How can I read this xls file to vibration measurement blocks??

[mujo]

Hi,

I want to use vibration toolkit to read and analyse

 measurements given in this file. First column is time data and second is measurement value in mV.

Hai,

File I/O palette has a vi named "Read from spread sheet file.vi" that will read the file in specified path and gives the content of the file as
2-D array.
Read the measurement file with this vi and carry out the analysis.

With regards,
JK

Hi,

I know for that block but as input to blocks that I want to use I need a signal as waveform . I use Labview 8.2. Is there any example for labview 8,2 about that I need.

Thanks

Emir

Hi Emir,

From your data it looks like you can read the file using the vi mentioned above into a 2D array.  Then use the Build Waveform vi under the waveform pallette.  dt is your sampling rate, which from your file you get by subracting one element from its predecessor in the time column.  Then wire the Y value to your mV column.  This will convert your data to a waveform.
