I am looking to control the power supply and perform real time measurements with a Keithley 35617EBS electrometer. The Keithley will control the biasing on and collect a integrated charge (in nanocoulombs) from a parallel plate ionization chamber. I am using a NI GPIBUSB-HS as an interface.
Is there example that I can expand on?
You can use NI-VISA commands to try and communicate with this device. I wasn't able to find the user's manual for the Keithley instrument, but there should be a listing of the commands you can send to your instrument in that manual. A good example to look at and build on is GPIB-VISA.vi in the LabVIEW Example Finder. You will need the NI-488.2 and NI-VISA drivers to run this example, and to communicate with your instrument. These drivers can be found here : (NI-488.2) http://joule.ni.com/nidu/cds/fn/p/sn/n23:5340/lang/en and here : (NI-VISA) http://joule.ni.com/nidu/cds/fn/p/sn/n23:1640/lang/en . The latest versions of these drivers are NI-488.2 version 2.5, and NI-VISA version 4.4.1.
You can find the GPIB-VISA.vi example by opening the LabVIEW Example Finder from Help->Find Examples... in LabVIEW. In the Example Finder, verify that you have the Browse tab selected, and navigate to Hardware Input and Output -> GPIB -> GPIB-VISA.vi
