Tip: 

Alternatively to steps 5 to 8, you can double-tap the measurement results, and

select the appropriate measurement group and the measurements in the sidebar.

9. To remove the histogram, tap the "Delete" icon on the toolbar, and then tap the his-

togram.

The histogram and any measurements based on that histogram are deactivated.

Performing a Basic FFT Analysis

During FFT analysis, a signal in the time domain is converted to a spectrum of frequen-
cies. A basic spectrum waveform can be displayed quickly.

The usage of FFT is also shown in a short video that is available on the instrument:
"File" menu > "Tutorials" > "FFT".

1. Restore the default signal channel settings by pressing the [Autoset] key.

2. Tap the "FFT" icon on the toolbar. Then tap the diagram.
