Mixed Analog-Digital Instrumentation for Software-Defined-Radio Characterization
Catherine A. Remley, Nuno Carvalho, Pedro Cruz, Kevin Gard
This paper presents a new type of analog-digital mixed-domain instrument that is specially tailored for software defined radio characterization. The instrument allows the utilization of analog instruments such as vector signal analyzers and network analyzers to characterize components based in the digital domain, such as analog-to-digital converters or field-programmable gate arrays. In this paper a study of the implementation of the mixed-domain instrument is also given.
