save a long experiment to many ASCII files

[Areli]

Hi I am using LabVIEW signal express ver. 2.5.1
I am doing an experiment that lasts more than an hour. My sample rate is 2.5 KHz and I am reading 1000 samples.
I do not want all data to be saved in an only ASCII (or .txt) file
because it愀 too much information to be opened  in an Excel sheet.

I would like to save only some adquired data in an ASCII file and then
save next adquired data in another ASCII file, and so on, in order to
have less information in an only file.
I do not know how to do this without stopping my experiment each time I want to save.

Any help will be appreciated, I am new to this software.

Thanks,

Areli

A lot's of way could be use for doing that.
You can split you data in a new files after a specific time or sample number.
The best way that you should do it, is by compressing data. Example using a filter that will not save the data if there is no diference between the new value and the old value. By doing this, you will be able to see all data in a single Excel Sheet. You can implement a bether solution by verifying if the new data is out of a +- specified error.
Try this and reply if it's working.
