摘要: This paper presents a design methodology of multisine signals, so that they can be used as phase references or standards convenient for modulated measurements. To achieve an extendable measurement bandwidth, the spectrum of each multisine is designed with three successive segments, where the left (lower-frequency) and right (higher-frequency) ending ones have the same phase spectra. In this way several multisines, one by one overlapped at the ending segments, can jointly serve as an integrated phase reference/standard signal, which, in theory, has an arbitrarily extendable bandwidth. By the example of Schroeder phase relationship, the proposed method is experimentally verified for wideband-modulated measurements, where the designed multisines are used as the phase references and standards, respectively, of a Nonlinear Vector Network Analyzer test bed. In this work, a phase measurement error less than 1 degrees is experimentally confirmed for 1,601t measurements with 160MHz modulation bandwidth around 2GHz.
