Start Time [sec]
Specify the start position of the range of measurement data to be used for FFT analysis, in units of [sec].
Enter a value directly in the input field or click the buttons on the right side of the input field to change the
current setting, to set the analysis start time.
You can also set a desired analysis time by dragging the mouse while holding down the right button over
the measurement data graph to move the two red vertical lines displayed on the graph.
Note, however, that the end of the data to be analyzed cannot exceed the end of the measurement data.
Any change to the set analysis start time will not be reflected in the FFT analysis result unless FFT analysis
is performed again.
If the data has been read from an existing analytical data file (file extension: fmd), the new setting will be
saved when the file is saved.

Num of Use Data
Set the total number of data to be analyzed. Clicking the T button on the right displays a list, where you can
select a desired number. The following values can be set, but the set value cannot exceed the total number
of data to be analyzed:
• 128
• 256
• 512
• 1024
• 2048
• 4096
• 8192
• 16384
Any change to the set number of use data will not be reflected in the FFT analysis result unless FFT
analysis is performed again.
If the data has been read from an existing analytical data file (file extension: fmd/fsd), the new setting will be
saved when the file is saved.
The default value of 4096 is set immediately after the PC software has been installed.
