Labview is not able to pull data from a HP4194A and gives me the error code 1073807202.

[Motint]

I am trying to get a graph of the impedance of a capacitor from the HP4194A to my laptop and am using a ni GPIB-USB-HS connection. I have downloaded the newest drivers and am using LabView 8.2. I initialy thought that it was a connection problem because the Measurement and Automation application could find the HP4194A but it did not respond to the *IDN? query. However, the HP4194A did respond to the query ID? which I found while looking through the users manual. What else should I try to get the data I need?

Thanks

Have you verified the GPIB address is set correctly?

Yes it is set to 10 on both the HP4914A and in LabView.

The HP4194A is an old instrument, and as such it's not unusual for old instruments to not implement the standard SCPI commands. Hence, it having "ID?" instead of "*IDN?". That said, which driver are you using? Is it this? When you say you're not able to pull data, please be more descriptive. Are you getting an error? If so, what is it? Which VIs are you using? Are you using an example VI? If so, which one? We are not mind readers, remember.

The error code of -1073807202 indicates that you did not install NI-VISA. This is required for the LabVIEW driver and if you had done a search for that error code, you would have found numerous posts and the solution.

Hah. Completely missed the error code in the title of the post.

Thanks. I did find that link to the NI-VISA earlyer but I missed the Learn how to install link. So I'm trying that now to see if that fixes the problem.

Thanks again.
