LeCroy 9300C Series User Manual

10–23
FFT Setup
This example, illustrated below, shows how the oscilloscope
maintains the display factor. A sampling rate of 25 MS/s would
result in a full scale range of 12.5 MHz or 1.25 MHz/Div. To
maintain a display scale factor of 1,2, or 5 it decimates the
acquired waveform by 25 000:1 and calculates the FFT using a
2000-point transform. This results in a scale factor of 2 MHz/Div.
The display is truncated at 6.25 divisions to retain the original
12.5 MHz span.
