Hello! The main factor that determines how fast you can acquire is the type of data acquisition board that you have. In the user=92s manual of your board, under the specifications section, the maximum sample rate is listed and you cannot go any faster than that.
Once you have written your data acquisition program, its size also determines how fast you can acquire, because time is needed for every function in your program to be executed. Keep in mind that this is system dependant (processor speed, memory, etc.). You can benchmark your program as Herbert suggested. I am including some links that can help you do this. <a href=3Dhttp://digital.ni.com/public.nsf/websearch/0E7EA68BFB2BCD37862562A80= 073708D?OpenDocument>How do you determine if you are acquiring data too fast or doing too much processing during a continuous data acquisition?</a><br> <a href=3Dhttp://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=3DC= EA0BF441BE67507E034080020E74861&p_node=3DDZ52303&p_source=3Dexternal>Benchm= arking Multiple E-Series or PCI S-Series Boards and Writing to Disk</a><br> Hope this helps!
