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.
