formatting out put data

[Bale-suk]

I'm a beginner, I was trying to read data from two channels. I'm using "2 channel Oscilloscope.vi" (see attachment) that I found from vi examples. To read data from this vi I insert "Write LabView Measurement" vi and run the program.
Here comes the problem.
1. The data is bulky, how can i collect data in minute wise, not in second base, or how can I solve this problem.
2. After ever 499 data collection (it might be 499seconds), the title appears again and the numbering start from No. 1.
3. For every data i found from the two channel, it gives two columns of time data, that i don't need.

Generally I want to have my data from the two channel in a time (minute) basis, and save it to one file.

P.S. I'm using traditional DAQ with DAQCa
rd-AI-16XE-50.

Most of your problems can be solved by configuring the Write LabVIEW Measurement File VI differently.

1. Set the X Value Columns to Empty Time Column to get rid of the extra time data from you file.


2. If you want to continue saving to multiple files, click on the Settings... button and change the Width from 3 to 4. This will give you a lot more potential files.


3. If you want everything in one file, click Save to one file in the main dialog. Given the amount of data you are saving, this might not be a good idea.

Unless you really want to use text based files, given the amount of data you are generating, you may want to consider using either NI-HWS (available on the driver CD) or the new Storage VIs intr
oduced in LV 7.1.

NOTE: LabVIEW is a very feature rich language. A few minutes of searching around will generally get you the capability you want. If it doesn't, you can always roll your own. LabVIEW is a fairly decent general purpose language (please share if you do, that's what this forum is all about).
