Rohde & Schwarz: Spectrum Analyzer Fundamentals - RF CafeAs wireless devices and systems spread across every industry, spectrum analyzers serve as an essential RF test tool for characterizing signals and making frequency measurements. 

Download Rohde & Schwarz's definitive guide to understanding the technology behind spectrum analyzer measurements.

In this primer you will learn about:

  • Basics of Spectrum Analysis
    • Time and Frequency Domains
    • FFT Analyzers
    • Analyzers using the Heterodyne Principle
    • Settings for Using a Spectrum Analyzer
  • Nonlinear Devices Under Test (DUTs)
  • Crest Factor and Complementary Cumulative Distribution Function (CCDF)
  • Phase Noise Measurements
  • Mixers and Mixer Measurements

Excerpt from Chapter 2, "Basics of Spectral Analysis":

R&S Chapter 2, "Basics of Spectral Analysis" - RF CafeFor the most part, the structure and content of this chapter have been taken from the book Fundamentals of Spectrum Analysis by Christoph Rauscher [1]. That work contains further references and links for a more in-depth look at this subject. 2.1

Correlation between the Time and Frequency Domains Electrical signals can be represented and observed in both the time domain and the frequency domain (see Fig. 1).

These two methods of representation are linked together via the Fourier transform, which means that a characteristic frequency spectrum for every signal can be represented in the time domain. ...

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
