Note:
●
Signals with DC components or deviation would cause error or deviation of the FFT
waveform components. To reduce the DC components, set the Channel
Coupling
to
AC.
●
To reduce the random noise and aliasing frequency components of repetitive or
single pulse, set the
Acquisition
of the oscilloscope to
Average
.
10. Press the
Display
softkey to select
Split, Full Screen or Exclusive
display mode.
●
Split:
the source channel and the FFT operation results are displayed separately.
The time domain and frequency domain signals are displayed clearly.
●
Full Screen:
the source channel and the FFT operation results are displayed in
the same window to view the frequency spectrum more clearly and to perform
more precise measurements.
●
Exclusive:
the waveforms of channels are disabled, only the FFT operation
results are displayed in the window to view the frequency spectrum more clearly
and to perform more precise measurements.
