13. Re‐sampling frequency‐ There are 7 different settings for re‐sampling recorded data: 10KHz, 20KHz,

30KHz, 40KHz, 50KHz, 70KHz, and 100KHz. It is recommended to use the lowest available sampling rate
for longer duration of recordings to prevent system from running out of memory during processing.

Window‐ is the PSD window and Hanning window is the most commonly used to perform the PSD

calculations.

Units‐ there are 2 settings for this field. Most commonly used for PSD is EU^2/Hz.
14. Min. Frequency (Hz) – enables zooming PSD and FFT plots to start from frequency set in this field.
Max. Frequency (Hz)‐ enables zooming PSD and FFT plots to end at frequency set in this field.
Graph Type – exports FFT and PSD plots in either Linear or Logarithmic.
15. Save‐ After setting all the re‐sampling parameters, press the save button and software will export all

selected file formats to the same directory as the original recorded data file. A series of plots will pop up
and disappear displaying the JPG, PSD, and FFT plots as selected.

16. Exported Files Directory‐ All exported files will be saved to the directory listed in this field. This is the

directory for the original data file selected in #1.

Process Completed‐ this indicator will illuminate bright green once the saving process is complete. It will

reset to matte green when a new file is selected.

17. Exit‐ once export is completed in step 15, there are 2 ways to exit the program. Pressing the Exit button

or from the File menu Exit.

See Figure 24‐26 for controls and displays.

Note: both continue and save buttons will be disabled if no data file is selected.
