Abstract
Provided is a test apparatus that tests a device under test that outputs a plurality of modulated signals modulated with carrier signals having frequencies identical to each other, including a synthesizing section that synthesizes the plurality of modulated signals to output a synthesized signal; an AD converting section that samples the synthesized signal to output a digital signal corresponding to the synthesized signal; and a judging section that judges acceptability of the plurality of modulated signals output by the device under test, based on the digital signal.
