Spectrum Analyzer Overview
The Spectrum Analyzer II software simplifies the debugging of frequency-related effects,
presenting a tool kit that mimics the interface of a traditional RF spectrum analyzer. You can
start using the Fast Fourier Transform (FFT) with little or no concern about setting up an FFT.
Key Features
Easy FFT Setup – automatically applies the FFT to your inputs and translates scope sample rate,
memory, and acquisition length settings into frequency domain relevant units. Just choose a
center frequency and span or a start and stop frequency. The resolution bandwidth is
automatically set to optimum resolution (or can be manually controlled).
Peaks/Markers – automatically and continually marks amplitude peaks on the spectrum trace
and displays their values in an on-screen table. Or, you apply moveable markers to the trace,
and the software automatically calculates relative and absolute frequencies and levels.
Spectrogram – displays a 2D or 3D rendering of spectra history.
Method of Operation
Spectrum Analyzer adds two dialogs for frequency analysis to your oscilloscope Analysis
menu options:
Spectrum Analyzer – the principal setup dialog, with controls similar to a traditional RF
spectrum analyzer. This is also where you control the spectrogram.
Peaks/Markers – where you control the Peaks and Markers features.
Set up your spectrum trace on the Spectrum Analyzer dialog by choosing your inputs (one or
more channel, zoom, math, or memory traces) and the frequency range of interest, just as with
an RF analyzer. Then, choose various analysis features, such as Show Peaks or Spectrogram, to
optimize your display.
