  • Description
  • A spectrum analyzer (also called Signal & Spectrum Analyzer, Frequency Analyzers or RF Spectrum Analzers) measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.
