which instrument driver should I use?

Hello, I am trying to collect data from Keithley 2400 and plot voltage-current graph in labview. I noticed NI has a driver for this instrument and Keithley also privides one. So which one should I use? Do they make any difference? Thanks!

Keithely actually has a couple available. One is old (LV 5.1) and does not use VISA. The other is an IVI driver. The one from NI is only for LabVIEW 8.x, is fairly new, and is written entirely in LabVIEW. Unless you really have a need to use IVI, I would recomend the one from NI.
