Hi,
Can you also perform the test manually like Dennis suggested? Have you looked at the manual to see if the commands necessary are there?

Hi,
I don't believe the necessary commands are available. What I ended up doing was making my own "sweeps" by looping any frequencies and voltages myself.

Thanks guys, I actually was able to find get the A4980 to perform the sweep via Labview but also discovered the list sweep is limited to 201 points. For my application I needed a higher resolution, so i also ended up using a loop and the read function to perform my measurements.
Thanks again

Hi Plexonite!, can you explain me how you plug the e4980 to your pc and make it all work? Im having troubles and your experience would be of great help! Thanks!

Com1 is the serial port and lpt1 is the printer port. Those are the only available VISA resources on your computer, Unless you were to add a GPIB interface, the list will always stay the same, no matter what instrument. Simple as that.
As I said, you have to modify the E4980 driver before it will work with RS-232. The 34401 driver, which you did not have to download, has all of the code for serial support in the initialize function.
I also mentioned that you should use a program such as Hyperterminal to test the connection. You need to verfy the com port settings and you need to verify that you are using the correct type of cable.
Since the instrument driver supports USB/Ethernet/LXI communication, if the instrument has these connections, you should try those.
