FFT Measurement Hints

The number of points acquired for the FFT record can be up to 65,536, and when 

frequency span is at maximum, all points are displayed. Once the FFT spectrum is 

displayed, the frequency span and center frequency controls are used much like 

the controls of a spectrum analyzer to examine the frequency of interest in greater 

detail. Place the desired part of the waveform at the center of the screen and 

decrease frequency span to increase the display resolution. As frequency span is 

decreased, the number of points shown is reduced, and the display is magnified.

While the FFT spectrum is displayed, use the 

[Math]

 and 

[Cursors]

 keys to switch 

between measurement functions and frequency domain controls in FFT Menu.
