Signal Analysis Measurement Fundamentals

For an RF engineer, a spectrum analyzer or signal analyzer is an essential and fundamental measurement tool, used in all phases of the product life cycle. Key characteristics such as performance, accuracy and speed help R&D engineers enhance their designs and help manufacturing engineers improve test efficiency and product quality. This note offers a variety of techniques that will help you master signal analysis in your application. Our focus is on helping you optimize attributes such as measurement noise floor, resolution bandwidth, dynamic range, sensitivity, and more, while maintaining speed and productivity.

We generally use the term “signal analyzer” to indicate an instrument that has a spectrum analyzer architecture and an all-digital intermediate frequency (IF) section that processes signals as complex vector quantities, enabling multi-domain operations such as digital modulation analysis and time capture.
