Patent ID: 7409615

Claim:
A test apparatus for testing a device under test, comprising: a driver for applying a test signal to the device under test; a comparator for comparing a result signal outputted by the device under test corresponding to the applied test signal with a predetermined reference voltage; and a setting voltage output section for setting the voltage of the test signal to a predetermined voltage value to cause the driver to terminate a transmission path of the result signal when the test apparatus reads from the device under test, further comprising: a first relay for switching whether the test apparatus is provided to the driver; a terminating circuit for terminating the transmission path of the result signal; a second relay for switching whether the transmission path of the result signal is terminated by the terminating circuit; and a relay control section for switchably control whether the first relay stops providing the test signal to the driver and the second relay causes the terminating circuit to terminate the transmission path of the result signal instead that the setting voltage output section causes the driver to terminate the transmission path of the result signal when the test apparatus reads from the device under test.
