Abstract:
1. A test system comprising: a test device configured to generate a first test signal swinging between a first voltage level and a second voltage level, the first voltage level being lower than the second voltage level; a switching unit, coupled to the test device, 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 being lower than the fourth voltage level; and a test board including a plurality of devices under test (DUTs) mounted thereon, each of the plurality of DUTs being connected in parallel with respect to one another to the switching unit through a transmission line, wherein the switching unit corresponds to a transistor including a control electrode configured to receive the first test signal, a first terminal coupled to a first power supply voltage and a second terminal coupled to a second power supply voltage, the second test signal being provided at the first terminal.
