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. Table 4.4 - Processing Parameters in “Option” Button 4.3.1.2 “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. 31
