FFT Measurement

FFT is used to compute the fast Fourier transform using analog input channels or

an arithmetic operation g(t). FFT takes the digitized time record of the specified

source and transforms it to the frequency domain. When the FFT function is

selected, the FFT spectrum is plotted on the oscilloscope display as magnitude in

dBV versus frequency. The readout for the horizontal axis changes from time to

frequency (Hertz) and the vertical readout changes from volts to dB.

Use the FFT function to find crosstalk problems, to find distortion problems in

analog waveforms caused by amplifier non-linearity, or for adjusting analog filters.

To display a FFT waveform:

Press the

[Math]

key, press the

Function

softkey and select

f(t)

, press the

Operator

softkey and select

FFT

•

Source 1

— selects the source for the FFT. (See

"To perform transforms or

filters on an arithmetic operation"

on page 75 for information about using

g(t)

as the source.)

•

Span

— sets the overall width of the FFT spectrum that you see on the

display (left to right). Divide span by 10 to calculate the number of Hertz per

division. It is possible to set Span above the maximum available frequency, in

which case the displayed spectrum will not take up the whole screen. Press

the

Span

softkey, then turn the Entry knob to set the desired frequency span

of the display.

•

Center

— sets the FFT spectrum frequency represented at the center vertical

grid line of the display. It is possible to set the Center to values below half

the span or above the maximum available frequency, in which case the

displayed spectrum will not take up the whole screen. Press the

Center

softkey, then turn the Entry knob to set the desired center frequency of the

display.

•

Scale

— lets you set your own vertical scale factors for FFT expressed in

dB/div (decibels/division). See

"To adjust the math waveform scale and

offset"

on page 75.
