White Paper: Configuring Phase Coherent RF Measurement Systems: From MIMO To Beamforming

Source: National Instruments Corporation

Ever since the first radio waves were transmitted, engineers have continually sought new ways to utilized electromagnetic microwave signals. While RF signals have since been used for a wide variety of applications, two specific applications that utilize one common technology are wireless communications and radar. This article explains the technical requirements to configure a phase coherent RF generation or acquisition system. In addition, a step-by-step process to calibrate the phase delay between multiple RF analyzers to achieve the best possible performance is presented.
