Data Acquisition

[CHarris1918]

I am using the trial version of LabVIEW Signal Express for data acquisition. I started a test about a week ago to take a measurement on 8 parts using 16 channels inside the Switchblock. I have set it up to take a measurement every 180 seconds but when I exported the data to Excel I only see so many readings. For example I have measurement data in cells A8 to A519 which will yield 511 measurements at 180s. If the test was started on Tuesday of last week the information should show roughly 5000 measurements in the data. Does this version of LabVIEW overwrite the data after a certain period of time and is this data actually lost?

Sounds like you're experiencing something similar to this user.

How are you "Exporting" the data to Excel? You should have a Save to ASCII step in there which will log the data to a txt file in real time.
