Num of Thinning
Set how many data will be skipped before the next analysis data is adopted when the data to be analyzed is
generated from the measurement data. 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.
Any value between 0 and 31 can be set, but the number of measurement data cannot exceed the total
number of data to be analyzed that has been generated through thinning.
The following is the example of how data to be analyzed is generated when the number of thinning is set.
[Example] How data to be analyzed is generated when the number of thinning is set to “2”
• The number in each cell represents a measurement data number, where measurement data are
arranged in the order of 0, 1, 2, 3...
• Generation of data to be analyzed starts from measurement data 0.

Data to be analyzed
Fig. 13.17 Relationship of Measurement Data and Data to Be Analyzed
In the above example, the number of thinning is set to “2,” meaning that every third measurement data is
adopted for analysis.
(Note) Any change to the set number of thinning will be reflected only when FFT analysis is performed.
Unless FFT analysis performed, the change will not be reflected in the FFT analysis result.
(Note) 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.
(Note) The default value of 0 is set immediately after the PC software has been installed.
Hereafter data will be adopted
in the same manner until the
number of use data is reached.
