I don't think you'll find any examples that suit, but that's life. It's rare
to find someone doing the same work with the same kit when more than one
instrument is involved.
Keithley should have examples for the electrometer that show you how to set
it up and take readings via the GPIB- that's the harder of the two
instruments because it does more. If they're not shipped, look on
www.keithley.com, since they have a large selection of example Labview
programs for their hardware- though I know nothing about that particular
instrument.
The power supply should be trivial; it should just have commands to set the
voltage (and current limit perhaps) and switch the output on and off. This
may be a good thing to learn to do GPIB programming on since there's
very
little involved. Check out the example
examples\Instr\smplgpib.llb\LabVIEW<->GPIB.vi to see how to send commands
and receive responses. Once you have a program that provides a sequence of
power supply voltages to your device, then start playing with the
electrometer examples and making something to read the current. Then put
them together and write a top level that builds a current/voltage plot for
the device.
I assume there's no problem with the physical connections and how to wire
the test device up to the instruments? That's out of the scope of this group
in any case.
