Re: Reccomended Computer Interface Systems

For dynamics experiments, collection rate is  ot an issue.  30 pts/sec for
a car rolling is plenty.  Using the ULI II, you can collect force-only
data at 11 kHz.  Again, what into labs do you do that you need a larget
collection rate?

I use Vernier hardware and am extremely happy with the tech support and
the hardware.  When I made my initial purchase 3 years ago, I evaluated
Vernier's MPLI and ULI, Pasco's Science Workshop, and Eched Robotech's
Handilog.  The handilog was by far the best and most useful package, but
$1,000 per set up was a tad too pricey.  Vernier, at the time, was the
most user friendly.  Vernier comes with adequate analysis options and the
hardware is first rate.  I assume that Pasco has made major improvements
to their program since I last saw it.
