3 Signal excitation
This chapter is devoted to signal excitation for RF characterization. In that respect the main types of excitation used in the microwave field will be presented and their capabilities for wireless-system characterization, identification, and modeling will be explained. The main focus of this chapter is on the generation of special signal patterns and the explanation of the capabilities that those signals bring to the wireless metrology. This approach will complement previous chapters, by explaining how to generate and how to gather important information from specially designed signals. The chapter will start with the one-tone or single-sinusoid excitation.
