Data Acquisition Cards



 Hello,
 I'm going to be getting a DAC card and some accompanying software for a
 PC in a couple weeks, and was wondering if anyone has any info they
 might think is helpful.  I'm not exactly sure what we will be doing with
 it.  However, this is what I know so far:  the card will be used to
 control a mass spec and sample the data.  Therefore we need input and
 output capabilities.  Most importantly i have no idea what sampling rate
 we need, nor the precision.
 General Info is what I'm looking for, tell me the name of a company that
 gave you real good service, or a good software package with lots of
 versatility...
