IV curve for the Keithley 6430

I "finished" a simple IV curve application for the Keithley 6430 this morning. For those of you who are interested, you can pick up the VI here. You will need to use the included debugged Keithley library, kei6430.llb. I would put this in the C:/Program Files/National Instruments/LabVIEW 7.0/instr.lib directory. The main file, anu_02.vi, can be run from anywhere. The VI itself is quite simple, simply enter the start and stopping points and the number of points and it will do a linear sweep. Everything else is in AUTO mode.

I'm an outsider working on a similar project and am new to LabView. Would it be possible for you to email the files as an attachment, that would be of good help. I work at ORNL and am working on inchworms. Let me know.

I try to do the same thing as you done there (IV courve). Can you e-mail me the zip file? because i can download it from you website. What i trie to do? I wana use 6430 as a source (comand it from GPIB) amplified the signal on a amplifier (SR560) and acquire the signal on a DAQ board.

I'm using Keithley 220 as current source instead of Keithley 6430, and sending current across a resistor to measure voltage drop using HP multimeter, from GPIB. Final goal is to obtain I-V curves. How would it be very different from what you gave before? Would you have a zip file for it that I could download? Thanks.

Now I construct the program to control 6430. Thank you for your "I-V curve" program because I'm making my own program referring to yours.
Then I have a trouble. 1st time I ran my program and yours, there was no trouble. But 2nd time or later, an error has occured in "6430 initialize.vi". The error message told me that the trouble occured at "GPIB write". Now I have not found the cause of this error, so will you advise me?
I'll add the information of my testing condition. The OS in my PC is WindowsXP, and the way to communication between PC and 6430 is GPIB-PCMCIA card produced by National Instrument.
