Hi Im writing a program for measring a signal from Tektronix TDS3054B oscilloscope but during the running of the program it got an I/O error at the GPIB-read component. do you have any good suggestion for this problem. the picture of the secound sequence is athached

If you are asking for help, I suggest the following:

    1. The error you are getting

    2. Version of Labview and OS

    3. GPIB card if NI or not

    4. Condition when the error occurred

    5. The VI itself instead of the picture.

I would recommend you use the driver instead of your code. Definitely dump the sequence structure and use VISA functions instead of the low level GPIB.

this is just a little part of the program Im trying to write. but the error is occurring here.

Im using Labview 2010 and windows vista enterprise.

the error is  :   Error 6 occurred at GPIB Read in test1.vi

You are aborting the 'AUTOS EXEC' it seems. Like I said, use the driver instead of trying to reinvent the wheel.

sorry Im new in Labview . what do you meen with driver?

[Dennis_Knutson · Accepted solution]

The Instrument Driver Network has links that explain what a LabVIEW driver is and how to use one. Then go to the earlier link I gave you and download the appropriate driver. I would recomend the project-style driver.

Hi again

I have tried the VISA functions but I steal have the same problem. I can communicate with the Oscillator and send commands but not reading from it. I attach my new program.

the error is as following: Error -1073807339 occurred at VISA Read in test2.vi
