Hi Gen,
I looked around for LV drivers for the 2440. The "oldest" I could find is LV6.
You may have to write some of the drivers using instument commands. A bit tedious, but it can get you there.
Did you try contacting Tektronix and find out if they do have LV5 drivers or DLL's that you could use. Yes, I know that it is discontinued and no longer supported... Try anyway...
-nothing ventured, nothing gained-- It doesn;t hurt to try.
