Post the Error message too which will help in guessing the problem.

This is the error message : "VISA Open in 8656b.vi"

Is the device being communicated with serial or any other protocol.  If it is serial see if the COM port that you are using is occupied or locked by some other devices configured in the system like modem.  Kindly post with more details or the VI you are using.

I am using GPIB interface. i've attached the code here.plz find it.

[JK1]

1. Use the GPIB Interactive control to query the device with standard commands and check the response. 

2. Is the GPIB address of the HP device set right and check if the same address is set in the VI.

2. See if the HP device needs some settings (manually) like changing between talke/listener mode, GPIB remote mode, address etc.,

In case anyone wants to solve the error, just by right clicking on an error indicator with that error code in it, you get an explanation. The error ususually means that NI-VISA is not installed.

As pointed out by dennis a driver required for communicating with the device which is not installed in the system and that is the error explanation give for that error.
