I am trying to recall state information to the HP8753ES by using LabVIEW. I have problems when I use HP8753 Save/Racall State.vi with the HP8753ES network analzer. The error comes when the vi sends the command INPULEAS (input learn string)to the analyzer following with the learn string that I saved. At the analyzer's display, it read "block input error". But I got no error when I save state information using that VI. Is there a way recall state properly?
