7.4. FFT Analysis
Data recorded with the following conditions can be used to perform FFT analysis if FFT is selected
as the waveform format in the control bar. Two types of FFT analysis can be performed at the same
time: Analysis1 and Analysis2. Refer to the "
10.4. FFT Analysis " for FFT analysis technology.
FFT Analysis
Recording device: SSD FFT analysis result
Sampling speed: 1 MS/s or lower (1) Analysis switch
Data format: NORMAL FFT waveform
Analog input amp: 1 channel or 2 channel
(1) Analysis switch
Switches the analysis results display between Analysis1
and Analysis2.
Switch the display by tapping the [<] and [>] key on the
left or right of the analysis or swiping the analysis
results area to the left or right.
(2) Meas. ON/OFF
Enables/disables the execution of FFT analysis.
(3) FFT settings
Tap this key to switch to the FFT settings screen to (2) Meas. ON/OFF
configure the FFT analysis conditions.
(3) FFT settings
FFT setup
When the settings are
complete, tap [←] or [x] on the
top title bar to return to the
original FFT analysis display.

Analysis settings
Common settings
Graph display: Select to overlay the analysis waveforms
over one screen Single or display them
separately on two screens Dual .
Sampling points: Select the sampling points for analysis. More sampling points means higher resolution for
the analysis frequency.
Window function: Select the window function for analysis. Change the setting according to the state of the
input signal.
AVG process: Specify the type of averaging for the analysis results and the number of additions for the
averaging.
