I am trying to control the agilent E4980A LCR meter but I am having some trouble. I have downloaded the drivers and they seem to work OK. My problem arises when I try to run a sweep of say frequency. The labview program never seems to run the all the frequencies, just one. I am trying to dump everything into a text file with frequency, dc bias, dc source, primary parameter, and secondary parameter all stored in the file. Is there any guidance I could get? Thanks!

It's been a long time since I did anything with the meter and I don't have one anymore. Once the sweep points and list bands are loaded, can you perform the test manually. For that matter, if you do everything manually, does the test run like you expect?
Instrument specific questions might get an answer here from someone with current experience but you should also check with Agilent, especially if you can't do the test manually.

Yes I can do it manually. Once I set the list up with the program I can make it run through the list by doing it manually. However, I would like to do this via labview if possible. Thanks for you help.

One option is for you to look at the programming manual for the instrument and see what command or series of commands need to be sent to make the instrument go through the list. You can then compare those commands to what is being sent by the LabVIEW Instrument Driver. If they differ, you can create a VI that sends the correct commands and see if that takes care of the issue. If that does resolve the issue, you can explain your fix and then NI can update the released instrument driver.
