For the capable RF engineer, continuous-wave (CW) and predictably-repeating signals are no great challenge—but today’s complex and agile signals and multi-signal environments are proving to be another matter. To keep up with evolving analysis needs, new types of signal analyzers and application software have emerged in recent years. Unfortunately, though, the relative benefits of these approaches are not yet widely understood.
This application note will discuss and compare the available tools and techniques for not only discovering elusive signals but taking the vital next steps in RF engineering to complete the solution. The material presented here will discuss approaches optimized for making precise and selective measurements of complex and demanding signals. This note also describes how to go beyond measurement to post-processing analysis, signal replay, and the transfer of captured signals to other analysis and simulation tools.
