My LabView program times out before HP35670A completes long sweep.  Is there a timeout in one of the the instrument driver VI's?

I want the program to wait for the 35670A to finish the sweep.

Usually, yes.

And which VI might that be?

Do you have Context Help turned on? You can simply browse through the fuctions to see which might have a timeout input. It took me only a short while to find 'Act Wait OPC'. You have not posted your code so I have no idea what functions you might be using.

Thanks for the help.  Changing Actn Wait OPC timeout doesn't resolve issue.  The standard vi's with the instrument driver don't seem to wait for the 35670A to finish a scan.  I want the program to poll 35670A status and when the scan is complete, transfer trace data.  My program sequence is Initialize, Actn Start Stop Cont then Data Coord Trans Data.  Other settings like channel configuration, instrument mode, etc are set manually.

Have you tried increasing the VISA timeout?
