4.3.1.1
“Processing Parameter” in “Option” Button
The “Processing Parameter” menu (See Figure 4.21b) allows the user to select/set the
following parameters:
Parameter Name
Parameter Function
FFT/Data Block Size
FFT/Data Block size for processing
Play Execution
Delay
This sets time delay between each block calculation, in msec, minimum is
1 and maximum is 32768.
Block Overlap(%)
This sets the percentage of overlap from one processing block to the next.
Analysis Window
Overlap
This sets the percentage of overlap from one analysis window to the next.
If analysis window is (0-5) sec and overlap is 50%, then next analysis
window is (2.5-5) sec.
Fixed Sliding
Window/Fixed Total
Reduction
This option applies to the “Time Domain Waveform Reduction”
processing only. “Fixed Sliding Window” reduces the time data into 1
point for the reduction set. “Fixed Total Reduction” reduces the time data
to the fixed total number of points regardless of the size of input.
Window Type
Type of window: None, Flat Top, Hamming, Hanning, Kaiser Bessel, and
Rectangular. – Applied to all spectral analysis
No of Application
For Multiple window application. – Applied to all spectral analysis
Peak Frequency
Locking Mouse
Marker Window
The range where the highest peak is to be searched from current mouse
position. This is only used in finding peak. – Applied to frequency
domain function display.
Spectral Type
This option sets the spectral types as “Power Spectrum Density,” “Power
Auto Spectrum,” and “Auto Spectrum.”
Row/Col
Arrangement
This option applies to setting plots using “Quick” menu only. This option
sets the row/column major plot channel assignment.
Histogram Plot Para.
This option is for use in “Statistics” display.

“Sound” Option in “Option” Button
The user can enable this option, Spectrogram Waterfall Topo, and listen to the sound of
raw data being processed. It can be selected in the Right Mouse Button option. When
that option is switched on, figure 4.25, a sound menu appears. Once this menu is set, the
user can listen to sound of data as the file is being processed. Parameters and their
explanations for this menu are listed in the following table. When using the sound option
in the “Function Window,” turn the sound option on. When clicking on the sub-plot
whose signal to be played, the menu symbol “M” of that sub-plot will turn into “S” to
indicate the sound channel selection. To switch the sound to other channel, simply click
on the next desired sub-plot.
