Visa resource not found

[calvinkuek]

"Visa resource not found, please check your hp-ib bus address". This is the message from the error message.vi. This is the sub-vi that supply by Agilent . The driver is hp816x for the instrument Agilent 8163A. Can anyone please help me solve this problem.

I'm assuming that you have a VISA Resource Name control on your front Panel? If you click the little down arrow on the right does your instrument appear in the list? If it's not there, did you did a scan for instruments in MAX and did it appear there?

yupe.got gpib0::20: present.However, i have manage to solve that problem. Thanks for your answer.Anyway, now i found an error message when i connect the error message.vi to the prepare lambda scan.vi status- "NO appropriate Tunable Laser Source found". How to solve this problem? I connect Initialize->prepare lambda scan->Execute lambda scan->Get lambda scan result->close funtion together. I m using hp 8163A lightwave multimeter right now. I download driver from Agilent website-hp816X.
