This paper presents a simple test-bench providing RF vector measurements of typical wireless communication system building blocks under realistic signal conditions. The instruments are synchronized using an experimental method based on the signal path's time delay estimation. As an example a 2.45 GHz CDMA-QPSK complex digitally modulated signal was used. The ultimate goal of this test-bench is to deliver accurate measurements leading to evaluation of the quality of large-signal behavioral models of the measured RF blocks.
