Connecting an instrument using GPIB-USB connection.

Solved!
Go to solution

I am trying to use a GPIB-USB adapter to control a Source Measurement Unit from LabView. However, I am having trouble getting my instrument drivers to recognize the GPIB address that specified for the device. I've attached an image below of address specified by IO Keysight Connection Expert. I am currently trying to initialized the SMU with the GPIB driver I've attached below. Due to my limited knowledge on instrument control in LabView, how should I approach gathering the correct GPIB address and recognizing it within my VI?

Hello,

 

I would recommend using NI MAX to configure and find more information on your GPIB device. Information on this can be found in the link below.

Give the above a read, and see if that helps you find information on the device.

Shamik,

 

Thanks for the help. I was able to enable both Keysight Connection Expert and NI MAX and get my Keithley SMU recognized on NI MAX. However, now when I enter my GPIB Address ("24") into my Labview Keithley driver, which I attached above, I still cannot communicate with my SMU. How can I establish this connection from within LabView?

Hi wyattcurtis824,

 

Before we dig into the LabVIEW code, I would recommend opening a Test Panel in MAX and trying to communicate with. Are you able to send commands via Keysight Connection Expert or NI MAX and see valid data?

 

Also, when you run the driver vi in LabVIEW, does it return an error in the error out box? If so, what error is it?

 

This information shoule help us get to the root of the issue.

Thanks for the help!

 

I was able to get the SMU to communicate with LabView by testing a connection in MAX and finding the root error.
