I use Labview or HP Vee to control instruments and collect data and use Mathematica to analyze the data collected. But I don't use Mathematica to *collect* data.

Basically, I have a custom program written in either Labview or Vee to control the instruments and collect data. This program saves the data in an ASCII file which typically has a reading per instrument per line. I use a combination of Mathematica and a text editor to reformat the file in a bit more convienent form. Finally, I use Mathematica to plot and otherwise analyze the data.

Since I am not doing an analysis in real time, there is no issue with separating the data collection (Labview, Vee) from the data processing/analysis (Mathematica). For real time monitoring of the data as it is being collected, I use the plot routines avaliable in Labview or Vee.
