Alright I seem to be able to get data from the scope but I get a "Drawing Failed" error when I try to open the created file to view it.  I am writing the data to the GPIB port instead of a file. Any ideas what could be wrong. Again i am using the 3034B scope

Hello,

  The saga continues....I am having less random erros , but they are still there. try putting a short delay between a VISA write and a VISA read in the vi's that communicate with the scope might do it. . In a short terminal emulator vi this worked for me with my scope.

Hello,

   I have tweaked the screen capture code some more and I have been able to succesfully over 50 consecutive scope images without an error. The code is presently kludgy, but it works. I will clean it up and will post it on this forum. I am going on vacation tommorrow and will be gone for a 10 day vacation in Cape Cod to catch the rays, walk along the beach with my family, fly kites, and eat some fresh seafood. So I want to get this code in the forum so that hopefully the "fabb user" could try the code and let me know how it works for them.  I will be here the rest of today, so the sooner you grab the code and try it out you might be able to catch me before I leave on vacation. Please be aware that when I do get back, I will have to play catchup for a while before I can revisit the code.

Here is the code, saved as a Labview 8.0

Hello,

    I have been doing some testing with some updated code and things are working better, meaning that I am not getting the random com errors and things are working faster and also working correctly. The biggest thing I have changed is to increased the VISA timeout to 20000.  When I have done some more testing and I have cleaned up the code I will post it on this forum

Hello,

  Attached to this E-mail is a updated version of the TDS5034B screen capture. I have added the ability to select how the screen shot comes out of the scope, GPIB or Ethernet. I will be updating this again with a option to select the image format.

Hello,

I have a TDS3054B scope and cannot get the code to work properly. I am constantly getting the error code: -1073807339

I have tried to change the wait times, command calls, but no luck. Has anyone else been able to get this to work with the TDS3054B? Thanks

Hi ONMaverick,

Please look at this knowledgebase article for more information in your error. This is a timeout error and can generally be fixedby setting a fixed timeout value. Hope this helps.

My mistake--I did not link the article in the last post. Here it is.

I hate to disagree but I believe that the majority of times a timeout occurs during a VISA Read and the cause is usually a failure to send the correct command to the instrument, a mismatch in the com settings, or using the incorrect type of serial cable.
