摘要： A test apparatus tests a device under test. The test apparatus includes a period generator that generates a rate signal determining a test period according to an operating period of the device under test, a phase comparing section that inputs an operational clock signal for the device under test generated from the device under test and detects a phase difference between the operational clock signal and the rate signal using the rate signal as a standard, a test signal generating section that generates a test signal to be supplied to the device under test in synchronization with the rate signal, a delaying section that delays the test signal in accordance with the phase difference to substantially synchronize the delayed signal with the operational clock signal, and a test signal supplying section that supplies the delayed test signal to the device under test.

摘要： In a control method and control device for an engine, in order to prevent torque control precision from deteriorating while performing an ignition retard control in a variable valve engine, when a torque down control is carried out by using the ignition retard, combustion duration is calculated in consideration of valve timing or an engine rpm for each driving state, and a characteristic of a reference ignition timing efficiency curve is corrected on the basis of a difference between the combustion duration and a combustion duration reference value which is set in advance.
