The Spectrum Analyzer Module
What?: Powerful feature which allows visualization of the frequency spectrum of a signal, using FFT
(Fast Fourier Transform) analysis.
How?:
• Connect the scope input to the circuit under test. (observe the max. input rating of the scope!).
• First observe the signal on the scope screen (see previous page).
• Check that the signal is not over the maximum of the screen.
• Start the spectrum analyzer.
• Press „RUN‟ (1).
• Select the appropriate frequency range. Make sure your setting will capture any signal change of
interest (3).
• If wanted, set the appropriate volts/div setting (2).
