The invention discloses a circuit testing apparatus for testing a device under test. The circuit testing apparatus includes a filtering circuit, an amplifying circuit, a comparing module, and a result-examining module. The filtering circuit filters an analog output signal generated from the device under test to generate a filtered signal. The amplifying circuit amplifies the filtered signal to generate an amplified signal. The comparing module compares the amplified signal with at least one reference level to generate at least one result signal accordingly. The result-examining module examines the result signal to determine a test result for the device under test.

Circuit testing apparatus

A testing apparatus includes a public test board, a single DUT (device under test) test board and a holder. The public test board includes a plurality of public test channel sets each having a plurality of public signal terminals for receiving test signals. On the single DUT test board, a plurality first signal terminals are arranged according to the pin layout of a DUT, a plurality second signal terminals are arranged according to the terminal layout of a public channel set, and a plurality traces are arranged for electrically connecting corresponding first and second signal terminals. The holder can connect the pins of the DUT to corresponding first signal terminals.

Testing apparatus with high efficiency and high accuracy

The invention discloses a testing circuit board for placing a device under test and further testing the device under test according to a plurality of testing signals generated by a tester.
