus. The applying module, measuring module, and computing equipment have time broadcasting means, and the applying module and measuring module each synchronize time that it manages with the time that the computing equipment manages within a predetermined deviation, and also synchronize the time that it manages with time that the applying module or measuring module manages within a predetermined deviation.
