Automate measurement for Keithley 2520

[nickwg]

Hello,

I am new to LabView for instrument automation. I am trying to write a LabView program that will measure the L-I-V characteristics of a laser diode from the Keithley model 2520. There are no instrument drivers for this tool, so I turned to Keithley and found the attached example program. It does not work when I attempt to make measurements. Will I have to write a program from scratch, or am I likely using the example program incorrectly?

Thanks,

Nick

What do you mean "does not work"? Do you get errors, wrong data, fried laser diodes, what?

What exactly doesn't work? What error code/message do you get?

When I set my desired parameters, I hit the "sweep" button, which then pauses and prompts me to save a file, presumably the collected data. The file is empty and nothing is displayed on the graphs in the VI.
