A local oscillator signal is output from a local oscillator using a reference signal produced by a reference signal generator. Similarly, a test intermediate frequency signal is output from a source oscillator using the reference signal. The test intermediate frequency signal is converted to a test radio frequency signal, with an up-converter using the local oscillator signal. The test radio frequency signal is supplied to a device under test, and an output radio frequency signal is received back from the device under test. The output radio frequency signal is converted to an output intermediate frequency signal, with a down-converter using the local oscillator signal. The output intermediate frequency signal is converted to a digital output signal, with a synchronized digitizer using the reference signal. Different phase signals of the output intermediate frequency signal are captured using the synchronized digitizer as the device under test is operated during a testing cycle.
