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!) Or use the •
internal generator output.
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 channel and volts/div setting ( • 2 )
