About VSA Concepts

The VSA (vector signal analyzer) concepts section includes information you may need when making measurements with Keysight 89600 Vector Signal Analysis software. This includes information such as:

• Analyzer Basics—the different types of analyzers and how the 89600 VSA software differs from conventional analyzers.

• FFT Basics—a thorough discussion of the terminology and methods used in analyzers including the 89600 VSA software to derive frequency (spectral) data from time records.

• Windowing and the FFT—how to correctly apply windows (such as a Hanning or Uniform window) when converting signals from the time domain into the frequency domain.
