Explanation
The DL9000 searches waveforms depending on whether or not the FFT analysis results
(see section 10.7 for details) are within the range that you set.
Search Logic
• AND: Searches for history memory waveforms that meet all search conditions 1 to 4.
• OR: Searches for history memory waveforms that meet any of the search conditions
from 1 to 4.
Search Condition Number
You can choose to configure a search condition from 1 to 4.
Search Source Item and Calculation
• Source Window
You can set the search window to FFT1 (the FFT of Window1) or FFT2 (the FFT of
Window2).
• Analysis Item
Select an analysis items that you want to use in the search.
• Basic: Searches an FFT analysis result (Peak).
• Calc: Searches a value determined by a calculation set in section 10.7.
Upper and Lower Limits of the FFT Parameters to Search
Selectable range of upper and lower limits: –1.0E+31 to 1.0E+31
Search Criterion
• IN: Searches for history waveforms whose FFT parameters are within the upper and
lower limits.
• OUT: Searches for history waveforms whose FFT parameters are outside the upper
and lower limits.
• X: Not used for the search.
