A test apparatus for testing a device under test 15 is provided. The test apparatus includes a driver 122 for applying a test signal to the device under test, a comparator 128 for comparing a result signal outputted by the device under test 15 corresponding to the applied test signal with a predetermined reference voltage and a setting voltage output section 110 for setting the voltage of the test signal to a predetermined voltage value to cause the driver 122 to terminate the transmission path ...

A test apparatus to test a device under test (DUT) to which a reference voltage of a predetermined high voltage is supplied is provided. The test apparatus includes a reference voltage applying section that applies the reference voltage to the DUT, wherein the reference voltage defines a voltage level that is to be possessed by an output signal output from the DUT when the output signal indicates a predetermined logical value, a voltage level detecting section that detects a voltage level of the...

A test method sets a write value to a scan flip-flop for setting a value to a memory to be tested. It then performs a series of shift operation in scan paths until setting of a read value is completed. During the shift operation, a value for refresh operation is added to the value passing through the flip-flop for setting a value to the memory to be tested.

Change in power supply voltage supplied to a device under test is controlled. There is provided a test apparatus for testing a device under test, the test apparatus including: a reference voltage supply section for supplying a reference voltage; a field effect transistor provided between a positive side terminal and a negative side terminal of the reference voltage supply section, so that a drain terminal and a source terminal of the field effect transistor are in parallel connection with the de...

There is provided a testing device including: a first signal comparator operable to acquire a value of an output pattern based on a result that is obtained by comparing a voltage of an output signal and a first threshold value voltage in a first strobe timing, in order to acquire a first output pattern sequence; a second signal comparator operable to acquire a value of an output pattern based on a result that is obtained by comparing a voltage of an output signal and a second threshold value vol...

A test apparatus for testing switching speed of a circuit, which includes a pre-stage logic element outputting a first or second level voltage and a post-stage logic element to which the output signal of the pre-stage logic element is input, is provided, wherein the post-stage logic element includes the post-stage FET, a gate terminal of which the output signal is input to, for outputting a different level of voltage according to the case that the output signal voltage is higher or lower than a ...

A test apparatus includes: an instruction execution unit for sequentially executing instructions in a test program for a DUT in each instruction cycle; a default pattern memory for storing default pattern sequence to be associated with default pattern identification information for identifying that default pattern sequence; a test pattern memory for storing test pattern sequence output in an instruction cycle period for executing that instruction or the default pattern identification information...

A modified RAST test is used to determine a safe initial immunotherapy dosage. The dosage is inversely proportional to the RAST score.

A test for the detection of bacteria of the genuses Salmonella and Serratia and distinguishing them from the genuses Proteus and Providencia carried out in the presence of a diazonium salt and a synthetic enzymatic substrate in the form of an ester having an aliphatic chain of 7 to 10 carbon atoms. Two reactions may be effected in the same reactive medium. The test may be associated with other tests such as the .beta.-glucosidase, .beta.-galactosidase and .beta.-glucuronidase research tests maki...

Theophylline concentrations in body fluids can be determined by a color reaction. The theophylline is converted to theophyllidine by reaction with an alkali such as sodium or potassium hydroxide at an elevated temperature and, after neutralization of the alkali with an organic acid, the theophyllidine formed is coupled with a chromogen to yield a color whose depth is proportional to the theophylline concentration in the body fluid being tested. The improved procedure utilizes a solid alkali for ...
