I'm posting this for somebody without USENET access. Please reply to the address given in article below. ----------------------------------------------------------------------- Hello, PC world! A friend of mine (an electrochemist) is trying to find an inexpensive data acquisition system for an IBM PC compatible; they only have access to Taiwanese clones, so I expect an AT is tops. The system should permit one to gather about 100,000 data points, compute averages etc., store them and begin afresh. One "data point" means 3 values: variable potential within -3 -- +3 V with 1 mV accuracy, current within 10E-9 -- 10E-3 amp with accuracy 1E-9, and something called phase angle (I'm not sure I understand it correctly, so I won't try to describe it.) They have some quite able electronics technicians who should be able to take care of the A/D interface etc; the thing that's needed is software. It sounds like something simple. Has anyone heard of such a beast? Sources? I'll appreciate any/all information you can provide. Please reply to NBEHR @ ECNCDC.BITNET, if possible. Thanks -- Eric. ----------------------------------------------------------------------- | Marek Behr | mf12605@uc.msc.umn.edu (internet) | | University of Minnesota | AE01005@UMNACVX (BITNET) |

Your friend may wish to talk to National Instruments in Austin, TX. They have a package called LabWindows that may provide the hardware and software solution for your friend. They can be reached at 1-800-IEEE-488. Mark Miller Boeing Commercial Airplane Co. Seattle, WA /* My opinions are mine and mine alone. */
