Need a VI for 4-probe conductivity with HP4155B, help?!!

[two_photon]

I'm wondering if anyone out there can set me up with a source for the necessary LabView VI's/drivers for making 4-point probe conductivity measurements with a HP4155B semiconductor parameter analyzer?  My LabView programming experience is minimal at best!  Thanks!

Hello Kevin,
       I recommend that you first go to IDNet and learn about using instrument drivers.  After that, you ought to download the LabVIEW Plug and Play driver for your instrument.  After you have connected your instrument and communicated with it in Measurement and Automation Explorer, you should try running some of the examples that come with the driver.  You are welcome to look through the driver and see if it implements the functionality that you desire.  If not, the beauty of Plug and Play drivers is that all the source code is right in front of you and after learning a little bit more about the instrument, you can add the functionality to the driver.  Let us know how it goes.

Cheers,

NathanT

There is an entire section of the NI website devoted to instrument drivers.  Here is a link to the one you want.

You will also want to dig up a copy of the programming/communications manual for instrument in question.  In this case you need to remember that HP is now called Agilent Technologies.
