    1. If you are using Windaq acquisition software, you can start it from its add-on sub menu
    2. Or, you can run the shortcut WWB FFT Viewer under Windows->Start->Windaq group
  • Due to the exclusive nature of the WWB link engine, only one copy of WWB FFT Viewr or WWB Advanced Event Navigator can be opened at any time
  • If a Wdq file is being acquired to by Windaq Acquisition software, it should be closed first before it can be opened by WWB FFT Viewer
  • The WinDaq Waveform Browser used by FFT Viewer is c:\dataq\windaq32.exe by default.  If you wish to use another copy of WWB installed in a different directory, please edit WWBFFT.INI under Windows directory and change the key WWBPath. For example, if your preferred WWB is F:\Windaq\Windaq32.exe, you should change the key from WWBPath=c:\dataq\WINDAQ32.EXE to WWBPath=F:\Windaq\WINDAQ32.EXE
