•
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.
•
Preset
— sets the frequency Span and Center to values
that will cause the entire available spectrum to be
displayed. The maximum available frequency is half the
effective FFT sample rate, which is a function of the
time per division setting. The current FFT sample rate
is displayed above the softkeys.

Press the More FFT softkey to display additional FFT
settings.
•
Window
— selects a window to apply to your FFT input
signal:
•
Hanning
— window for making accurate frequency
measurements or for resolving two frequencies that
are close together.
•
Flat Top
— window for making accurate amplitude
measurements of frequency peaks.
•
Rectangular
— good frequency resolution and
amplitude accuracy, but use only where there will be
no leakage effects. Use on self-windowing waveforms
such as pseudo-random noise, impulses, sine bursts,
and decaying sinusoids.
