How modern spectrum analyzers are designed and
how they work
 As 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":
 For 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. ...
