Forget labview also. We don't use it. We do however use the base drives
that come with the gpib cards, they usually have pascal, C, Qbasic and a
few other versions in the set. They only get you on to and off of the bus
and what you say to the address instrument and it's replies have to be
known and part of the higher level code. It's pretty trivial but does
require knowing the controlled instrument "language".

NEC 7210 is a good part if you can find them.

Several, not much differene in them. Not cheap either!

You need a gpib driver (like driving a NIC) and then a high level driver
that will be instrument specific. We have about different ones to
accomodate each one of the different DMMs we use! For example the
Keithley 199 uses one format, k2000 a different one and the 2001 either!
then the new HP we got is of course different... grrr!
