Abstract
A test system may include a test device, a switching unit and/or a test board. The test device may be configured to generate a first test signal swinging between a first voltage level and a second voltage level, and the first voltage level may be lower than the second voltage level. The switching unit may be coupled to the test device, and configured to switch the first test signal to provide a second test signal swinging between a third voltage level and a fourth voltage level. The third voltage level may be lower than the fourth voltage level. A plurality of devices under test (DUTs) may be mounted on the test board. Each of the plurality of DUTs may be connected in parallel with respect to one another to the switching unit through a transmission line.
