RF vector measurement test-bench for evaluation of behavioral model accuracy under realistic excitation

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 by use of an experimental method based on an estimate of the signal path's time delay. As an example, a complex digitally modulated signal with a carrier frequency of 2.45 GHz was used. The ultimate goal of this test-bench is to deliver accurate measurement data enabling evaluation of the quality of large-signal behavioral models of the measured RF blocks.
